Memory Foam: Pros and Cons

Considering a memory foam mattress or similar product? Read what sleep experts say about it.

Few things feel as good as a good night’s sleep. That’s especially true if sleep seems to escape you, night after night after night.

If you’ve heard about memory foam, you may wonder if it could improve the quality ofyoursleep. Some people swear by it. Others are less enthusiastic.

What exactly is memory foam? And what are its pros and cons? Here’s information to help you decide whether memory foam is worth a try.

What Is Memory Foam?

First designed in the mid-1960s for NASA airplane seats, memory foam is made from a substance called viscoelastic. It is both highly energy absorbent and soft.

Memory foam molds to the body in response to heat and pressure, evenly distributing body weight. It then returns to its original shape once you remove the pressure.

In addition to protecting against impact, these properties make memory foam very comfortable. After its "virgin flight" for NASA, memory foam made a foray into other applications. For example, it was used as cushioning in helmets and shoes. Medicine found a use for it in prosthetics and products to prevent pressure ulcers such as seating pads for people who are severely disabled.

Then, memory foam really took off. It’s now well known for its use in pillows, mattress pads, and mattresses, which come in different densities and depths.

What Are the Benefits of Memory Foam?

Could the special properties of memory foam enhance your sleep? Sleep specialist Donna L. Arand, PhD, says that objective studies supporting the claimed benefits of memory foam — or the effects of any particular type of sleeping surface — are lacking.

This is true for a variety of reasons, she says. This type of sleep study can be expensive, if conducted independently. Or it is "chased" by a shadow of bias, if supported by industry.

Also, some sleep technology, such as memory foam, is relatively new, so it hasn’t been well studied. But perhaps one of the more difficult stumbling blocks to testing the health benefits of mattresses such as memory foam is the subjective nature of sleep. It is simply difficult to measure.

Sometimes the brain’s electrical activity, measured with an electroencephalogram (EEG), and other findings recorded during a sleep test don’t always match up perfectly with a person’s subjective experience, says Arand, who is the clinical director of the Kettering Sleep Disorders Center in Dayton, Ohio. "They might say, ‘I had a great night’s sleep,’ but the EEG parameters might not really indicate that."

Sleep is not only subjective, but preferences for sleep surfaces are individual, Arand says. "There’s quite a bit of variability between individuals in terms of what type of surface — whether it’s firm, hard, or soft — they prefer when they’re sleeping," she says. "As far as we know, there is no rhyme or reason for that."

Many of Arand’s patients who use memory foam have offered unsolicited glowing reports like these about memory foam: "I’m sleeping great." "Best sleep I’ve ever had." "I love going to bed at night." Arand says these anecdotal responses may be one-sided. That’s because she and other staff don’t ask all their patients about their sleep surfaces. "We may only be hearing the good stuff," Arand says.

Kathy R. Gromer, MD, sleep specialist with the Minnesota Sleep Institute in Minneapolis, agrees that memory foam may improve sleep. "It can, if it relieves painful pressure points," she says. But Gromer adds that memory foam doesn’t do anything for sleep apnea or other sleep-breathing disorders — and sleep disorders are the primary complaint of most her patients.

"When you lie on the memory foam, the heat from your body softens it in appropriate points," Arand says, "so this helps to support your body along the curves and natural lines of the body." Memory foam manufacturers claim this helps relieve pain and thereby promotes more restful sleep. And, though consumers often believe that very firm mattresses are best, more "giving" mattresses like these may lead to better sleep in people with back pain, according to the National Sleep Foundation.

Although there aren’t scientific data to support the hypothesis, Arand wonders whether memory foam sleep surfaces might be especially helpful for older people. For them, minimizing extra movement could reduce the number of times they awaken during the night. Being less aware of a bed partner’s movements might be an extra benefit, she adds. "Without the coiled springs, you feel your sleep partner’s movement less, and that might help, too."

What Are the Disadvantages of Memory Foam?

Gromer says that memory foam products may retain body heat, which could make them less comfortable in warm weather. However, Arand has not heard this complaint from her patients. "In our culture, most people can adjust their thermostats or blankets for the appropriate season," Arand says.

When new, memory foam can produce an odd chemical smell — a phenomenon called offgassing. To minimize this problem, the Sleep Products Safety Council, a sleep products trade group, recommends airing out the mattress or pad for at least 24 hours before putting sheets on it. "If you follow directions, the smell dissipates quickly," Arand says, "But I’ve never heard of anyone having reactions to it."

Are Memory Foam Products Safe for Young Children?

"I would strongly recommend avoiding this and similar very soft materials for use in infants’ beds," Gromer says. "That’s because soft bedding traps [carbon dioxide] and increases the risk of sudden infant death syndrome (SIDS) deaths."

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.

How Long Does a Memory Foam Mattress Topper Last?

A mattress topper is a bedding item designed to be used on the top of your mattress to provide extra comfort and support, improve cleanliness, and prolong the lifespan of a mattress.

Toppers can be made from various materials such asmemory foam,latex, down, etc. and there are many different designs and structures that can suit different needs and sleep preferences.

Your topper should improve the support for your entire body and complement any sleeping position. It should also act like an extra cushion for your entire body, especiallymemory foam mattress topperand allow you to sink into it to prevent the appearance of pressure points and provide you with the peaceful and restful sleep every night.

However, if it causes you to wake up in pain or felling more tired than ever, then it may be that your mattress topper is getting old and that you should get the new one.

Read our article and learn more about memory foam mattress toppers as well as when and why you should replace them.

How Long Does a Memory Foam Mattress Topper Last?

You would think thatmemory foam mattress topperscan last as long as the beds made of the same material, but this is not the case.

The average lifespan of mattress toppers, including those made entirely of memory foam, is 3 to 5 years.This is only the case with high-quality mattress toppers, whereas those made of cheap materials will only last a year or two.

The longevity of a memory foam mattress topper will depend on other factors as wellsuch as the weight being put on it, frequency of use, the thickness of the topper, the condition of your mattress, and how well the topper is maintained.

Overweight

Heavier people may speed up the process by adding extra pressure to the memory foam topper.Memory foam mattressesusually contain a highly resilient core and high density base that make the top memory foam layers more durable, but the topper doesn’t have this.

Extra weight can also cause the open cells to crumble quicker than they would do under an average person.

Thickness

The thicker the topper, the longer it will last.Thinner toppers usually wear out quicker, while the thick memory foam will last longer as it takes longer to break down over time, and it will also provide greater comfort.

The Condition of Your Mattress

As toppers are generally laid over an existing mattress, if the mattress underneath is old and in a poor condition; if it is already worn out and sagging in places, your memory foam topper will simply follow that contour and make the sage even more pronounced due to its soft and contouring nature.This will eventually ruin your mattress topper.

If your mattress looks like new, but you still experiencepainwhile sleeping, even with the new memory foam mattress topper placed on top, then you still may need to replace the mattress.

If your mattress is over 7 years old then it’s time for a new one, even if it doesn’t show any signs of a long use such as cracks, sagging, protruding wires, etc. because, like we have already mentioned, an old and uncomfortable mattress will decrease the comfort of your memory foam mattress topper and shorten its lifespan.

Frequency of Use

Memory foam mattress toppers in guest bedrooms will last significantly longer than those used every night.

The reason why toppers don’t last so long in bedrooms is because they are used a lot more than toppers in guest bedrooms. Spending 6 to 8 hours a night on them each night puts a lot of pressure on them which is why they wear out faster than those mattress toppers used on beds in guest rooms.

Maintaining Your Mattress Topper

Memory foam may be difficult to clean and maintain, butthere are ways how you can clean them and prolong their lifespan.

You should clean them at least once or twice a year by vacuuming them, spraying them with water and detergent solution, washing them, spot cleaning or using topper covers and washing these regularly.

Well maintainedmemory foam mattress topperswill last longer and serve your better than those that are not maintained at all.

If you avoid cleaning your topper, stains from food or drinks, pet urine, dust and accumulated debris and odor will eventually ruin your topper and render it useless.

Memory foam – pros and cons

Visco elastic foam or "memory foam" is a very different material and perhaps partly because it has such unusual qualities compared to the many other materials used in mattresses, there is also a lot of misinformation "disguised as fact" about it. It is also subject to many different "formulas" in its manufacturing by different companies which change its qualities . for better or for worse . and this too becomes the subject of lots of the hype and misinformation you will hear in the world of marketing and selling mattresses.

What are the basic differences in materials used in a mattress?

There are two basic ways that a material in a mattress reacts to weight and pressure.

1. Viscous materials tend to flow away from pressure like a liquid or honey and tend to distribute and absorb energy

2. Elastic materials tend to store energy under pressure and to different degrees push back against compression

Materials like Water and Air, are viscous.They do have some pushback in a mattress enclosure but this comes from the elasticity and resilience of the enclosure or from other materials in the enclosure that holds them not the air or water itself. Viscous materials can be very hard initially with sudden pressure but feel much softer under more gradual pressure (try leaping onto an airbed or waterbed core). This is because viscous materials take time to "give way" to pressure. When they do give way, they give way in any available direction (out to the sides for example) and spread the pressure out through the layer.

Springs and non memory foams (like "normal" polyurethane and latex) are elasticand will recover quickly and with different amounts of "force" behind them (based on how quickly they spring back) to their original shape or length. Both are also breathable enough that the air just goes in and out with little to no resistance in either direction (compression and recovery) so the response from both of these are mainly because of the material itself not from what encloses them (although this will also have some effect). Of course foam has some resistance to airflow in both in and out directions so airflow plays a small part in its qualities while innersprings are not at all affected by air. Compression of an elastic material works in real time so it would initially feel much softer than a viscous material if you leaped on it but it only gives way in one direction (underneath you) so it will store energy underneath you (and push back) and may feel softer initially but firmer than a viscous material after a matter of some seconds. They have "bounce" in other words and this bounce is called resiliency.

Natural fibers are elastic and resilient to much lesser degrees but not viscous.They are very breathable so the air in them would flow away easily as they compress under pressure but the fibers are not nearly as elastic (stretchable) or resilient (bouncy) as non memory foam or springs and don’t "recover" as easily (horsehair is the most resilient of the commonly used fibers and recovers more strongly than wool which recovers more strongly than cotton). These are so breathable that there is very little resistance to air flow under compression (the air inside them moves away really easily) but since most fibers don’t have the resiliency to recover with as much force as springs or most foams and are less elastic, they will become more "permanently" compressed to differing degrees over time. They tend to need a resilient support layer underneath them.

Memory foam has a combination of viscosity and elasticitywhich is why its often called "visco-elastic" and is so different from other materials. It is made in such a way that its ability to recover over time (a period usually measured in seconds) is strong enough (even though it is slower) to "refill" the air but it is not strong enough to be resilient so it absorbs the energy of compression more than returns it with a "springy" feeling. It is less breathable and in the same way that it is more difficult to breathe in or out through a thick fabric, under compression the air both leaves and comes back against more resistance than most other foams. This is part of why it is slower than other materials to compress and return. Memory foam also softens in response to heat and humidity from your body or room temperature as it changes from from a more elastic material into a more viscous material and the length of time it is continuously compressed can also affect how much the memory foam softens as well. This change or "melting" also takes time when you lie on it and it also takes time to change back to elasticity and return to its shape when you get up. These two factors are the main reasons that lead to the slower compression and recovery (the memory quality) of memory foam. It also needs a good support layer underneath it.

Materials in a mattress that absorb compression forces and redistribute pressure away from pressure points are great for pressure relief but not usually as good for support.Layers that store energy and push back can also be very good at pressure relief in softer versions but are also better for support. This also depends to some degree on the point elasticity of the material and its ability to form a conforming cradle that mirrors the shape of the body. All viscous materials are good at this. Some elastic and more resilient materials are better at this than than others. The different layers in a mattress are usually designed in such a way that the complete mattress will have both supportive qualities and pressure relieving qualities. The core of the mattress which is the middle and bottom parts (usually innersprings, latex, or higher quality polyfoam) is the part that is primarily responsible for supporting the heavier parts of your body and keeping them from sinking in too far. The comfort layers which is the few inches (usually polyfoam, latex, memory foam, natural wool, horsehair, or synthetic fibres) are responsible for redistributing pressure so you don’t get "pressure points" when you sleep. They are also responsible for supporting the inner or more recessed parts of your body (like the small of your back, waist, upper thighs etc) so that gravity doesn’t pull them down against the natural position or curvature of your spine. These parts of your body don’t usually sink in enough for the deeper support layers to truly support them.

So what does all this mean in mattress terms?

Its unique combination of qualities leads to the advantages of memory foam for some .

Memory foam’s greatest advantage, because of its combination of properties, is generally considered to be its ability to distribute and relieve pressure.This does not mean however that it is dramatically better than the best of other materials as there are other types of foam like latex or high quality polyfoam that in their softer versions through compression alone are very close to memory foam in their ability to distribute pressure to levels below personal detection for most people. Even natural fibers that have broken in and formed a "cradle" to your body can distribute pressure very well and are often used in high quality mattresses. I should also mention here that there is one other material called "buckling gel" that in some cases may even be superior to memory foam or latex in terms of pressure relief but it is newer, not as common, and rather expensive. If a mattress relieves pressure below levels that you personally can detect, then which material is used in the comfort layers to do this is not so relevant except for other reasons such as its ability to support, its breathability, and its durability. In hospital applications (such as the relief of pressure sores) or with highly sensitive people, this slight difference in pressure relief can be more important however in most applications the difference is not as critical or even noticeable and the difference in materials used for pressure relief is more about how they feel and personal preference.

Another advantage of memory foam over a liquid or air is that memory foam requires body heat (in differing degrees with different formulations) to become viscous enough to "flow"so the "unmelted" areas of foam that are further away from your body will be firmer and resist pressure without "flowing away" from that pressure. This means that you are enclosed in a "stable cradle" of material that is "softer" close to you while it remains "firmer" further away from you. This combination of softness and firmness feels very good to people who like to sleep "in" a mattress that also feels "stable". Without this ability and the difference in viscosity and elasticity in different parts of the mattress, you would be sleeping "in" a viscous material which felt more like water or jelly without the feeling of "stable softness" that comes from a good memory foam layer. Other more elastic foams and natural materials to greater or lesser degrees are able to combine a feeling of softness with stability as well but memory foam is the leader here.

The qualities that provide this "stable cradle" effect is also connected to another of memory foam’s attractions to some which is its ability to isolate movementbetween people sleeping on a mattress. Its ability to absorb energy and isolate movement is better than most other materials because of its ability to both absorb energy and respond locally to movement. Latex in a comfort layer is also excellent here because of its ability to "localize" compression better than other materials but it doesn’t absorb energy nearly as much. Latex, certain high quality polyfoams, and certain innersprings (like pocket coils) in the support layers also contribute to a mattress’ ability to isolate movement and what is under your memory foam is important if this is a desirable part of a mattress’ qualities for you.

Memory foam, at least if it is a good quality and higher density memory foam (5 lbs density or above), is also more durable, will keep its qualities, and last longer than many other polyfoamsthat are typically used in a mattress, especially in the upper comfort layers. It is not unreasonable to expect the best quality memory foams to last 8 – 12 years (depending on its use and the "stresses" it is exposed to). This is not as long however as some very high quality polyfoams, latex foams, better quality innersprings, or natural fibers used in "upper end" mattresses, all of which can last longer without breaking down.

The same combination of qualities which are attractive to some can also be responsible for memory foam’s weaknesses for others .

Because of its low resilience, memory foam is a poor deep support material(the part of your mattress that supports the heavier parts of your body that want to sink in more). This is why it is so important to pay attention to the layers underneath the memory foam in a mattress as this is where the deep support (ability to keep your spine aligned) comes from. Treating memory foam as "supportive" as opposed to "pressure relieving" will usually lead to a potential purchaser paying less attention to underlying parts of the mattress and their resilience and other qualities, and possibly choosing a mattress with a poor ability to provide good alignment for a particular body weight distribution and/or different sleeping positions. Because memory foam can allow you to keep sinking in further over the course of the night as it softens, the underlying parts of the mattress that will prevent your heavier parts from sinking in so far that your spine is out of alignment is also important and some mattresses that have thicker layers of memory foam may keep you in good alignment when you first go to sleep at night but you may be out of alignment when you wake up in the morning.

Some side effects of memory foam’s greater sensitivity to heat can also lead to sleeping issues for some people.The deeper in a mattress someone sleeps, the more likely someone is to have issues with "sleeping hot". This of course is a quality of all foams where you "sink in" to some degree but it is compounded by the makeup of memory foams in general which allow a greater degree of sinking in and are typically less breathable (allow for less evaporation) than other foams. Even the newer generation memory foams which are more breathable (and usually a little "quicker") tend to be less so than other foams that are readily available. The greater breathability of other foams which have a more "open" cell structure (like latex or other polyfoams) tend to lessen the heat issues even for those who like to sleep more "in" a mattress using softer "non memory" foams. Natural fibers breathe best of all and tend to be cooler than any foam . especially memory foam.

This same sensitivity to heat can also lead in some cases to a mattress becoming "too soft" or "too hard" depending on the external temperaturein your bedroom, and can change its feel from season to season or from what you experienced in the store depending on environmental conditions. Different types of memory foam can be more or less sensitive to this but it can be more important to control the temperature of your bedroom with some memory foams than it is with others or with other materials.

Another potential issue of memory foams is that they take more time to adjust to different positions.This can be an issue for those who change positions often or are sensitive to the time it takes for the memory foam to conform to their new position as it can create short term "pressure" while it forms a new "cradle". Again different types of memory foams will take shorter or longer to conform to a new position. This "time to compress" or "rebound" that changes with temperature is both part of memory foam’s strength for some (creates a "stable cradle") and its weakness for others (doesn’t conform to new positions quickly enough or feels too firm). Some people may also be sensitive to a lack of resiliency or "pushback" which allows them to change positions more easily with a little "help" from the mattress and helps to support the lumbar area. This same lack of resiliency or "springiness" is also why it is often rated lower than other materials for the "other activities that take place on a mattress".

Finally there are the "offgassing issues" of some of the poorer quality foams that are common in the market today.While all memory foams and polyurethane foams in general (including the "green" ones) use some "nasty" materials in their manufacture, some of them have more of this material left in them by the time you sleep on them than others. For those that are sensitive to this offgassing, this can lead to issues ranging from a reaction to the unpleasant smell itself all the way to respiratory issues caused by the vapors. Your best protection against this is to make sure you know who manufactures the memory foam used in a mattress and not just accept the "re-branded name" that has been given to it (and to you). If the foam in your mattress has been certified by Certipur or Oeko-tex (or a similar organization), you can be reasonably sure that at least any smell or offgassing that you may notice has been tested for any potential harm it may cause you (within the limits of the test). More natural materials used in mattresses such as different fibers and good quality latex foam (which may also have a less unpleasant odor for a short time and is usually tested as well) are usually considered to be superior in this area. In the case of Certipur certification, the foam will also have been tested to some degree for durability and so is less likely to lose its beneficial qualities in a few months after purchase but the density of the memory foam would still be much more important durability factor than any limited durability testing done by CertiPur.

Without knowing what specifications and certifications the memory foam in your mattress has, I would not buy it. There are just too many retailers and manufacturers who are more than willing to provide you with this information which gives you the ability to make meaningful comparisons and make sure of the safety of your memory foam to waste any time with those who either can’t or won’t.

Some examples or different types of memory foams of different densities and different properties are in the videos here (with thanks to one of our manufacturing members Rocky Mountain Mattress).

While it’s not directly connected to the quality of memory foam itself because higher heat and humidity levels can speed up the softening and break down of any foam material . with more temperature sensitive materials like memory foam this can happen faster and so I would tend to avoid using memory foam with heated mattress pads or blankets or at the very least use them at the lowest setting and only for short periods of time. In some cases their use can also invalidate a warranty.

So there you have it. Hopefully I have covered the main points of the generic differences, strengths, and weaknesses of memory foam as a whole. In my experience and research, memory foam has been the subject of more misinformation and hype than almost any other material in a mattress and this confusion and misinformation has in my opinion led to too many poor or at least inappropriate mattress buying decisions. It is sometimes a frustrating process to "get to the bottom of things". Memory foam is certainly a valid choice in a mattress material for some people and there are many who love it however I believe that knowing more about what it does in comparison to other materials and why and how it does it, is an important part of buying a memory foam mattress. There are many choices of mattress construction available and the more those choices are based on fact, personal experience, and individual needs and personal preferences, the more likely you will be to buy a mattress that is perfect for YOU.

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.

Vacuum

Vacuum your memory mattress once a week to remove dirt and particles. Make sure you have used the upholstery attachment to regulate pressure.If the mattress has a zipper, you can open it and vacuum the internals also.Such cleaning is highly useful for assembled mattresses.

Spray

You can use antifungal and anti-infectious sprays to eliminate the harmful elements from your memory foam mattress. But you have to make sure they are free from moisture and dry off naturally.

Clean

Cleaning agents without moisture content such as vinegar can help in removing stains. You may also use the off the shelf products after reading the ingredient specifications.

Drying the memory foam mattress in the open air without exposing it to the direct sunlight is one of the simplest and safest methods after cleaning. It will also eliminate the pungent odor of the spray

How Long Do Memory Foam Mattresses Last – Summary

BMI VS Mattress Density

If your BMI is within the healthy range and you sleep alone, you may opt for amedium density mattress with three foam layers. If you are a couple with healthy BMI, you can opt for thesame type of mattress with high resistance for motion transfer.If your BMI is anywhere near the stage of obesity, it is better to opt for a high-density mattress.

Best Practices

Make sure you check the above-listed parameters in detail before placing an order. Then you can select the best mattress that supports your sleeping posture, Body Mass Index (BMI) and usage pattern. If you constantly change your posture during sleep, it is better to opt for Hybrid /composite mattress with four to five layers of foam. The top layer being Gel memory foam and the layer beneath that being PU foam.You can opt for a mattress company which gives you a free trial period of at least 15 nights.Then you can evaluate the mattress quality and durability.
