Memory Foam Mattress Buying Guide

The first question that needs to be answered is: What exactly is a memory foam mattress?  These mattress are an engineered, cutting edge type of visco-elastic PU foam.  Real memory foam mattresses are made out of visco-elastic with many millions of sphere-shaped open cells.  These cells have a special design that makes them very responsive to temperature as well as body pressure points.  A mattress made out of visco-elastic therefore has the ability to contour itself so that it matches your body’s shape and provides you with the most support where needed. In addition to the support it provides, another way that a memory mattress is different than a standard mattress is that its foam has an open cell design that lets air freely pass through the material.  This helps to keep the mattress, along with the user, cool and excessive sweating is prevented as well.

But before we continue with the guide, let us examine the best memory foam mattresses we have today.

Continuation of the guide……

Memory mattress made out of visco-elastic materials have been quite popular across Europe for a very long time.  Hospitals, institutes and health authorities have used them due to the fact that a patient’s body is supported more effectively by them and therefore prevents the development of pressure points, which can frequently happen any time a patient has to spend long amounts of time in bed.

The consumer market has only increased in recent years for visco-elastic foam markets as customers have noticed the many benefits that the mattresses offer compared to standard spring based ones.  As consumer demand has increased for this kind of mattress, the different kinds of foam mattresses have increased as well.  The main problem here is that quality can widely vary, meaning that customers need t consider a number of critical factors before being able to make the best decision in terms of which mattress with meet their needs the best.

Things To Look For When Buying A Memory Foam Mattress

Whenever you are considering buying a high quality memory foam mattress, you need to take into account several important considerations and factors.  The three most critical measurements and ratings that you should consider when trying to understand what the specifications are of a memory mattress are its Density, ILD Rating and Firmness Rating.  Those are the three criteria that will be the determining factors in how well the mattress performs its job and your experience with it.

So lets look more closely at the major factors.

Mattress Size

You might not be aware of of this, however most individuals spend about one third of their lives lying in bed.  There has been some very interesting research done that shows that a high percentage of individuals spend more money on their couches than they do mattresses and beds.  In Europe it is a different situation, where the mattress is considered to the most important purchase that an individual can make.  That makes sense considering how much time we spend on our mattresses and beds.  Whatever we decide to purchase needs to be just right.  Of course we all want to have a comfortable, restful night’s sleep since it feel so good and has a direct connection to having a healthy body and mind.

When all of the above it taken into account, it’s very important to buy as large a mattress as you can in terms of your budget, bed and bedroom.

How Suitable Your Bed Is To Use With A Memory Foam Mattress

A majority of mattresses may be used with most bases and bedsteads.  However, some will help with making it feel more comfortable and perform better than others.  For example, if you have a bed or bedstead that has a slatted wooden base, it is recommend that you place the slats no further apart than 2 to 3 inches.  Most of today’s foam mattresses are suited for using with a divan sprung or box spring kind of bed as well.  You just need to remember that the mattress doesn’t need the base to provide any extra support.  What that means is that the best foundation to use with the mattress is a solid and stable platform.

Why It Can Be Confusing Comparing Different Mattresses By Manufacturer And Model

In general it is thought to be in the best interest of the retail to make it as difficult as they can for customers to be able to effectively compare various memory foam mattresses in terms of their actual specifications and value for the money.  One way of making a reasonable comparison is comparing Tempur’s products with another brand’s product, since Tempur was the first company to introduce foam mattress and is the market sector’s leader to this day.

Why Mattress Depth Is Important?

The depth of a mattress is important.  However, when it comes to depth with memory foam mattresses the most critical aspect is the depth of the actual foam layer since that will be what determines how well it allows you to sleep comfortably, supports your body and relieves pressure points.

Understanding Memory Foam Density

The density rating for a foam mattress is in reference to the visco-elastic memory’s top layer density instead of the entire mattress.  For any mattress the supporting base is the really memory foam uses high resilience or impact resistant polyurethane foam.  This should never be mistaken for what is referred to as visco-elastic memory foam. For any foam mattress, the most expensive and important part is the top layer of visco-elastic foam. It is the most critical component.

What that means is that the density rating corresponds to the amount of visco-elastic memory foam that is contained within the foam portion of the mattress.  So the lower that the density rating is, the less raw material has been using in making the layer of memory foam, meaning that the cells or air cavities are a lot larger.  A higher density means that the memory foam is heavier and there will be more cells or air cavities and they will be packed tighter together and be a lot smaller as well.  That means wearing them down is more difficult and it will help to determine how long the mattress lasts in addition to the muscular and skeletal support that it provides.  Experts have recommended and said that memory mattresses with higher visco-elastic density ratings provide more support compared to mattresses that have lower density ratings.

A high density rated, high quality mattress will feel very full bodied and sumptuous, whereas a lower density rated, lower quality mattress will not even come close to comparing.  However, it is worth noting that doesn’t indicate how firm a memory bed is.  Leading memory foam mattress manufacturers often change how firm the mattresses are on matter what the density level is.  That is very important to remember when buying foam since lower density products are produced by many manufacturers.  For instance 50kg/m3, which makes memory foam feel to customers like it is firmer and makes them think that the mattress has a higher density rating than it actually does.  Inevitably, the cell structure on mattresses that have lower density rating will wear down faster and easier and result in the memory bed losing its shape very fast.

One good rule of thumb to follow is to search for companies offering a long and comprehensive guarantee or warranty, since many makers of foam mattresses with lower density don’t offer over 12 months with their warranties or guarantees.

The density rating on a mattress is calculated by the memory foam’s weight in cubic meters.  That is why it is expressed as a weight,for instance 85kg/m3.  If you prefer imperial measures and aren’t too familiar with the modern measurement system, it is the same calculation basically.  A cube of 1 foot modern memory foam is weighed.  The density displayed imperially is in pounds, for instance 5.3 lbs.

How To Understand The Way Memory Foam Will Really Feel

Usually the best way of understanding how memory foam is going to feel is by taking a low at the manufacturer rating.  A majority of them use terms like firm, medium and soft.

The main problem with that is mattress manufacturers are not required to followed a specific test or guide of firmness so that you can compare all mattresses with one another.  That is a problem when you are attempting to understand what the differences are between various memory foam products in terms of how soft or firm the foam feels since it will vary between individuals.  When it comes to comfort we all have various preferences. Taht is why it’s important to not just rely on the manufacturer’s firmness rating, but also look into the ILD for understanding how hard or soft a mattress feels.

Understanding What A Memory Mattress ILD Rating IS And Why It Is Important

When the density and ILD of a foam mattress are both taken into account that is what will provide you with the most accurate picture of quality and firmness of the mattress.

ILD is short for Indentation Load Deflection.  Simply put, it tells you how firm or soft a memory foam mattress is.

The ILD of a mattress is calculated by manufacturers by measuring how much pressure in pounds is needed for indenting 25% into a 4 inch layer of memory foam.  It is testing through using equal amounts of pressure over 50 square inches for pressing 25% into the memory foam.  The pressure level needed for indenting 25% into the foam’s total depth gets is calculated and expressed in terms of its weight.

The following example can help you better understand the ILD rating of a memory foam mattress.

8 pounds of pressure is needed for indenting the softest memory foam 25%, whereas 20 pounds of pressure is needed for indenting into memory foam that is extremely firm.

The ILD rating for most memory foam mattresses is displayed in terms of a range.  For example 10 to 12, instead of only one number. That is because the ILD rating can have slight variations to it depending on where the foam has been stored prior to testing it or how it was conditioned. Moisture and humidity are two factors contributing to this slight variation.  For example a memory foam mattress that has a 13-15 ILD rating means it is a medium to firm mattress that is 13 to 15 pounds.
