The Definitive Guide to Buying a Mattress

Shopping for a mattress has never been easier if you’re armed with this info.

Replacing your mattress can be exhausting. Navigating the stores and websites, debating between foam and springs, and determining how much to spend can leave you feeling like you need a good nap.

Instead, skip the stress and follow these tips from Lexie Sachs, Senior Textiles Analyst at the Good Housekeeping Institute, that will help you navigate the world of mattresses.

Where to Shop for a Mattress

Laying down in the store isn’t the only way to go anymore. New mattress-in-a-box companies have won over thousands of customers with convenient shipping and free trial periods. Online mattress buying has seen a serious boom, but it’s not right for everyone. Here’s what you need to know.

Shop in the store if.

Go the traditional route ifyouwant a greater variety and to feel them before buying.In a mattress store, you should never pay full price. Always shop the sales, and don’t be afraid to negotiate with the salesperson. Most stores will also offer removal of your existing mattress. The downside is it can feel overwhelming and it’s harder to compare prices to know if you’re getting a good deal. A big mistake is rushing the decision by quickly lying down on many different mattresses to find the one that feels best. If you’re going to invest in a mattress,take the time to recline for a while (at least 10 minutes)and make sure you don’t feel any pressure or pain.

Shop online if.

This newer route offers agreat alternative if you have trouble making decisions, since there are fewer options. Plus, you can shop from home!These mattresses generally arrive in a box at your doorstep within a few days and include free shipping and a money-back guarantee (even if you simply don’t like the mattress!) so there’s minimal risk. Online, the price is usually final, but it doesn’t include markups for being sold at a physical store. The downsides are that you typically have to set it up yourself and deal with getting rid of your old mattress.

Either way, always ask about the return policy.Not happy with your pick? You may get a partial refund if you bought it in a store, but online companies often arrange to pick it up for a local charity and will give back 100% of your money. Make sure you can test out a new mattress for a month risk-free; that way, you can get used to it before making a decision.

The Best Mattresses You Can Buy Online

The name Casper is synonymous with "mattress-in-a-box." Itsfour foam layers range from soft to firmto offer comfort and support, which our testers loved (especially the under-40 crowd). There’s both a less expensive version (with less layers) and a pricier one (with more).

Tuft & Needle was priced lowest among its competitors, but still stands out as atop mattress on Amazon. This simple model has two layers of foam: a firm, support layer on the bottom and a cushy, cooling layer on top. Our panel particularly liked the friendly customer service.

Unsure if you need a soft or firm option? This foam style gives you both: Justflip the mattress to change the support level. It has copper built-in to help keep you cool and avoid the overheating that is typically associated with memory foam.

Fill out a survey about your sleep habits, andHelix builds a "custom" mattress for youwith layers of foam, latex, and microcoils. They can even personalize each side, so you and your sleeping partner don’t have to fight about which mattress to get.

How to Choose Your Perfect Mattress

There are three common types of mattresses:innerspring, foam, and adjustable. There’s no one "right" material to choose, but in general, side sleepers need a softer mattress, stomach sleepers need a firm one, and back sleepers fall somewhere in between. Beyond the types of mattresses and firmness, you’ll need to think about a few other factors. From sleep style to negotiating with a bedfellow, here’s what to look for based on your needs:

If you like a bed with bounce

Traditional innerspring styleshave that familiar bouncy feel and may be firmer. Interconnected coils are extra-durable, but individual "pocketed" coils, each covered with fabric, reduce the ripple effect that happens when someone on one side of the bed moves.

If you prefer a firmer base

Memory foam optionshave less spring and offer more pressure relief. To determine quality, look at the density and thickness of the foam, which will determine how deep you’ll sink. The newer, online mattresses generally use several different layers of foam, with heavier ones on the bottom for support and lighter, cooler kinds on the top for comfort.

If you want a plush top

Innerspring mattressestypically have either a fiberfill or foam outer layer, covered in quilted ticking. But even if you want an uber-plush feel, don’t be swayed by a thick-looking pillowtop as it can compress over time. It’s often best to choose a firmer, well-quilted mattress, and then cover it with a replaceable mattress topper.

If you like to change it up

Consider anair-filled mattress, like Sleep Number, which has a remote that controls how much air is inside. Two side-by-side chambers allow you and your partner to customize the mattress firmness separately. There are also foam mattresses (like the ones from Layla) with soft and firm sides, so you can just flip it over as needed, and modular designs that let you move around the springs on the inside.

If you sleep on your side

You’ll want a surface that will support your body weight, and conform to your shape.Innerspringsmay have more pressure relief than some foam or latex mattresses, but asoft foam mattressor one with built-in pressure relief points around the shoulders and hips can work for side sleepers, too

If you sleep on your stomach

The last thing a stomach-sleeper probably wants is an enveloping memory foam — it would feel smothering! Instead, a firmer bed will provide the best support. Consider afirm foam, dense innerspring, or air-filled mattress.

If you sleep on your back

You’ll wantsomething in the middle— a surface that supports, but has some give so your spine is kept in a healthy alignment. You’ll find happiness with any of the mattress types, but you should do your best princess-and-the-pea impression to see what feels best to you.

If your partner tosses and turns all night

Consider aninnerspring mattress with pocketed coils, or memory foam, latex, or a dual-chamber air-filled mattress. Medium-firm picks will all have good "motion isolation." But remember, these models could actually be less comfortable on the body of a restless sleeper, as there’s little forgiveness against one’s movements.

If you and your partner’s preferences don’t match

Theair-filled mattresses with dual chamberscan help, or check out the online mattress company Helix. Each person can fill out a questionnaire and have a side customized based on the responses.

If you sleep hot

Manufacturers can get carried away with claims about cooling properties, especially when you consider all the layers (protectors, toppers, sheets, and so on) that go on top of the mattress. That said,foam or latexcan hold in body heat, especially if they’re very soft and a lot of your body sinks in. Newer technology helps alleviate this issue and you can always accessorize your bed with toppers and sheets that offer cooling benefits.

If you have allergies

Foam and latexare both inherently antimicrobial and resistant to dust mites and mold. If you opt for innerspring or air topped with fiberfill, be sure to encase it in an allergen-resistant cover to keep irritants at bay.

If you have back pain

Memory foam and/or latexis best for those with back pain since it molds to your body for support.

If you’re concerned about chemicals

Look forfoams certified by CertiPUR-USas well as certifications for other materials like GOLS for latex or Oeko-Tex for other fabrics to feel more confident about your purchase.

If you can’t decide what matters most

Some savvy manufacturers make ahybrid-style mattressthat combines the buoyancy of an innerspring core with the motion isolation of memory foam. It’s a best-of-both-worlds option that can satisfy many partner disputes and sleeping styles.

How to Choose a Mattress Topper?

Sometimes mattresses can’t provide you with the level of comfort you need. It can be perhaps because your mattress is too hard, you wake up frequently because your partner moves around too much, or maybe you just can’t get enough comfortable.One great option is to get a mattress topper for your bed.

It can be a great way to revitalize your bed as it will provide you with extra support and extra cushioning and it will not cost you as much asbuying the new mattress.

There are different types ofmattress toppers, so it can be difficult for you to determine which one would work the best for your specific needs and sleep preferences. You might find it hard to decide what material to buy, what thickness is right for you, how much to spend, etc.

Some of the most popular types of mattress toppers arememory foam, latex, cotton, wool etc. With some careful research you will be able to get the right one that will give you what you need at a more than a reasonable price.

In this article, we will take a look at the pros and cons of each type of material and at some of the key factors which can help you bring your decision easier.

Key Points to Consider

With so many different mattress toppers, it can be hard to choose one for you, so you should decide what exactly you need from a topper first, then figure out what material will best meet your needs.

Here are some of the key factors you should take into consideration:


A higher price doesn’t necessarily guarantee the mattress topper would be better for you personally. You should look for one that will meet your needs and not simply buy the most expensive you can afford.

Support and Comfort

If you prefer a firmer feel and you like extra support for your back and limbs, then you should opt for a latex topper.

However, if you prefer a softer feel and a topper that will cradle your body and relieve pressure points, thenmemory foam topperwould be perfect for you, or a topper made of naturally soft material such as down or cotton.

Thickness and Density

Mattress toppers vary in thickness from 2 to 8 inches.If you have a firm mattress and you are looking for a topper that would relieve your pressure points and allow you to sleep on your side, or if you weigh more than average, then you may need to look for thicker options.The materials with the best range of thicknesses are memory foam and latex.

The density of a topper determines how much support it will provide you.Here again, memory foam and latex mattress toppers usually have the largest choice, allowing you to find just the right level of comfort that you need.

Motion Transfer

Memory foam and latex mattress toppers are also good at reducing the transmission of movement between you and your partner. So if you sleep with arestless sleeper, whose tossing and turning might keep you awake, these toppers are good options.

Sleeping Hot

If you are looking for amattress topper that will sleep cool and keep you comfortableall night long then you should avoid those made entirely of memory foam as memory foam tends to retain the most body heat.

Latex is known for its natural cooling properties, so latex mattress toppers would be good choice as well as those made of down, wool and feather.The latter are good all year round as they will keep you warm in winter and reduce heat retention in summer.

The cover of the mattress topperalso plays a huge role insleeping cool, so you should opt for those toppers with covers good at wicking away sweat.

Also,the thickness of the toppers can determine how hot or cool they will sleep, and those thicker toppers usually sleep hotter than thinner ones despite the attempts of manufacturers to add some special cooling elements like cooling gel or ventilation tubes.


Also the toppers made of certain materials are better for allergies while other are also more resistant to dust mites, bed bugs, mold and mildew.

Ease of Moving and Cleaning

Be aware of the overall weight of the mattress topper before you proceed to buy it.Remember that you need to remove it from the packaging, put it on the bed and remove it at least once or twice a year for cleaning.

While down, feather and cotton are easier to move thanmemory foamor latex, they are far more difficult to clean.

What Type of Material to Choose

Mattress toppers come in a range of different materials and stylesand it’s important to know what you hope to gain from using a topper and what are the pros and cons of each material.

Memory Foam

Although memory foam mattress toppers can be a bit expensive, they are a popular choice as they perfectly contour to the specific curves of your body, absorb movement and noise.

Memory foam toppers alsooffer a lot of thickness choices, so you can easily find the level of comfort and support you need.Memory foam will conform to your bodyand provide you with a supportive and relaxing surface to sleep on. It will also reduce the amount of motion transfer and noise.

These toppers also come in varying densities.A density of most of them ranges between 2 and 6+ pounds per cubic feet.The toppers of higher density memory foamwill usually cost more, but they will provide much better support for the body and longer-lasting conformity.

If your memory foam mattress topper has adensity of 3 pounds or underper cubic feet, it will feel softer and be less supportive than those of higher densities. It will allow your body to sink into it faster than toppers of higher densities. They are also lightweight and easier to transport.

Memory foam mattress topperswith a density of4 to 5 poundsper cubic feet work well for most people as they provide a good balance of comfort and support.

Toppers with a density of6+ poundsper cubic feet are the best for people who have medical needs and are in need of a high level of support for the body. They will slowly conform to their body shape and weight and provide a good support much longer than those with the lower densities.

The major downside of memory foam mattress toppersis that they are made of a synthetic material that can have a bit of off/gassing but that usually dissipates after a few days.

Besides this, memory foam will retain body heat more than some other materials. So, if you tend to overheat during the night it is better to look fora breathable memory foam mattress topper.


Latex mattress toppersare the most expensive option, but like memory foam toppers,they can provide excellent comfort and support.They can provide comfort and relieve pressure points by making your mattress harder or softer. They feel firmer than memory foam, but are still soft enough to provide you with a comfortable night’s sleep.

Besides this,toppers made of 100% natural latex are also antimicrobial, non-allergic and more durablethan any other type of a mattress topper.Latex toppers offer a wide range of thickness and support options.

Like withmemory foam mattress toppers, these have some disadvantages too. As we have already mentioned, they can be very expensive due to the complicated nature of latex production. They may not be perfect for people who are allergic to latex.

Wool is a natural material, and wool mattress toppers can be a bit expensive too.Wool is also one of the most durable materials, and yet it is soft and comfortable.It is particularly suitable for those who suffer from allergies and can even keep bed bugs away from your mattress.

That’s why wool mattress toppers make a wonderfully luxurious addition to your mattress and they will also keep you cool in summer and warm in winter and wick away any excessive moisture.

There are some bad sides with toppers of this material as well. They can be more expensive than other toppers made of other materials and they may not provide the same cushioning as memory foam.

Down or Feathers

Toppers made from goose or duck feathers, or even softer and more luxurious down are perfect for those looking for a soft and comforting feel.

They are also good at reducing motion transfer between partners and at regulating heat in the summer and winter. These toppers are very durable as well and will last for several years.

However, if you are allergic on feathers or you need a firmer topper, these may not be the right choice for you. They may not be thick enough to disguise an old and lumpy mattress and may need fluffing to keep their shape.

Cotton and Polyester

There is a wide range of mattress toppers made from polyester and cotton and they also range in price.Polyester toppersare very affordable.

The advantages to cotton and polyester mattress toppers are that they are very easy to maintain and are good for those looking for a softer feel, but they are not so durable like the toppers made of some other materials.

Egg Crate Foam

Mattress toppers made of the egg crate foam are the cheapest option available.They are very lightweight and easy to transport. They also provide good cushion, but may not be durable and great forback support.

Just like memory foam, egg crate foam has some off-gassing smell and can retain body heat and sleep hot, especially during the summer months.

How to Pick the Right Memory Foam Mattress

Are you thinking of getting rid of your innerspring mattress to make room for a new memory foam mattress? Before you commit to a new bed, there are some things you need to know. You don’t want to spend one-third of your daily life trying to sleep on a lemon and the rest of it walking through life a sleep-deprived zombie.

A new memory foam mattress is a major purchase. The search for the right one should be taken seriously, especially if you’ve never slept on one before. Memory foam mattresses receive really high approval ratings from consumers compared to innerspring mattresses, which means there’s a good chance you’ll be happy with your new bed. Eighty-one percent of memory foam mattress owners report being satisfied with their purchase versus just 63% of innerspring owners, according to review website

With such high satisfaction rates across a broad price range, memory foam mattresses have much value potential in general. They are known for reducing pressure, relieving pain and improving motion isolation. If you shop well, you could improve your sleeping and feel better through the day for years to come.

All About Memory Foam Mattresses and How to Find Your Match

Memory foam was developed by NASA researchers to help keep astronauts comfortable during flights. A few decades later, memory foam mattresses came on the scene and now have become nearly as ubiquitous as their spring-filled counterparts. Unlike innerspring mattresses, memory foam mattresses do not rely on metal springs for support. Instead, they consist entirely, or nearly entirely of polyurethane and viscoelastic foam.

Memory Foam Types

Not all memory foam mattresses are the same. They are available in three different types. What the memory foam is made from determines which type it is. The three primary types of memory foam mattresses are:

  • Traditional memory foam: Essentially the same petroleum-based material developed by NASA in the 1960s with a few improvements. This is characterized by high temperature sensitivity, meaning it feels firmer when cool and softer when warm. This property yields a foam with slow responsiveness.
  • Gel memory foam: Like their traditional petroleum counterparts with gel added to the foam to help improve heat retention. Gel memory foam tends to be a little faster to respond to movements than traditional foams.
  • Plant-based memory foam: Memory foam created from a proportion of natural plant materials to be healthier, cooler and more environmentally-friendly. This material results in temperature-neutral foam with fast responsiveness.

Density & Firmness

Within these different mattress types are varying densities, firmnesses and mattress constructions.

Memory foam density is measured in pounds per square foot, and refers to the amount of polymers versus air in the foam. A denser foam can feel firmer, especially with temperature sensitive types, but the more important difference between densities lies in durability and support capabilities.

Memory foam mattresses often have layers of foam of varying densities. More dense layers are usually on the bottom for support and the foams of lesser densities are on top for initial comfort.

Typically, mattress foams rate within 1-8 pounds per foot, with lower rated foams feeling softer and less supportive. A lower density foam (less than 3 lbs) provides less of the characteristic “floating” feeling while higher density foams prove better at cushioning pressure points. However, there is such a thing as too dense. Mattresses with memory foams over 5 lbs can feel more difficult to move on (slower recovery) and more prone to sleeping hot.

The base layer of foam, sometimes called the core, is also compared by density. For regular polyurethane foams, densities under 1.5 lbs are considered lower quality, and result in a mattress that may feel unsupportive or be prone to impressions. Foams in the high-resiliency range (1.8 lb to 2.4 lb) are generally considered good quality.

As a rule, denser foam is more expensive and tends to last longer. Cheaper mattresses with shorter lifespans often have low foam densities. These mattresses can feel great for a few months, but usually show signs of wear early.

Considerations for Different Types of Sleepers

Sleep position can have an effect on the firmness level you prefer. Take this into consideration:

  • Back sleepersneed more support than side sleepers, but a mattress that is too firm will push back against the spine or leave the lower back unsupported. A medium-firm mattress is good for this type of sleeper.
  • Side sleepersneed a softer mattress to relieve pressure on the hips and shoulders. Soft to medium mattresses with thicker comfort layers allow the body to sink in to accommodate curves and keep the spine straight.
  • Stomach sleepersneed a firm mattress that keeps the torso from sinking too deep, causing the spine to be misaligned. Firm to medium firm beds will likely be best.
  • Combination sleepers, or those who sleep in different positions, need to have a mattress that is neither too stiff and nor too soft. A medium-firm mattress with a thicker comfort layer will give a little for side sleeping, but be firm enough for stomach sleeping.

Heavier people should pay attention to the thickness of their mattress because it is a major factor in owner satisfaction. In reviews, mattresses less than 12 inches thick show dramatic differences in comfort and satisfaction for people weighing over 250 pounds. Beds over 12 inches and with thicker layers of memory foam are more likely to offer comfort.

Memory foams can change their properties as their temperature varies. Your body heat will decrease the firmness of the mattress in places where you touch it long enough for temperature-sensitive types of foam. This is intentional, but you should be mindful of it. If you are trying mattresses in a cold showroom, the mattresses may feel more firm, and vice versa.

Memory foam also tends to soften slightly over time as the mattress breaks in, so this is something else to keep in mind when shopping. Remember, you can always add a topper for more softness, but it’s hard to make a bed firmer.

Pros and Cons of Memory Foam Mattresses

Memory foam mattresses became very popular in a short amount of time. Now, they share a significant portion of the total U.S. market. These mattresses have a lot to offer consumers, greatly expanding choice and comfort options.

As with any product, there are both positive and negative qualities with memory foam mattresses. We’ve compiled a list of the pros and cons of memory foam mattresses so you know what you are getting into, and what to compare when shopping. Not all memory foam mattresses will possess the qualities we disclose, but enough of them do to warrant mentioning. These statements give an overview of memory foam mattresses in general, but keep in mind brands and types can differ.

Pros of Memory Foam Mattresses

Motion Isolation– The ability of memory foam mattresses to keep motion localized is one of their most popular attributes. Unlike typical innerspring mattresses, memory foams allow one person to be less disturbed while the other is moving, a significant benefit for couples.

Pressure Reduction– Memory foam mattresses provide even support that reduces the amount of pressure on one area by spreading weight across the surface of the material. Instead of springs producing many single points of pressure along the sleeper’s body, memory foam contours along the body, compressing in heavier areas and supporting lighter areas.

Pain Reduction– Nearly across the board, users of memory foam mattresses report reductions in back and shoulder pain.

Longevity– Memory foam mattresses made with quality materials tend to last longer than innersprings as they resist impressions longer. Their durability is one of their major selling points. Mattresses with higher foam densities tend to last longer than those with lower densities.

Cons of Memory Foam Mattresses

Heat Retention– The most common consumer complaint about memory foam mattresses is the amount of heat many of them retain. There have been several solutions to help combat this including gels and plant-based foams. This is an issue for about 8% of people overall.

Off-gassing– Traditional and gel memory foams are made from petroleum byproducts, and all mattresses can contain harsh glues and other additives. Volatile Organic Compounds are gasses that are emitted from some substances. They have been linked to numerous health effects, including cancer. Odors reported by consumers are reflective of the amount of chemicals a mattress is letting off. Manufacturers and retailers typically advise consumers to air the mattress out prior to use. About 15% of memory foam owners report strong initial odors overall.

Weight– The densities of foam required to support a person while sleeping can weigh a lot. While memory foam mattresses can be heavy, not many people consider this a problem since they don’t necessarily need frequent rotating and never need flipping.

Memory Foam Mattress Comparisons for 2019

Memory foam beds arrived on the scene in the early nineties with only one brand available to consumers. Now, there are many memory foam mattresses to choose from on the market, offering people a wide variety of features.

What qualities are you hoping to find in a mattress? How much can you spend? What qualities are you willing to forgo to adhere to your budget? These are questions you should have answers to before making a decision.

Below is a table of some popular mattresses available on the market currently. Some of their characteristics are listed along with their cost and a customer satisfaction rating. Rates of satisfaction are based on customer reviews. Take a look at what is out there to get your search started:

As you can see, these mattresses are as varied as the people who use them. There are plenty of choices, but don’t allow yourself to experience analysis paralysis. Too many options can overtax your senses and make reaching a confident decision difficult.

Buying a Memory Foam Mattress

Traditional, gel and plant-based memory foam mattresses all have great attributes, although each is different. Think about the qualities you want to find in a mattress when weighing options.

You can find some great potential for value with many traditional memory foam mattresses. One of their biggest complaints is from consumers who feel they sleep hot. Off-gassing is another major complaint with many different lines and models. All petroleum based mattresses need to be aired out for some time. For the most part, though, owners report satisfaction with traditional memory foams.

Gel memory foam mattresses are marketed to combat heat-retention issues in foam mattresses. Though many models demonstrate some improvement in regards to temperature, many consumers still find gel mattresses sleep hot. Off-gassing remains an issue with gel memory foam mattresses also. These mattresses tend to slightly sleep cooler than traditionals, but don’t get caught up in the hype some companies create around their gel. Factors like density are still important to overall quality and comfort.

If you are an environment or health conscious person, plant-based memory foams are a good choice, and a more affordable alternative to latex. Off-gassing is much less of an issue with foams made from significant percentages of plant oils. Consumers report these memory foams sleeping cooler than traditional foams and some people prefer the more responsive feel. Plant-based materials are more sustainable than petroleum products as well.

There are many things to consider when looking for a new mattress, but knowledge and research are two of the best tools for getting a good value and a comfortable mattress. Read reviews and talk to a variety of retailers about your potential purchase. There is information out there. Take your time and you’ll make a purchase you’ll be happy with for years to come.

How to Choose a Memory Foam Mattress

How do you choose a memory foam mattress? Very carefully.

Memory foam mattresses are afast-growing alternativeto innerspring mattresses because they contour to the body and provide excellent comfort and support.

We know a thing or two about memory foam, our natural memory foam mattresses are some of the best ranked in the world.

4 Tips to Choosing a Quality Memory Foam Mattress

Knowing what to look for is key in finding the best memory foam mattress to fit your needs. Here are a few important things to know before buying a memory foam mattress:

1) Ask About the Foam Density

The misconception.densityis what dictates thefeelof foam. That’s not entirely true.

Foam density actually has more to do with the foamsdurability. A 5 pound per cubic foot memory foam mattress will outlast a 3lb memory foam by an average of 10 years.

Most high-end mattresses, including Essentia and Tempur-pedic, have 5lb+ density foams. See how we compare to other memory foam.

Buyer Beware: Many mattress companies boast a 5lb memory foam butfail to specifythat this dense foam only makes up the 1st inch of the mattress. The following layers are weak 2 or 3 lb density memory foams.

2) Know the mmHg!

mmHg is basically how comfort is measured.

It’s the unit of measurement used to determine a mattresses reaction against pressure.

According to the healthcare industry, a standard of 32mmHg or lower is considered pressure relieving.

More pressure relief = less press points = less tossing and turning which is the goal here.

A low mmHg also means better blood circulation, however, this is difficult to achieve while maintaining a higher density.

The best rating in the industry is offered by Essentia mattresses with 12.43 mmHg.

3) What does ILD (Indentation Load Deflection) Mean

A mattress ILD, or indentation load deflection, ranges from 6 to 40. Most memory foam mattresses on the market rate anywhere between 10 and 16 ILD. Many of the best memory foam mattresses use multiple layers, each with a different mmHg, which enhances a mattress’ comfort because the layers work together.

4) Find out Where the Mattress is Made.

Mattress components are often imported from foreign countries like China and assembled in Canada or the U.S.A. Many mattress companies deceitfully claim that their products are Made in Canada or Made in U.S.A. when in reality they are just assembled in that country.

Tests are rarely performed on mattress components that are imported and as such there is no way of knowing what chemicals are used to make them. Any harsh chemical odors are masked prior to product exportation withindustrial perfumesor even green tea extracts.

Natural Memory Foam – vs – Regular Memory Foam

Regular memory foam, also known as visco-elastic memory foam or visco foam, is made with petroleum-based chemicals including those fake plant-based memory foam mattresses.

This type of memory foam is synthetic (man-made) so it sleeps hot because it traps in body heat like nylon or polyester fabrics do.

Sleeping hot and chemical odors are the main complaints among memory foam mattress owners.

It’s all due to the chemical composition of that foam.

If you’re not a fan of sleeping hot and are health conscious, you’ll want to consider natural memory foam mattresses + pillows.

You may have seen us on Dr.OZ, Rachael Ray, O Network along with other media appearances. It’s next generation memory foam which sleeps cool, is comfortable and durable all the while maintaining a healthy sleep environment. See how they’re made.

Some people swear by memory foam mattresses, but they don’t suit everyone. If you’re tempted by one of these mattresses, you’ll need to think about which type you want and how much you’re willing to spend. Otherwise you might end up a dud that you’ll wish you could forget.

Memory foam mattresses, also known as memory mattresses, are topped with a layer of temperature-sensitive viscoelastic material (memory foam). This type of mattress is good at relieving pressure on painful joints, but is usually pricier than sprung mattresses.

Memory foam mattresses feel very different to lie on than regular sprung mattresses. This means memory foam mattresses aren’t for everyone – some of you have said that you find memory foam mattresses too hot. But those who like memory foam seem to love it – as one owner told us: ‘my memory foam mattress is the most comfortable mattress I’ve ever had.’

Read on for more advice about memory foam mattresses. If you know you want one already, go straight to our mattress reviews.

Memory foam mattresses mould to your body shape

Memory foam is affected by room temperature, so you might find the memory mattress cold and hard when you first go to bed. As it reacts to your body heat, it moulds to your shape – this can make it more difficult for you to move or get out of bed compared to other mattress types.

Memory foam also reduces air circulation around your body, which makes the memory foam mattress feel warmer. Many people find this helpful in winter but you may feel too hot in summer.

If you usually use an electric blanket, it’s important to note that many manufacturers say not to use one with memory foam, as it’s a potential fire hazard. But as a memory foam mattress is warmer, you shouldn’t miss it. If you do, go up a tog on your duvet or add an extra blanket.

Memory foam mattresses generally can’t be turned over. But you can turn them around, and some mattresses have handles which make this easier to do.

Memory foam mattresses are the second most popular type of mattress among Which? members. Nearly a quarter of the members we surveyed about their mattress had bought a memory foam one.

Memory foam-only mattresses

Most memory foam mattresses are actually sprung mattresses with a layer of memory foam on top. Some, however, have extra layers of memory foam instead of springs. These are often described as pure memory foam, or memory foam-only, mattresses.

They tend to be pricier and softer, but not necessarily better – some pure memory foam mattresses impressed in our tests, while others were poor.

Memory foam mattresses can cost more than £2,000, but our independent tests show that you don’t always get what you pay for. If you’re set on memory foam but can’t afford to spend thousands of pounds, we’ve found several cheaper options worth considering.

In fact, we’ve found two Best Buy memory foam mattresses for under £400 – this is fantastic value for money. One has a spring core with memory foam on top, while the other is pure memory foam – great if you want a slightly softer mattress.

Memory foam mattress toppers

If you’re not quite sold on a memory foam mattress, but fancy getting a feel for the how the foam moulds to the shape of your body, you may want to consider buying a memory foam mattress topper.

It won’t make your mattress any more supportive, but it may make it more comfortable. Four in five mattress topper owners told us that their topper had made their mattress more comfortable, when we surveyed more than 1,000 Which? members in April 2017.
