Mattress Thickness: 8, 10, 12, 14, 16 Inch Memory Foam Differences

Mattress Thickness: 8, 10, 12, 14, 16 Inch Memory Foam Differences

Mattress thickness is an important consideration when selecting a memory foam mattress.

You may be wondering if there is much difference between an 8 and a 10 inch mattress, or some other pair of options. The answer is yes there is.

Let’s look at the factors that determine the difference between an 8 inch mattress and a 10 inch mattress, a 12 inch mattress, or 14 inch mattress, and how that affects you.

Dimensions vs Thickness

Let’s get one thing out the way quickly. There is often confusion between asking about the actual mattress thickness and the mattress dimensions or size. Sometimes for example people ask “How thick is a King size mattress?”

As far as the actual thickness of the mattress is concerned, whether it’s King, Queen, Twin, Full or any other size, the standard thicknesses vary according to the manufacturer. Most commonly they are between 8 and 16 inches. As a guide, the most popular depth people buy are 10 and 12 inch mattresses. This is covered in more detail the sections below. As for standard mattress dimensions or sizes around the length and width, they are as follows:

Mattress SizeDimensions
King76" x 80"
Cal King72" x 84"
Queen60" x 80"
Full XL53" x 80"
Full53" x 75"
Twin XL38" x 80"
Twin38" x 75"

How Thick Should A Mattress Be?

When it comes to memory foam mattress there is a minimum mattress thickness at which a mattress offers a good performance. Go too low and you risk getting a mattress that is anywhere from uncomfortable to having a very short lifespan before it collapses.

There are 8 inch and even 6 inch memory foam mattresses on sale. We recommend you avoid them. 8 inch memory foam mattresses and below tend to be too thin to provide an adequate level of comfort and support for the average person. And even if they could do that, they would likely not last long before breaking down. The structure of 8 inch mattresses or less simply isn’t good enough.

Mattresses are typically composed of a memory foam layer and one or two other foam layers. The right balance is best achieved with a mattress of 10 inches and above. You can regard the recommended standard mattress thickness for memory foam mattresses as 10 and 12 inch.

Memory Foam Mattress And Body Weight?

How much you weigh is an important factor in choosing a mattress. We have already discussed that an 8 inch memory foam mattress or less isn’t really adequate for the average body. Similarly on the opposite end, the more you weigh, the thicker you’ll want the mattress to be.

10 inches is adequate for most people up to 250lbs, but if you tend to be a bit on the heavier side or want the extra thickness then you may prefer a 12 inch. And if you are particularly large and heavy, a 14 inch would be better. However, do also consider that the thicker the mattress is, the higher it’ll be to climb into bed.

So let’s now answer the question, “What is the difference between an 8 inch, 10 inch, 12 inch, or 14 inch memory foam mattress?”

What are the differences in memory foam mattress thicknesses?

When it comes to considering the difference between an 8 inch, 10 inch, 12 inch, or 14 inch mattress, you will probably want to filter out anything less than 10 inches, and then base your decision on your personal desire for comfort and your weight.

8 Inch vs 10 Inch Memory Foam Mattress

Some manufacturers try to pull the wool over people’s eyes with the 8 inch memory foam mattress. It really is a bit below par for the average adult person. It might be adequate for a teenager, child or a very skinny and lightweight person, but it is less than adequate for supporting the weight of an average person.

A memory foam mattress incorporates at least 2 different foam layers. An 8 inch mattress does not allow for an ample amount of foam layer material to produce a mattress adequate for most people. We do not recommend that you go for anything less than a 10 inch mattress.

10 Inch vs 12 Inch Memory Foam Mattress

If you’re wondering what memory foam mattress thickness is best, 10 to 12 inch is the sweet spot. For the average person up to 250lbs in weight, a 10 inch mattress will suffice. If you or your partner are over 250lbs, or if you feel you would appreciate the extra thickness then go for a 12 inch.

A 10 inch memory foam mattress provides the necessary amount of memory foam required for a comfortable night’s sleep for most people. This is why it is the most popular size, alongside the 12 inch for those that prefer extra thickness.

Memory foam mattresses are made of typically 2 or 3 foam layers. One layer is the memory foam material itself. The other layer or layers are supporting foam.

The difference between a 10 and 12 inch mattress for most people will be about the feel of the level of thickness or firmness. A like for like 12 inch mattress is going to have more of a floating feeling than a 10 inch because of the extra foam. For someone over 250lbs in weight, they might prefer to go for a 12 inch mattress by default.

While mattresses typically jump up 2 inch steps, 13 inch mattresses can often be found too. We regard them the same as considering a 12 inch mattress rather than a 14 inch for comparative purposes, and for consideration against 10″ mattresses.

4 Top 10-12 Inch Mattress Options

If you were also looking for some quick recommendations, here are 4 excellent choices.

12 Inch vs 14 Inch Memory Foam Mattress

Going higher than 12 inch (or 13 inch) to 14 inch or 16 inch is mainly for heavier people. It is also for those that have a strong preference for really thick mattresses.

It might be slightly less comfortable than a 10 or 12 inch for everyone else. If you want to go for one of these be sure to account for both the height of the mattress and the height of the memory foam mattress foundation.

Combine the height of the foundation with the height of the mattress and visualize getting into the bed. This will help you anticipate whether you’ll have difficulty getting into a bed that’s high, thanks to having such a thick mattress on it.

Memory Foam Mattress Foam Layers

Of course there’s more to choosing a mattress than considering its thickness. The internal construction of the mattress is also something to consider. The construction of a memory foam mattress usually consists of having a series of 2 or 3 layers of different types of foam.

The density and thickness of each of these layers can also vary. So you can have two 10 inch mattresses, yet the experience laying on each will be completely different because of these variations.

However, speaking just in terms of mattress thickness, if all things are equal apart from the mattress thickness, then a 10 or 12 inch mattress is fine for most people. Heavy people may wish to go for a 14 – 16 inch mattress.

Not all foam and not all manufacturers are of the same quality and standards. But we’ve saved you the time of having to do intensive research, scroll up for some great 10-13 inch mattress options.

Mattress Memory Foam Density

You may be wondering what is memory foam mattress density. The density of the mattress is another thing to consider. Memory foam density is a loose informal measurement of the quality of the mattress.

You will need to look for a mattress that ideally has between four to six pounds density. This is recognized as the optimum density range. Densities below 4lbs may be too soft. Densities above 6lbs may be too firm.

Well Known Manufacturer And/Or Good Customer Reviews?

Something else to consider of course the manufacturer. It helps to provide reassurance if the manufacturer is well-known?

That said, manufacturer reputation does not necessarily carry the clout that it once did. New players have entered the mattress market and disrupted the big brands control of the market. They have achieved this by introducing quality mattresses at much more affordable prices.

Such upstarts include Tuft N Needle and Leesa.

Customer reviews more than speak for the quality and value of these mattresses.

Difficulty Climbing Into Bed?

A point worth mentioning with the higher thickness mattresses in particular is that you will want to consider the combined height of your mattress and mattress foundation / base, especially if you have difficulty getting into bed. Fortunately, there are low profile foundations available which are lower in height than standard foundations if bed height is an issue.


Mattress thickness is an important consideration. 8 inches or less is best avoided, as these do not tend to provide an adequate level of support and comfort.

A lot of the quality mattresses on the market from reputable manufacturers and quality upstarts will be 10-12 inches. And of course you do not want the mattress to quickly thin out. So it makes sense to avoid the thinnest mattress in the range. So for most people, a 10 inch mattress will be a good thickness size for them.

A 12 inch mattress will be for people that generally prefer a greater level of thickness and sturdiness in their mattress. It is also good for people that tend to weigh a little bit more than the average person. This is the obvious reason that a thicker mattress, can better support the additional weight.

And itself follows then that a 14 inch mattress will follow the same principle. That is people that prefer an extra thick mattress will want a 14 inch mattress. Or people that are very heavy will prefer to have a 14 inch mattress.

So the main issue to consider before you entertain looking at mattress thicknesses, is to first filter out the mattress brands that are unknown. Or those have no evidence of customer appreciation.

And then you should check that the density of the mattress falls between five and six pounds. This is to ensure that the mattress is both not too firm, yet not too weak either.

Now that you know the importance of mattress thickness and other things to consider, you are well informed to buy a great mattress. If you would like some recommendations to consider, check out these highly rated mattresses below.

Bigger is not always better, especially in memory foam mattresses. A memory foam mattress has multiple layers; when added together, each layer contributes to the overall mattress height. Avoid judging a memory foam mattress by its thickness; rather, look at its density and load-deflection properties, as these characteristics define the quality of the mattress and its performance.

Dense Is Best

Being dense is typically associated with a lack of smarts, but in memory foam mattresses, being dense is a good thing. Manufacturers measure density by pounds per cubic foot. The density of the mattress determines how well it supports the body, not its thickness. Do not choose a memory foam mattress with a density rating of below 3 pounds per cubic foot for the memory foam layer, as it does not provide the body support needed. Top-name brands have beds that range up to 8 pounds per cubic foot on the memory foam layer.

Firm It Is

The second component used to determine the quality of a memory foam mattress is how well the bed deflects indentations. Called indentation-load deflection, this factor determines the hardness or softness of the memory foam mattress. It applies to the weight of pressure measured in pounds that are necessary to indent 4 inches of mattress at least 25 percent over a 50-square-inch area. Look for a mattress that has an ILD of at least 10, up to 14. Most top-brand mattresses weigh in with an ILD measurement ranging from 12 to 14.

Multiple Layers

Memory foam mattresses do not consist entirely of memory foam. Each manufacturer constructs a memory foam mattresses with multiple layers. Depending on the brand selected, the different layers include memory foam, gel, latex foam layers, quilting and covers. The optimum choice for the thickness of the memory foam layer ranges from 4 to 5 inches thick with a density of at least 5 pounds per cubic foot. The denser and thicker the mattress, the higher the price goes.

Mattress Components

When you want to buy a memory foam mattress, opt for companies that substitute many of the petrochemicals used to make these mattresses with natural products such as soy, green tea, cotton, bamboo or wool for quilting or batting layers and natural latex for that layer. Ask pointed questions about the manufacturing process and the chemicals used to expand the foam. One company uses water instead of chemical solvents, which often leaves a lingering and toxic smell on the mattress.

How Thick Should a Mattress Topper Be?

A mattress topper should add to the overall softness, luxuriousness and support of your mattress. It can increase the thickness of your mattress and make it feel more comfortable and even and prolong its lifespan, etc.

Before we explain how to make your decision easier, we will tell you something more about what are mattress toppers and what they are used for.They can be used for various reasons and your mattress topper thickness will depend on why exactly you need it.

Reasons for Buying a Mattress Topper

Prolonging the Lifespan of Your Mattress

As they age, and the more they are used,mattressescan become saggy and develop lumps and depressions in the sleeping areas. To prevent this, or at least slow down the process, you canuse a mattress topper.

If you choose the right type and correct thickness, the topper will rejuvenate your sleeping surface and slow down the aging of the mattress and the process of sagging and developing lumps. Depending on the current condition of your mattress, you may need a 3 or 4-inch thick topper.

Changing the Level of Softness or Firmness of Your Mattress

Some people may find their mattress to be either too soft or too firm for them and this can be right after the purchase or due to the long use.

You could change your mattress, but if you are looking for a cheaper solution, then a mattress topper would be an ideal solution for you.A mattress topper is far more economical solution as it will change the feel of your bed without costing you too much.

In this case, a 2” topper may be sufficient, although a thicker topper will provide a more lasting change especially forheavier sleepers.

Changing the Nature of a Mattress

If you want to see how it feels like to sleep on amemory foam mattresswithout purchasing one, or you already have memory foam and you don’t like it and want to trylatexor wool, in each of these cases,you can change the nature of your mattress by using the right mattress topper.

You can use amemory foam topperto get that contouring and hugging feel, or you can use a latex topper if you want to try out something more buoyant and different from memory foam. In such cases you can use a minimum 3” thick topper.

Increasing the Thickness of a Mattress

Some people may find that their bed is too low for them or that it is too thin and compresses pretty quickly under their weight. An extra 2 or 3 inches of a mattress topper could make some difference here, and it is less expensive than purchasinga new mattress.

Medical Reasons

If you have developed a condition that requires a good orthopedic support, then a viscoelastic material on the top of your mattress may be most suitable for you.

If your mattress is made entirely of latex or it is an innerspring and foam hybrid, then a viscoelastic ormemory foam mattress toppermay be the best solution for you.

A 3 or 4-inch memory foam topper might be enough and it will cradle your body, relieve pressure points and provide the right amount of support to those areas where it is needed most.

Available Sizes and Thicknesses

Mattress toppers generally vary in thickness from 2” to 4” although some may go up to 6 inches. In addition to thickness, the toppers may also be available in different foam densities, but let’s take a look at the available thicknesses and sizes.

So,the first thing you have to learn about is the availability of various thicknesses and sizes.

If you are going to buy amemory foam mattress topperthen you should consider both the thickness level and the density of a mattress topper to make sure you get the right level of comfort and support you need.

In most cases, mattress toppers are available in three basic thickness ranges: 2 inches, 3 inches, and 4 inches thick although you can also find some special mattress toppers that are 5 or 6 inches thick as well.

2 Inches Thick Mattress Topper

A 2-inch thick mattress topper is the thinnest topper available. It can introduce more comfort and softness to your mattress and give you an extra plush and luxurious feel.

You should only buy a 2” mattress topper when you have a brand new mattress and you only want to add an extra soft layer to it and make it feel a bit softer.

2” thick mattress toppers are not suitable for older mattresses as they are too thin and they won’t be able to provide the support that you need and cover sagging or other deficiencies.

3 Inches Thick Mattress Topper

The extra inch can make a big difference.A 3-inch mattress topper is a bit thicker and depending on the material you choose and whether you purchase a softer or firmer topper, it will provide you with greater comfort and support.

It can also make up for certain deficiencies in an older mattress, but this again depends on the type of a topper you choose. If you have alatex mattressand want memory foam on top, then you can use a 3-inch memory foam topper. It will make your existing mattress plusher and more luxurious or just slightly firmer.

4 Inches Thick Mattress Topper

4 inches is considered to be a maximum thickness of a mattress topperand anything thicker than 4 inches would be classed as a mattress rather than a mattress topper. However, some 5 or 6 inch thick toppers can be found as well.

A 4-inch mattress topper is ideal for covering the deficiencies of an older mattress.It will provide you with a smooth and supportive layer and a comfortable sleeping surface for a sleep without any body aches.

It is also a good thickness if you want to feel all the benefits of amemory foam mattresswithout buying one.

How to Restore and Fix a Sagging Memory Foam Mattress (in 3 Easy Steps!)

It has only been a few months, and that new mattress you spent a bunch of money on is already sagging.

First, let’s clarify something. There are body impressions and then there is significant sagging. It doesn’t take long for memory foam mattresses to form body impressions. This is a normal trait associated with memory foam. Sagging, however, is more extreme, and while most companies offer a ten-year warranty, they won’t cover minor sagging.

If you want to know how to fix a sagging memory foam mattress, you’ve come to the right place. By the end of this article, you’ll be ready to forget about this issue and get back to a good night’s sleep.

1. Use a Mattress Pad or Mattress Topper

The simplest and most effective way to solve a sagging memory foam mattress issue is with a mattress topper. While this might not be a permanent fix, it can sometimes improve the quality of your sleep.

Many folks turn to memory foam to solve lower back pain, backaches, neck pain, and for extra support. Your new bed won’t do you any good if you’re sleeping on an uneven surface full of mattress sag. Adding a mattress topper can help improve your saggy mattress.

Most mattress toppers have foam or latex mattress material, so they share a lot of the contouring capabilities of a memory foam mattress. You won’t be sacrificing any of your pressure points by going out and purchasing a good quality mattress pad.

Keep in mind that this tip will work best if you’re dealing with a mild sag in the mattress. We’re talking a sagging area of around one or two inches but anything more, and you’ll still notice a dip even with the memory foam mattress topper. If you’re experiencing any sagging more than that and you still have a warranty on your mattress, use it.

There is a bit of a difference between a mattress pad and a mattress topper. The topper is usually thicker and contains more material to create a barrier between you and the mattress.

The pad does not provide as much support, and they typically have different materials such as polyester, wool, or cotton. You’ll want to keep all these factors in mind when choosing how you plan on tackling the saggy memory foam mattress.

2. Add More Mattress Support

Sometimes you need more support to keep the mattress from sagging. From the surface, the issue might look like a mattress problem when really, it’s a frame problem. You can find all kinds of mattress support items online and in stores. These will help secure the base of the frame to provide more support to the mattress.

When you add more support, you are essentially lifting the mattress from the slats a little to create a bit of space in between. With that space, you won’t experience the mattress dipping down in between the slats. Some mattress supports will fill in the spots in between the slats completely. When you do this, you’ll usually have the best results.

Ideally, you want to fill all the gaps where the memory foam mattress may sneak through and create dips in the bed. As you lay on those dips every night and put pressure on the mattress, you’re only making the problem worse and causing more damage.

If you read the fine print on your mattress warranty, many will provide specific information about how you need to support the mattress. If you don’t follow those instructions, it will void your warranty, so they understand the importance of providing a proper base for your memory foam mattress.

3. Rotate the Mattress

If all else fails, you can always rotate or flip the mattress. Turning it will help prevent sagging in the same place. If you’ve tackled the two previous issues and you’re still experiencing sagging, it could be due to lack of rotation.

When we sleep in the same spot every day, we’re going to create a dip; there’s no way to prevent that. Whether your mattress is new or old and you sleep the same way each day, that sag is likely your own doing.

Rotating the mattress doesn’t always take care of the problem. You may find that the mattress sagging is on the other side, as well. If that’s the case, then you might want to try flipping it.

Now, there are only a few situations that would merit flipping the mattress. First, it has to be dual-sided. Many mattress companies will recommend against flipping it because the other side doesn’t offer the same benefits as the top.

For example, if you have a memory foam mattress, you likely have a comfort layer on top with support layers on the bottom. The bottom portion of the mattress will be much firmer because it’s supporting you and preventing you from sinking all the way into the mattress. If you prefer a highly firm mattress, then you might like this even better.

Keep in mind that mattresses you can flip aren’t always better. In many cases, these types of mattresses are lower quality and don’t contain the necessary components you need for support, comfort, and balance.

Now that you understand how to restore and fix a sagging memory foam mattress, let’s take a look at some more useful information you might want to know about your sagging mattress.

What Causes a Memory Foam Mattress to Sag?

Let’s say that you’re here because your mattress hasn’t sagged yet. Maybe you’re trying to prevent it in the future. Memory foam mattresses are not cheap, so it’s important to do everything in your power to preserve them. Here are some of the things that cause the mattress to sag.

Extra Weight

The thinner the mattress, the more it will sag. Most memory foam mattresses are no less than 10 inches thick, so if you have a thicker one, congratulations.

If you sleep with a partner or you spend a lot of time in your bed, you’re putting your weight on the top of the mattress. As we do this every day, we leave an indentation.

There’s nothing you can do about this unless you try to add more support to the base of the bed or use a mattress topper to try and slow down the progression of sag. Either way, all mattresses will sag over time with your body weight resting on it every day.

Even traditional mattresses like innerspring and box spring mattresses sag quickly.

Lack of Support

Every high-quality mattress you buy will come with a few different layers. The bottom layer is the support layer. This section of the mattress exists to prevent you from sinking too far in, and it helps the mattress keep its shape.

If your memory foam mattress has poor support, you’ll experience sagging faster. In this case, you need to improvise a bit. We would suggest using some of the tips we outlined above about adding more support to the base of the mattress rather than the top.

Mattress helpers are useful devices because they create a more even base for the mattress to rest. If you have a strong support system underneath the foam, you’ll experience less sagging and more longevity from your bed.

Poor Foundation

Here is where it’s important to follow the instructions and guidelines outlined in your mattress specifications. There should be instructions telling you what type of foundation and bed frame you need and how much space you can have between the slats. Generally, we find that most mattress manufacturers will say no more than three inches in between each slat.

Gravity will push the mattress down through excess space in the slats when you lay on it. The result will be premature sagging and frustration on your part.

Make sure you consult all manuals, so you know what kind of foundation you need for your memory foam mattress. We don’t recommend attempting a DIY solution for this, either. You could end up voiding your warranty.

How to Prevent Sagging in the Future

The number one best way to prevent sagging is by rotating your mattress regularly. Memory foam mattresses morph and shape to your body, so you need to keep changing the position of the mattress, so it doesn’t have too much time to take shape.

If you want, add a gel-infused memory foam topper to the mattress as an extra barrier. You’ll love the cooling features of the gel, as well.

Another helpful tip is if you’re seriously worried about sagging, you should choose a firmer foam mattress. These high-density foams won’t sag as easily because there is less space between them, and they provide more support. The best mattress, one that comes with quality materials, a sleep trial, and a generous warranty, will rarely sag on you.

Frequently Asked Questions

How many years does a memory foam mattress last?

Memory foam mattresses should last as long as ten years, depending on how you take care of them. If you’re following all the tips we’ve talked about, then you should have no problem getting ten years out of your mattress without any sag. Luckily, most mattress companies offer a ten-year warranty that will cover you against any manufacturer defects during that time.

When can you flip a memory foam mattress?

We’ve said that you should always rotate your mattress, but flipping is another issue. Unlike traditional innerspring mattresses, many memory foam beds are not the same on both sides. If you flip them, you’ll end up with a much firmer mattress on the other side. This issue may not be a problem for some, but for most, it won’t work. There should be instructions on this in the manual you received with your specific mattress.

How thick of a memory foam mattress is best?

A: The thicker, the better in terms of wear and tear. While the cost of the mattress will increase as you get up in size, so will your protection from sag. Thinner memory foam in the four to the six-inch range will sag faster because you’re putting more pressure on the mattress and base below.


By this point, you should know exactly how to restore and fix a sagging memory foam mattress. This type of mattress is comfortable, plush, and supportive, but you need to do all you can to preserve it for the years to come.

Following all the tips and tricks we talked about will help you turn that old mattress morning back into a good mattress night of rest.

Memory foam, first developed by NASA and technically known as viscoelastic foam, has become one of the most popular components in mattresses. For many people, memory foam is synonymous with comfort.

This material has earned a loyal following because of its unique characteristics; it compresses in proportion to the weight applied to it and then slowly retakes its full size. As a result, it hugs the body with tailored cushioning, contributing to significant pressure relief.

Thanks to its contouring, memory foam excels at motion isolation and doesn’t make any noise, reducing the chances that you’ll be woken up by a partner getting in and out of bed. Nonetheless, memory foam mattresses aren’t for everyone, as they have potential downsides as well.

Utilizing in-house testing and customer experience data, we’ve made a list of the best memory foam mattresses of 2020. Additionally, we’ve written an in-depth buyers guide to help you figure out a memory foam mattress is right for you

Choose memory foam if:

  • You want deep contouring and hug from a mattress
  • You share a bed and are easily disurbed by someone else’s movement
  • You are a side sleeper or have sharp pressure point

Skip memory foam if:

  • You tend to sleep hot
  • You don’t like to feel like you’re sinking into a mattress
  • You prioritize moving on top of the bed, including for sex

More and more mattresses have come on the market using memory foam layers, which has left many shoppers unsure of what distinguishes the best from the rest. We’ve simplified the process and identified the top memory foam mattresses.

Product Details

Amerisleep AS3

Who it’s best for:
  • Hot sleepers who want features to promote temperature regulation
  • Athletes and pain sufferers looking for enhanced recovery at night
  • Side sleepers and lighter-weight back and stomach sleepers

Amerisleep has built a product line of memory foam mattresses that stand out in large part thanks to their thoughtful construction and specialty cover. The AS3 is one of their most popular models and can provide excellent sleep to most sleepers.

The cover of the AS3 is one of its defining features. It is made with a specialty textile called Celliant. This material reflects heat from the body and converts it into infrared energy. Research studies have indicated that these infrared rays may help the body recuperate overnight. As a result, the Celliant cover may contribute to sleeping cooler and recovering more completely.

For the interior construction, the AS3 is made with three layers. The topmost of these is three inches of memory foam, creating a contouring sleeping surface with above-average motion isolation. The second layer is two inches of transition polyfoam using SMT technology for zoned support. The third layer is seven inches of sturdy, high-density polyfoam.

Side sleepers usually appreciate the Medium feel of the AS3 as do many back and stomach sleepers who weigh under 130 pounds. All sleepers get 100 nights to try out the mattress with the option to return it, and over the long haul, the AS3 is covered by a 20-year warranty.


Who it’s best for:
  • Sleepers who need conforming without excess sink
  • Budget shoppers who want the benefits of memory foam
  • Side sleepers over 130 pounds
  • Undecided people who want a full-year sleep trial to test a mattress

If you want a mattress that offers the benefits of memory foam but are limited by a tighter budget, the Nectar is worth a long look. This mattress features multiple memory foam sections to promote spinal alignment and overall comfort.

The Nectar has a smooth and breathable Tencel cover, and quilted into that cover is one inch of gel-infused memory foam. The second layer is three inches of memory foam that contours to the body but is a bit more firm than traditional memory foam. The third layer is another inch of gel-infused memory foam. As a combined comfort system, these layers cultivate significant motion isolation and spinal support but maintain their structural integrity instead of bottoming out or sinking excessively.

The Nectar has a Medium Firm feel that works for a broad range of people including most side sleepers, especially those over 130 pounds, as well as stomach and back sleepers who weigh less than 230 pounds.

The Nectar’s price point is lower than most memory foam beds; nevertheless, each mattress comes with a 365-night sleep trial that far outlasts those offered by most other companies. This provides an abundance of time to test it out in the comfort of your own home. Nectar also offers a lifetime warranty that covers problems that could arise with defects in materials or craftsmanship.

Novosbed first made its name in Canada but now has production facilities in both the U.S. and its northern neighbor. In each of the firmness choices, the Novosbed comes with a reliable comfort system powered by pressure-relieving memory foam.

The Novosbed is offered in three levels of firmness: Soft, Medium, and Firm. Having this selection lets sleepers in any position and weight find a model that can meet the needs of their body.

The design of the Novosbed is straightforward. The cover is made with a Tencel material that helps wick moisture for comfort cooling. The comfort system has a layer of memory foam and a layer of transition polyfoam. This comfort system effectively isolates motion while offering above-average contouring. A thicker, high-density polyfoam acts as the Novosbed support core.

Novosbed provides free shipping as a bed-in-a-box to the contiguous U.S. and most of Canada, a welcome perk for Canadian customers. The mattress comes with a 120-night sleep trial with unique terms. After 30 nights, you can request a free comfort adjustment if the bed doesn’t feel quite right. After 60 nights, if you find the Novosbed isn’t right for you, you can return it for a full refund. The mattress is backed by a 15-year warranty from Novosbed.

Puffy Original

Who it’s best for:
  • Back and stomach sleepers who weigh 130 pounds or less
  • Side sleepers who weigh under 230 pounds
  • Customers who want a robust lifetime warranty

Puffy describes the experience of their flagship mattress as sleeping on a cloud, a state of comfort and support driven by a memory foam layer in the comfort system.

That memory foam layer is two-inches thick and made with the company’s gel-infused CloudComfort foam. Customers report above-average pressure relief to assist with healthy spinal alignment, and people highlight its notable motion isolation that limits nighttime disruptions from a partner’s tossing and turning.

A second foam layer, two-inches thick and made with polyfoam, has less conforming, which keeps sleepers from sinking too far into the Puffy. A six-inch, high-density polyfoam support core creates a stable, noise-free base for the rest of the bed.

A Medium firmness feel makes the Puffy a good fit for sleepers in any position who weigh under 130 pounds. It’s a good match for side sleepers between 130 and 230 pounds because it’s plush comfort level and degree of contouring can soften impact at the hips and shoulders.

Puffy’s sleep trial lets customers try out the mattress for 101 nights with the option to return it for a complete refund. For the long-term, Puffy offers a customer-friendly warranty: it is a lifetime warranty that provides for full replacement of the mattress at no cost if a defect arises in materials or craftsmanship.

Tempur-Pedic TEMPUR-ProAdapt

Who it’s best for:
  • Sleepers who need deep contouring
  • People who want a choice of firmness levels
  • Customers who want a luxury product with free installation

One of the most established names in the mattress industry is Tempur-Pedic. The company can boast of its leading role in turning memory foam into a material for use in mattresses after it had first been developed by NASA. For customers who want a luxury memory foam mattress, the ProAdapt certainly fits the bill.

There are three models of the ProAdapt: Soft, Medium, and Firm. All of these models use TEMPUR memory foam, but different foam formulations and layers are employed in each to create a distinct firmness feel. The Firm version is preferred by stomach and back sleepers. Side sleepers and people under 130 pounds tend to prefer the Soft or Medium models.

One of the major benefits of TEMPUR foam is how effectively it contours to the body. This allows it to cradle pressure points to keep the spine well-positioned. It also isolates motion, making disruptions from movement a thing of the past.

The ProAdapt comes with free installation and removal of your existing mattress. Once it is set up in your bedroom, you have 90 nights to see how well it works for you. While you can make a return during this 90-night window, a return shipping fee of $175 is deducted from refunds. The mattress comes with a 10-year warranty covering abnormal defects in materials and manufacturing.


Who it’s best for:
  • People who want a 2-in-1 firmness design
  • Customers who prefer copper-infused foam
  • Value-minded shoppers

The Layla mattress may not have the name recognition of the famous rock song of the same name, but it’s quickly rising in popularity among mattress shoppers. With multiple twists on traditional memory foam mattress designs, the Layla delivers exceptional performance at an accessible price.

A defining feature of the Layla is its reversible firmness construction. Each side of the bed has a different firmness level with one side Medium Soft and the other Firm. On either side, you can rest comfortably on a layer of memory foam.

With the softer side facing up, the memory foam layer is three inches thick, copper-infused, and has a density of 3.5 PCF. Beneath that is two inches of transition polyfoam with Surface Modification Technology (SMT), arranging the material into zones to give reinforcement to heavier parts of the body. This foam has a density of 1.65 PCF.

The support core of the Layla is four inches of polyfoam with a density of 1.5 PCF. Beneath it is one inch of the same copper-infused memory foam used on the Medium Soft side. When used as a Firm mattress, this side faces up. A breathable cover with a ThermoGEL cooling agent surrounds all sides of the bed.

Layla customers have 120 nights to test out the mattress during a no-risk sleep trial. The mattress comes with a lifetime warranty that provides for the repair or replacement of any mattress with notable defects.


Who it’s best for:
  • Customers who want moderate bounce and contouring
  • People looking for value from a trusted brand
  • Side sleepers who weigh under 230 pounds
  • Back and stomach sleepers under 130 pounds

Casper helped prove to the world that customers were looking to the internet for a better way to buy a mattress. The original Casper mattress that powered this revolution still offers customers an excellent all-foam mattress at a competitive price.

The top layer of the Casper is 1.5 inches of an open-cell polyfoam, and the second layer is 1.5 inches of memory foam with a density of 4 PCF. By combining memory foam with a specialty polyfoam in the comfort system, Casper built a mattress with more responsiveness than many other memory foam offerings. While it’s easier to move on top of the Casper, the mattress retains its ability to relieve pressure and prevent excess motion transfer.

The third layer of the Casper is 1.5 inches of a transition polyfoam with a density of 3.5 PCF. The foam is zoned so that it holds up better underneath the body’s weightier areas. The final layer, the support core, is 7.5 inches of high-density polyfoam that serves as a noise-reducing, stable base.

The Casper has a Medium feel that typically works best for back and stomach sleepers under 130 pounds as well as side sleepers under 230 pounds.

Casper’s sleep trial lets you test the mattress for 100 nights with simple, hassle-free returns. A 10-year limited warranty provides coverage in case of a defect in materials or craftsmanship.

Who Should Buy a Memory Foam Mattress?

You should buy a memory foam mattress if you have experienced pain (either from sleeping or otherwise) , want to feel like you’re sleeping “in” rather than “on” the mattress , and/or value motion isolation to limit nighttime disruptions.

Side sleepers, who have high-impact areas at the hips and shoulders, frequently have great results with memory foam mattresses. Back and stomach sleepers, especially those under 230 pounds, appreciate these beds as well.

Memory foam is not the best fit for people who sleep hot. It may be a poor match for people who need to move easily on top of the mattress (including for sexual activity).

What to Look For in a Memory Foam Mattress

To find the best memory foam mattress, it helps to know the key things to look for so that you can keep your eye on the ball. In general, memory foam provides above-average pressure relief and motion isolation but can sleep hot and permit too much sink for some people. Manufacturers often add components to try to address the downsides, but the actual effects of those design changes are mixed.

As you review specific models, consider the following factors and how important they are for your personal decision-making

  • Price:There’s no avoiding the bottom line, and you’ll need to make sure that any mattress you’re seriously considering fits in your budget. Memory foam beds tend to cost from $800 up to $2,500, but discounts may be available with promotions or coupons.
  • Sleeping Position:Your body’s support needs will vary based on your typical sleeping position. Memory foam is a solid bet for side sleepers who have sharper pressure points. It can also work well for back and stomach sleepers if they have a lighter body weight or if the mattress is on the firmer side.
  • Contouring:Virtually all memory foam will have notable hug, but some models feature a softer foam with even more pronounced contouring. Consider how much you want to sleep “on” versus “in” the bed and then select a mattress that fits that preference.
  • Quality Materials:Excellent materials translate to more durability and top-flight performance. All foams will wear out over time, but low-end memory foam will start to sag more quickly, reducing its support and comfort.
  • Firmness Level:Every person has their own preferred mattress firmness, and it’s critical to look for a mattress that fits that preference. As a general principle, side sleepers and people with lower body weight lean toward softer mattresses.
  • Motion Isolation:You should expect good motion isolation with memory foam, but not all of these mattresses are created in this regard. If you’re extremely sensitive to sleep disruptions, look for a bed with more contour and greater motion isolation.
  • Pressure Relief:Pressure relief is a standout feature of memory foam because it can give each part of the body the cushioning that it needs. If you have major pressure points, make sure to look for a memory foam bed with a thick enough comfort system to prevent bottoming out through the foam.
  • Ease of Movement / Sex:Memory foam has minimal bounce because of how slowly it retakes it shape. This can make it hard to move on the bed, including during sex, and can cause some people to feel stuck in the mattress. If this is a concern for you, look for a memory foam mattress with more mild contouring.
  • Edge Support:With its characteristics of compression and lack of bounce, edges tend to be a trouble area for memory foam mattresses. The foam sinks more around the edge, which can be problematic for people who want to sleep or sit near the perimeter of the mattress.
  • Temperature Regulation:When it contours to the body, memory foam can cut off airflow throughout the mattress. Further, the foam itself retains heat, making it even softer and further restricting airflow. Some mattresses have features to try to decrease heat buildup, but hot sleepers should be aware that even newer memory foams with various infusions will still tend to sleep hotter than other mattress materials.
  • Noise:A loud mattress that squeaks when you move on it can be both annoying and disruptive. All-foam mattresses are extremely quiet, making them a great choice for noise-sensitive people.

How Does it Feel to Sleep on a Memory Foam Mattress?

If you’ve never tried out a memory foam mattress, it’s natural to wonder what it feels like. While words can’t explain it perfectly, this section gives you an idea:

  • Floating on Clouds:With a more plush, cushioning feel, customers often describe memory foam as what they envision it’s like to “sleep on a cloud.”
  • A Big, Warm Hug:Memory foam conforms to the body, providing a hugging sensation that can be comfortable but can also cause heat retention.
  • Totally Unmoved:When you’re on these mattresses, you’ll be almost completely unaffected by movement that happens on the other side of the bed.
  • Under No Pressure:Pressure relief from memory foam can reduce impact at parts of the body where you might be used to feeling pain or stress.
  • In One Place:With little bounce, you may feel more settled or even stuck in one place on a memory foam mattress.

What are the Different Types of Memory Foam?

All forms of memory foam have shared characteristics, but not all memory foams are the same. The feel, durability, and performance can be different depending on the composition and type of the foam as well as its quality.

Traditional Memory Foam

Traditional memory foam offers the most classic performance of this material. It has deep contouring and motion isolation along with notable heat retention and minimal bounce.

Both its benefits and drawbacks are easily detected, and as a consequence, this type of memory foam is controversial. Some people love its cloud-like hug while others complain about feeling stuck in the foam or overheating on it during the night.

With newer memory foams on the market, traditional memory foam’s use has declined slightly, but it can still often be found in the comfort system of all-foam and hybrid beds.

Plant-Based Memory Foam

The manufacturing process for memory foam involves a handful of chemicals, some of which are derived from petroleum. In a plant-based memory foam, sometimes called a “bio” foam, a certain percentage of those petrochemicals are replaced with products that come from plant matter, such as soybean oils.

Plant-based memory foam is appealing for eco-conscious customers, but it is important to note that the plant oils replace some but not all of the petrochemicals.

Because the rest of the manufacturing process is similar, the performance of plant-based memory foam is similar to other types. It may come with a slightly higher price tag than petroleum-based memory foam.

Gel-Infused Memory Foam

Gel-infused memory foam intersperses a gel material into the foam itself. The gel can be added in a swirl pattern or can be enclosed in small beads that are distributed through the foam.

The goal of infusing gel into memory foam is to try to reduce heat retention. The gels often have properties that are designed to absorb heat from the foam, keeping heat from building up near the sleeping surface and around your body.

Gel-infused foams are common and, depending on the gel used, may provide a modest decrease in heat retention. That said, even these memory foams will heat up more than other mattress materials.

Copper-Infused Memory Foam

In this type of memory foam, copper-filled beads are intermixed with the foam. These beads are intended to draw heat away from the surface of the mattress. Copper has antibacterial properties, which may help prevent odors and the deterioration of the mattress.

Many products that include copper are marketed as having health-promoting effects on circulation or muscle recovery. To date, there’s limited evidence that copper gel in a mattress has any direct positive or negative effects on individual health.

Memory Foam vs. Hybrid

A great deal of mattress shoppers find themselves deciding between a memory foam or hybrid mattress. Hybrids are built with a coil-based support core and various layers, including sometimes memory foam, layered above the coils.

The following table compares memory foam and hybrid mattresses. As you review it, keep in mind that the performance of hybrids has a wider range because of the multitude of ways that their comfort system can be built.

How Much Does a Memory Foam Mattress Cost?

The typical price range for memory foam mattresses goes from $800 to $2,500, but there are options with price tags above and below that range. A number of factors can influence the cost of these beds:

  • Thickness of the memory foam layer:If there are more layers or thicker layers of memory foam, the mattress will likely have a higher price.
  • Density of the memory foam:Mattresses that use high-density memory foams tend to be pricier, but they also normally last longer.
  • Where it’s made:Mattresses made in the USA tend to be more expensive than those made in China or other countries.
  • Extra features:Specialty design elements or materials can push up the price of a memory foam mattress. For example, textiles to fight heat buildup or the use of organic materials can add to the cost.

Even for higher-end models, there are often discounts or promotions that can give customers significant savings from the sticker price.

Memory Foam Density and ILD

Many mattress manufacturers list the specifications of the foam employed in their mattress. Two of the most helpful specifications are density and indentation load-deflection (ILD).


Density is measured in pounds per cubic foot (PCF), which is calculated by weighing a 1 foot by 1 foot by 1 foot cube of the foam. For memory foam used in a mattress comfort layer, 3.5 PCF is about average. Higher density memory foam is usually 4-5 PCF.

The density of the foam can affect the feel, but not all high-density foams are firm. Instead, the biggest impact of density is on longevity of the mattress. Higher density usually correlates with a longer lifespan. Additionally, high-density foam generally recovers its shape slower, giving it that slow-responding feel traditionally associated with memory foam.

Indentation Load-Deflection (ILD)

ILD provides an indication of how easy it is to compress the foam. It is measured with a special device that applies force to the foam until it reaches a certain level of indentation. The higher the ILD, the firmer the foam will feel. For a broad sense of what ILD numbers mean,

  • 10-12 ILD: Soft
  • 12-14 ILD: Medium
  • 14-16 ILD: Medium-firm
  • 16-18 ILD: Firm

You can look at listed foam ILD to get a sense of how a mattress may feel, but keep in mind that a mattress is made with multiple layers, each of which plays a part in the overall feel and performance. In addition, not all companies calculate ILD in the exact same way, so ILD alone is not always a reliable way to assess mattress firmness.

How Long Will a Memory Foam Mattress Last?

Most memory foam mattresses last from six to eight years before having issues with sagging or diminished performance. This lifespan is longer than most innersprings and airbeds, similar to hybrids, and shorter than all-latex beds.

Some memory foam mattresses may last for more or less than the 6-8 year average. Issues that can affect longevity include:

  • Quality of materials:Memory foam layers that are thicker, denser, and part of a mattress made with significant attention-to-detail are far more likely to hold up for the long haul.
  • Stress placed on the mattress:More stress is placed on a mattress by couples than an individual person, by people with a higher body weight, and by children (or pets) who jump on the bed.
  • Mattress maintenance:Failure to use the mattress as intended can make it susceptible to more rapid wear-and-tear. For example, an unsupportive frame may heighten the risk of premature damage to the mattress itself. Using a mattress pad or protector helps protect the mattress against spills that could damage the foam.

Higher-end foams tend to cost more, but that investment often pays off over time. Opting for better materials and then taking care of the mattress can contribute directly to a longer useful life for your bed.

Last Things to Consider With a Memory Foam Mattress

Now that you’ve got a strong base of information about memory foam mattresses, there are only a few other issues to cover to round out your knowledge.


When a foam mattress is made, certain volatile organic compounds (VOCs) are created, and those become sealed in when the mattress is compressed and prepared for shipping. As a result, when it is first installed, the mattress can “off-gas” those VOCs. There is no health risk from this, but it can cause an unpleasant odor. This smell is temporary and should fade within a few hours to a few days, especially if your bedroom is well-ventilated. This issue doesn’t affect overall satisfaction for the majority of customers, but if you’re extremely sensitive to smells or VOCs, a foam mattress may not be the best option for you.

Sleep Trial Period

A sleep trial is a way of describing the return window for a mattress, and it lets you test out the bed in your own home to make sure that it is the right fit for you. Because you can’t feel them out before buying them, most online mattresses come with a risk-free trial of 100 nights or more, and we advise buying a product that comes with this type of return policy.

Adequate Bed Support

Your mattress is just one part of your bed; another part is your bed frame. Make sure that the frame you use is in accordance with the mattress warranty. This enhances performance and keeps your warranty valid. If you don’t already have a quality frame, include the cost of a new one in your budget.

Appropriate Bedding

Bedding is another aspect of setting up your bed that is worthy of your consideration. For example, breathable sheets or a lighter comforter may be helpful if you buy a memory foam mattress and are concerned about sleeping hot. You also want a quality pillow that works in conjunction with your mattress to promote spinal alignment.
