How Long Do Mattresses Last? The Results May Shock You!

Mattresses are pretty expensive — one quick glance at our buyer’s guide will confirm this fact. This is why many people do not replace them – not even after many years of use.

They do not want to spend a lot of money on a new one. Besides, now you can delay the process of buying a new one if you do an excellent job at maintaining your existing one.So, how often should you replace your mattress?

It doesn’t matter which type of bed you have. Most of them are ready for replacement within ten years to ensure a good night’s rest (old mattresses can hurt your sleep quality). Besides, it can last beyond ten years on average, if the owners maintain it properly.

Also, many different factors affect a bed’s lifespan. You can extend its life expectancy by following a few easy steps in the text below. We prepared and wrote down some tips to boost its longevity.

You’ve been sleeping on your mattress for a few years now, and you start to notice squeaky springs, sagging foam, or you just plainhurtwhen you get out of bed. If this describes your sleeping situation, it’s probably time for a new bed. And if your mattress is around 7-10 years old, it’s definitely time to consider a new mattress.

The goal when buying a new mattress is to find one that will hold up under wear and tear, stay supportive no matter your sleeping position, and of course, give you a good night’s sleep. The longest-lasting mattresses are not necessarily the most expensive or “luxury”— you can typically tell how long a mattress will last based on the type of mattress, the material quality, and the warranty.

When Should You Replace Your Mattress?

If you’ve been sleeping on your mattress for a while, you might not notice that it’s causing you to sleep poorly. In fact, most people are so used to the way their mattress feels, they get accustomed to an unhealthy sleep posture without realizing it. That’s why when you buy a new bed, it feels a little awkward and maybe even a little bit uncomfortable in the first few weeks you use it (also known as the “adjustment period”).

Sometimes an easy way to tell if you need to replace your mattress is if you get much better sleep elsewhere— in a hotel or maybe even on the couch. Other telltale signs include:

  • Significant sagging or dips in the surface (while you’re laying in bedandwhen there’s no pressure on it at all)
  • Squeaky coils (in innersprings or hybrid mattresses)
  • Coils that poke into your back or side (you can feel them through the comfort foam layers)
  • Feeling “stuck” or trapped in the mattress

The Lifespan of Different Mattress Types

You can read mattress reviews from customers to get some idea of how long a mattress will last, but the truth is you won’t know for sure until you try one out for a few years! But this is risky— a mattress is a big investment, and you most likely don’t want to spend a few hundred or thousand dollars on one only to find it breaks down after just a few years.

Thankfully, you can typically get a general idea of a mattress’s lifespan by choosing a certain type made of quality materials. Enough data exists that we can now pinpoint when different mattress types will begin to break down (on average).

Mattress TypeAverage LifespanSigns of Wear
Innerspring5-6 yearsSagging, coils poking through, worn or flattened comfort foam layers, noisy coils
Memory Foam7-10 years

Softening, sagging, losing supportLatex Foam8-12 yearsSoftening, sagging, losing supportHybrid5-7 yearsSagging, coils poking through, worn or lumpy comfort layers, noisy coils

Innersprings

Of all the mattress types, innerspring mattresses have the lowest customer satisfaction rating because they sag so quickly. Typically any mattress with coils will sag faster than one without, but some mattress brands use wrapped coils to mitigate this issue. Wrapped coils, also known as Marshall coils, have better motion isolation than the typical Bonnell or continuous coil, meaning they absorb movement on the mattress. This helps prevent the pillow top from sagging, at least for a little while.

One of the signs that an innerspring is beginning to deteriorate is that it causes pain— in fact, the best mattress for back pain is typically a memory foam or latex bed. Despite their softness, they are also quite responsive and offer support without sacrificing comfort or inflaming pressure points.

Memory Foam

Memory foam mattresses are becoming one of the more popular types because they pair with bed in a box mattress brands perfectly— thanks to their soft, viscoelastic feel, they compress easily for shipping and then expand to their original shape after unboxing.

Memory foam beds are well-liked because they have great pressure relief, conform closely to the body, and they’re virtually noiseless. They isolate motion better than most other mattress types, too, so they’re a good option for restless sleepers.

The most common complaints surrounding memory foam mattresses have to do with their construction— memory foam is pretty dense, and as a result, it traps heat. It’s also made with petroleum, which can produce an off-gassing odor when the mattress is opened— however, most of the time, this off-gassing smell goes away after a while. If you’re concerned about your memory foam bed trapping heat or having a smell, choose one made with cooling foams or plant-based foams (like the Bio-Pur® in all Amerisleep mattresses).

Latex

Latex foam mattresses are not as easy to find compared to the other three types, and they’re also more expensive, but for some people, the extra work and cost of getting one are worth it. Natural latex foam is hypoallergenic, antibacterial, and made using eco-friendly methods. On top of that, it can last up to 15 years— longer than any other mattress type.

Not all latex beds are all-natural, though— blended and synthetic latex beds feel similar to natural latex, but they are made using different chemicals instead of rubber tree sap. A high-quality latex mattress should have a dense, firm support layer to prevent sagging.

Hybrids

Many hybrid mattresses are made with wrapped coils, but you’ll notice their lifespan is not much longer than innersprings. People choose hybrids over innersprings because they contain thicker comfort foam layers and they often have wrapped coils. They’re essentially a combination of memory foam and innerspring mattresses in one mattress.

How Can I Extend the Life of My Mattress?

The best way to ensure your mattress lasts as long as possible is to practice a little prevention. Always place a mattress protector or encasement on your bed as soon as you get it; this will keep out bed bugs, dust mites, and liquid stains or spills. Any or all of these things can void your mattress warranty, which you might need if the mattress shows signs of sagging during the warranty period.

To maintain a quality mattress, it’s more about what youdon’tdo to it than what youdo:

  • Don’tuse it on the wrong foundation: innersprings are the only types of mattresses that need box springs. If you use a hybrid, memory foam, or latex bed with one, you risk damaging it. Of course, check the brand’s website for specific foundation recommendations, but don’t just put your mattress anywhere. A low-quality bed-frame can make your mattress deteriorate faster as well, so invest in one with sturdy slats or a platform base.
  • Don’tsleep on your mattress without a mattress protector or encasement. An encasement covers all six sides of your mattress while a protector only covers the surface. We recommend a waterproof, bed-bug proof encasement if you can get one. Encasements also keep allergens, mildew, and dust mites out of your bed, which can negatively affect your sleep or lead to an infestation.
  • Don’tsleep on a mattress with low weight capacity. Most mattresses are built to support most body weights and types but always double-check. Obviously, the amount of weight compressing the mattress will affect its lifespan, and if you’re sleeping on a bed that’s not built to support your weight, it’s sure to sag and become unsupportive before long.
  • Don’t skimp on cleaning your mattress.Proper mattress care is relatively low-maintenance, but it’s worth it to keep your sleeping space hygienic and clean. Regularly wash your sheets, mattress cover (if it’s removable and washable), and encasement. You can also spot-clean and deodorize your mattress using vinegar or baking soda.
  • Don’t buy a mattress without a warranty.A warranty safeguards you against sagging and indentations below a certain depth (usually 1 inch or more). It also comes with protections against manufacturing defects, such as bunched foam, broken coils, or ripped mattress covers. The standard mattress warranty lasts 10 years— if your warranty lasts less than that, it’s a sign to look elsewhere. Since most mattresses last around 10 years, you’ll want protection for at least as long as you own the bed. Additionally, the warranty can give you an idea of how long a company stands behind their product.

How Much Should A Durable Mattress Cost?

As you begin to shop, set a budget of around $1,000 for a queen-size mattress— be careful not to fall for cheap, promo beds made with low-quality materials. Conversely, don’t feel like you need to spend thousands of dollars on a “luxury” mattress made with gold threads or hand-tufted buttons since these features don’t add any comfort or support to the mattress.

Replacing an Old Mattress

Perhaps after reading this, you’ve realized it’s time for a new bed. The best mattress will come with a standard 10-year warranty and be made of supportive, high-quality bases, and durable, resilient foams. Additionally, you should try one that comes with a sleep trial because this will allow you to try out the bed for 30-90 nights and return it for a refund if you don’t like it. Bottom line: your sleep quality should not suffer because your mattress quality is subpar.

Does a firm mattress last longer?

Because softer mattresses contain more layers of foam, they’re known to sag a bit more than firmer, thinner beds. However, don’t think just because you’ve chosen a soft mattress it won’t last. Always choose a mattress with a highly durable support core— this will deter sagging no matter how soft or firm the top layers are.

How long should a mattress last?

It depends on the mattress type, but most beds last between 5-10 years.

Will a mattress topper help?

We use mattress toppers for various reasons, but most of the time it’s to add some extra comfort to the top layers of our bed. Sometimes people buy a topper to extend the lifespan of a mattress, thinking it will “cover up” sags and thus make the bed more supportive and comfortable. While this is true for a little while, a topper can only do so much for an old, supportive mattress.

If your mattress is causing you pain, a topper won’t help for long. We recommend investing in a new mattress as soon as you can.

How Long Does A Mattress Last? When Is It Time For A New One

Table of Contents

It is usually pretty easy to tell when it’s time to replace an innerspring mattress because they become squeaky, less responsive, and may even start to poke you in areas where the coils have worn down considerably. However, with all of the different materials and innovative mattress designs available on the market today, it can be hard to remember what we should expect from your mattress as far as its lifespan is considered. So we ask the question, how long does a mattress last?

Many different mattress companies are offering warranties with their products that can last for 10 years, 20 years, or even a lifetime. This has often made me wonder, can a mattress last 10 years? Can a mattress last 20 years? I highly doubt they can last a lifetime. Considering people spend a third of their lives in bed, on average, this just didn’t seem possible to me. So if you are like me and have also asked yourself the same questions, continue reading to find out what I learned!

The Lifespan of Your Mattress

Not all mattresses are alike, but even the most durable mattress will not last forever. The expected lifespan of different types of mattresses relies on a few factors.

First, we will discuss the different types of mattresses individually because the material used in construction largely determines the lifespan overall.

After that, we will examine the traits that should be considered regarding the lifespan of all types of mattresses.

This combined information will enable you to make an accurate assessment and determine if it’s time for you to upgrade your current bed, or not.

1. The Materials Used

The most important thing to consider when evaluating the mattress lifespan is, what materials were used to to make the mattress? Different materials deteriorate faster than others.

Ultimately, this is the key trait to think about when asking “How long does a mattress last?” When comparing memory foam vs spring or any other material used, the type of mattress you have will reveal the most accurate estimate of how long it will last.

a. How long does a memory foam mattress last?

We recommend replacing your memory foam mattress after no more than 10 years.

Memory foam was invented by NASA to sustain extreme force and high levels of pressure. As a result, it is extremely durable and makes an excellent shock-absorbent material that is usable in many different products, like mattresses.

When purchasing a memory foam mattress, it is important to keep the thickness and density of the foam in mind. A higher density will provide a more durable level of support. A density level of 3.5 to 4 lbs./ft³ will provide the support necessary for most people. If you are a heavy person or have a large frame, aim for a density level of 5 lbs./ ft³ or more to prevent premature wear and tear.

You will know it’s time to replace a memory foam mattress when it starts to sag and show an indentation of greater than 2 inches. It will also be less responsive and take longer to decompress after years of extended use, alerting you to the end of its healthy use.

b. How long does a latex mattress last?

We recommend replacing your latex mattress after no more than 10 years.

Latex mattresses are very durable and will last you a long time, especially if you get one with a high-density level. Natural latex is more durable and has more elasticity than synthetic latex so it will typically last longer. Synthetic latex mattresses are more affordable so you may want to consider hybrid latex options that blend both types to provide the consumer with a lower price.

Some latex mattresses open up with a convenient zipper and you can replace the top layer which will allow you to lengthen the bed’s lifespan by several years.

You will know it’s time to replace your latex mattress when it sags, loses its resiliency, or becomes uneven on the surface.

c. How long does a pillow top mattress last?

We recommend replacing your innerspring mattress after no more than 8 years.

Generally speaking, a pillow top or an innerspring mattress will need to be replaced more frequently than other types made from foam or latex. The individually wrapped coils inside tend to wear unevenly causing large dents and sagging after continued use, especially if you always sleep in the same location on the mattress.

If you prefer innerspring mattresses, often they are more affordable, get one with a higher coil gauge. The higher the gauge number, the thicker the coils. Thick coils denote longer-lasting durability and a firmer feel overall. Another way to maximize the lifespan of an innerspring mattress is by purchasing one with a pillow top or euro top on it. This will provide an extra layer of comfort and prevent premature sagging to some extent.

2. Frequency of Use

Second, consider how often the mattress is used. The majority of people spend every night in their bed. However, if you are considering replacing a mattress in a spare bedroom, or if you travel a lot, you will want to consider how often it gets used. If it frequently is empty then it will last for many years longer than the mattress you sleep in every night.

Couples who do not live together and frequently spend time sleeping at their partner’s house should add some additional years to their bed’s lifespan. Of course, this could pose other issues which we will address in the next section.

3. Body Type and Number of Sleepers

Third, consider your body type and whether or not you sleep with a partner. If you have a large body type, are tall, or overweight, how long you should keep a mattress will noticeably decrease. The more pressure that is applied to the mattress, the faster it will start to show wear and tear. The materials deteriorate as they are used and the more pressure that is applied, either by yourself or with the additional weight of your partner, the faster it breaks down.

The breakdown of materials happens the fastest in the top comfort layers. They are the softest and most responsive layers but are unfortunately the most susceptible to compression and deterioration from excessive weight as well. When this happens the inner layers of the mattress may remain firm and supportive but without the top comfort layer or layers functioning properly, you will start to notice some of these negative side effects over time: improper back and spine alignment, less comfort, decreased pressure point relief, and increased firmness overall.

If you have a large body type or are overweight, you may want to consider purchasing the best mattress for heavy people as these cater specifically to your requirements. Buying a more specific mattress will enable you to keep it for much longer without sacrificing comfort or longevity.

4. Maintenance

Fourth, look back and consider how you care for your mattress. The amount of effort you spend caring for your mattress will also affect the lifespan. I know it seems pretty obvious but most people could increase their mattress cleaning regimen in multiple ways to help boost the longevity of their mattress. The more you clean your mattress and preserve the original integrity of the materials, the longer it will serve you before it starts to show natural wear and tear.

Make Your Mattress Last Longer

Here are a few easy things you can do so your mattress lasts longer. Take a look at these easy tricks that you may, or may not already be doing which will ensure you are giving your mattress the best opportunity to perform on a high level, and for an extended period.

  • Use a mattress protector, especially if you have kids.Preventing liquid from penetrating the inner layers of the mattress will keep it clean and prevent rapid degradation of the materials.
  • Wash your sheets frequently.They serve as a barrier which protects the mattress from dead skin cells and spills.
  • Don’t eat in bed.I know you think you can be careful but don’t test it. It can be very difficult to get food completely out of the material on your mattress.
  • Don’t let your pets sleep in your bed.Instead, get them their own. There are many reasons why pets shouldn’t be allowed in your bed. An example is that pets can drool and shed which only adds to the breakdown of materials while simultaneously creating an odor that is near impossible to get rid of.
  • Clean and deodorize it.Sprinkle baking soda on the surface of your mattress occasionally, let it sit for about 30 minutes to an hour, and then air out or vacuum it up. The baking soda will naturally extract and absorb and moisture from within and leave it smelling fresh.

How Long Does A Box Spring Last?

Do box springs wear out? They sure can! For the most part, you will know if your box spring wears out because the frame will give and no longer provide your mattress the even support it needs to maintain comfort. Often it will drastically sag on one side or in a particular corner leaving you with a slanted surface that is no fun to sleep on. If a box spring gets wet it could develop mold or bacteria which is another sure sign that it is time to dispose of your mattress and replace it. You can try to air it out but if it is not dried fast enough, then it might need replacing. You can simply get a different kind of frame like a platform bed that is functional without the need for a box spring.

Signs That You Need A New Mattress

Now that you know the estimated life expectancy of the most common types of mattresses, it’s important to remember that these are just guidelines. Regardless of what the estimates say, there are a few signs you should look for that will indicate it’s time to replace your old mattress.

Let’s have a look at some signs that mean you need a new mattress:

  • Sagging, lumps, and/or indentations:If your old mattress has visible sagging, indentations greater than 2”, or it becomes lumpy you should consider upgrading to a new one.
  • Sore and achy muscles:If your muscles and joints are sore or ache in the morning that is a good sign it’s time for a new mattress.
  • You sleep better in another bed:If you find you sleep better in another bed, like in a hotel or at a friend or lovers, it could be a sign you need a new mattress.
  • Poor quality of sleep:If you wake up feeling tired and less refreshed than normal because your quality of sleep is poor it could be time to get a new mattress.
  • Water damage:If your mattress gets wet you will most likely need to replace it. With some mattresses, you can air it out or it can be dried out in a rapid fashion so you can avoid replacement but often this is not the case. Small spills can usually be cleaned up but wet mattresses are said to be the best breeding ground for bacteria and mold which can be harmful to your health so it should be taken very seriously.

In Conclusion

How often you should buy a new mattress depends on what type you have, and how you choose to use it. Aside from the most determining factor, the material used, you must also consider how often you use the mattress, whether or not you sleep with a partner, your personal body size, and the amount of effort you spent on preventative care like light cleanings and frequently washing your sheets.

So, how long does a mattress last? Generally speaking, our best guess is about ten years, minus some years for the variables previously outlined in this article. Most often, it will be easy for you to notice changes in your mattresses integrity and overall structure that signal it will not last for much longer.

The most important thing is that you get a good night’s sleep and wake feeling rested and rejuvenated in the morning. If this ceases to be the case and you have had your bed for a long time, it’s most likely time to purchase a new mattress.

How Long Does A TempurPedic Mattress Last? (Explained)

Everything you need to know about the durability and lifespan of TempurPedic beds.

Categories:
Last Updated:

If you’ve read any of our buyer guides, you probably knowwe expect a quality mattress to last you about 8-10 years. Of course, there are a ton of factors that go into how durable a mattress will be, like your body weight, volume of use, its construction, the quality of materials inside and much more.

An overhead look at the TempurPedic Pro Breeze mattress

If you think about it, a mattress that’s sitting in your guest room will probably last longer than the mattress you sleep on with your loved one every single night. Also, a $300 mattress that sources low density foams from overseas is way less likely to hold up as long as a premium $2,000 mattress that’s made right here in the USA. But in general, a good mattress that’s used consistently should last you about a decade, give or take a year or so.

Hybrid Mattresses vs Foam Beds

Above we briefly touched on how mattress construction can have an impact on its durability, and that’s especially true if you’re dealing with a hybrid mattress. A hybrid bed is simply a mattress that contains both foam and coils, and those coils play a big role in the prevention of sagging. Not only docoils provide more support compared to dense foams, but they also provide bi-directional resistance to pressure when you lay down.

A look at the construction of the TempurPedic Tempur-Adapt hybrid mattress

Accordingly, if you’re looking to use your next mattress for as long as possible, we think you should spring for a hybrid mattress (pun intended). TempurPedic sells all-foam beds, as well as hybrid ones. You can check out full reviews of the TempurPedic hybrid beds here.

TempurPedic Mattress Warranty Analysis

The warranties mattress companies offer can sometimes be a dead tell for how long they expect their products to last. In TempurPedic’s case, theyoffer a 10-year “full replacement limited warranty.”

A 10 year warranty is pretty standard in the mattress industry. That’s what most companies offer. There are only a handful of brands that actually go above and beyond the 10 year period. For example, Nest Bedding and Layla are two companies that back their mattresses with lifetime warranties.

The Layla mattress comes with a lifetime warranty

For the most part, the TempurPedic warranty is pretty straightforward and normal. It essentially covers any manufacturing defects for a 10 year period. For example, thewarranty covers indentations (sagging) more than 0.75″, cracks and splits in the foam and defects related to the zipper. The warranty does not cover physical abuse such as burns, cuts, liquid stains or damage stemming from the use of improper bed frames. We recommend you check out all the details related to the warranty on the company’s official website.

The company also recommends you keep proof of purchase documents in a safe place. That way, you won’t run into any issues in the event you want to make a claim.

What Actual Customers Say

As your trusted bedding reviewers, we felt an obligation to get down and dirty and research what actual customers of TempurPedic had to say about the durability of their mattresses. We went through literally hundreds of reviews dating back several years looking for folks who specifically mentioned how long their mattress lasted.For the most part, people had great things to say about their beds. Below are a few reviews that might be of interest to potential customers. We didn’t include their entire comments for brevity’s sake, just a brief snippet to get the point across.

  • Customer from Portland, OR said “My original TempurPedic mattress was great for 18 years.”
  • Customer from Philadelphia, PA said they had just purchased their “second TempurPedic mattress in 12 years,” and they had “no complaints” after sleeping on their new Breeze Hybrid for a few months.
  • Customer from Hammon, LA said they purchased a king size bed 14 years ago and “they can’t imagine replacing it any time soon.”
  • Customer from Cornelius, NC said “I adored my TempurPedic for 15 years.”
  • Customer from New York, NY said they only started to “experience back pain” after they had their TempurPedic “for 12 years.”
  • Customer from Cocoa Beach, FL wrote “first one lasted 10 years.”
  • Customer from CDA, ID said they had their TempurPedic “just over a year, love it”

We could keep going, but we think you see the pattern here. And for the record, all of these reviews were from this year. The folks who claimed their TempurPedic was long-lasting kept their bed for an average of 10-15 years, which is a little longer than your standard mattress.

There were a total ofthree negative reviews we could find:

  • Unhappy customer from Houston, TX said her and her husband had their TempurPedic for “over a couple of years, and there were indentations where my husband and I sleep.”
  • David from Texas said his TempurPedic “doesn’t hold up” and that it “does good for 6 months, but doesn’t support after.” He also claimed to have a “¾” dip in the side of his mattress.”
  • Unhappy customer in Carmel, IN said it was “great for one year,” but now they’re “going into year 3 and it’s worn.”

However, based on the majority of these reviews, most people claimed their TempurPedic mattress lasted them over a decade. Just please, for the sake of a good night’s sleep, don’t be like that guy from Oregon who kept theirs for 18 years. No matter how good a mattress is, you should probably bite the bullet andpurchase a new bed after 10-12 years.

How Long Do Memory Foam Mattresses Last?

Table of Contents

Thelifespan of a memory foam mattress dependson the type of memory foam, number of layers, thickness, and density of layers, foundation layer properties, and construction strength.There are three types of memory foam namely the traditional, air cool, and gel. Traditional type is more suited if your body mass index is higher than normal and you want firm support for your spine and body. Gel memory foam has thetherapeutic propertiesfor healing lower back pain and aligning the spinal cord in a straight line. Air foam is forcontrolling your body temperaturewithin standard values and cooling your skin.

How Foam Density Effects The Life of a Mattress?

Density is a measure of weight per cubic foot. Low-density mattresses support 1.5LB per cubic foot. Medium density mattresses support 2-3LB per cubic foot. High-density mattresses can support 4 to 6 LB per cubic foot or even more. They have a high resistance to stress factors. It is because they distribute your body weight across the length X width and depth through the other supporting layers. Hence, the stress on individual layers will be relatively less.

Tensile Strength

Tensile strength is a measure of stretching limits. It is directly proportional to the elongation threshold when your body weight is placed on it. High-density mattress elongation could be hardly 10% to 15% of its original dimension. Medium density mattress elongates to 25%-30% of its original dimension. Low-density mattress elongates to 40% or more. Hence,reaching the breaking point takes more time for the high-density mattress compared to the other two types.Here, our research has been focused only on the memory foam layer. When it is supported by others like comfort layer, transition layer, spring layer, and base layer, elongation probability of memory foam layer gets reduced further. Hence,it can carry more weight per cubic foot and last longer than the other two types.

ILD Rating

Weight required for compressing 4” memory foam by 25%. Higher ILD rates can mean more weight capacity and extended lifespan.It also means the mattress is firmer in its construction.It also means the mattress can support your body weight without sinking in. However, it may not be practical to keep this factor always high since it can affect softness factor. Hence, the modern mattresses have introduced an additional layer of Gel memory foam over the polyurethane (PU) memory foam. ILD rating of gel foam is relatively low. But it transfers the weight onto the PU layer. Gelprovides softness for your body, while PU provides firmness. Combination of these two factors increases the comfort level while sleeping.

Rebound Pressure

It is called resilience. You might have seen children jumping and dancing on memory foam mattress in your home.They bounce on the mattress due to the rebound pressure offered by the foam.If this factor is higher, pressure relief points on the mattress can work more efficiently. Me top two memory foam layers can carry weight without experiencing an excess of stretching. It can also mean better body contour support which in turn increases coziness and comfort factors.

Thermal Conductivity

Heat absorbing gel memory foam mattress doesn’t retain it with its layers. It is due to increased risk of rupture within a few years. So, the design principles follow two methods of dissipating this heat.Transfer to the base layer or conversion into another form of energy for providing pressure and pain relief for your body while you sleep.The first form of transfer puts extra stress on the base layer. It can transfer heat onto bed frame if it is made of metal. When placed on a wooden bed frame, the heat gets trapped within the base layer. Since it has no way of retaining it longer, it transfers heat back to the top layer. This type of thermal circulation can also significantly reduce the lifespan of the mattress.

Hence,the best method is to convert heat into energy for pain and pressure relief.The sectional memory foam mattress consists of many horizontal sections from head to your feet. It can transfer the heat to the feet and legs section to induce faster and deeper sleep. Hence, the heat gets utilized. It also transfers part of the heat to the abdomen and hips section.If you sleep on back posture, it can help relieve lower back pain.Gel memory foam uses this heat for relieving the stress and eliminating fatigue factors from your body.

Shock Absorption

Low-density mattress can absorb shocks from abrupt posture change only for short duration. Then the cells start breaking down. You may have to change the foam layer frequently. Our experiments with a body weight of 198LBs and above showed significant differences in reaching breakdown point with time.High-density memory foam mattress with multiple layers can absorb shock better.By keeping the rebound pressure high, it is possible to reduce the impact of shocks on the foam layers.

Foam Construction

By increasing base foam thickness to 6” it is possible to provide better support for your body while resting. Transition foam of 3” and memory foam of 3” with gel memory foam of 3” thickness can increase the lifespan of mattresses at least by 5 to 6 years. It is not only due to weight distribution, but also support for different sleeping postures. If you are a side sleeper,the top gel memory foam can adjust its cells around your body to give you maximum support and comfort.PU foam can distribute your body weight around your body with spinal cord acting as a balancing point. Hence, the probability of losing your balance and changing to a back or stomach posture will be almost zero.

If you are a back posture sleeper, the density of PU memory foam will be higher, while the density of gel memory foam can remain the same. This sort of construction can also increase lifespan. If you happen to be a stomach sleeper,the thickness and density of transition and comfort layers have to be more.We have considered the BMI factor from an upper limit of the standard range to the low to high obesity levels. Practical experiments have shown that any mattress which can support higher BMI can certainly extend its support for normal BMI also.

Preventive Maintenance to Increase The Life of Your Memory Foam Mattress

The finest range of quality memory foam mattresses can have a long life when you can follow certain simple preventive maintenance procedures.They can protect your mattress from mold and mildew, dust and dirt, germs and microorganisms.Maintenance keeps your mattress free from moisture and dampness due to sweating.
