Sleeping comfort depends on the top layers of your mattress...
If you have had a pillowtop mattress that began losing support, creating body impressions, after just a couple of years, you already know that the durability of the foam layers is the single most important consideration in the useful life of a new mattress.
There are plenty of different materials used to construct modern mattresses, however, virtually every mattress depends on various types of foam to create more comfortable conforming layers above the supportive core of the mattress. While the durability of support layers is important, what you generally feel when testing a new mattress are the top layers of foam, which are considered to be the comfort layers.
There are tremendous variations in the durability of foam...
Manufacturers choose from a wide variety of foams when constructing the comfort layers of the mattress they design, including low, medium and high density polyurethane foams, 3lb to 5lb memory foam, and latex foam, which can be manufactured latex, blended latex and 100% natural latex.
As you you might expect, rarely do mattress manufacturers use top quality foams in their mass produced mattresses, they create more affordable mattresses by using less expensive foams, which simply do not have the durability of top quality foams.
Latex is the most durable of all foams, when the latex is manufactured by industry leaders, including Talalay Global, Latex Green and Latexco. We find that many consumers, looking for a natural mattress material, prefer the 100% natural Talalay from Talalay Global and 100% natural Dunlop from Latex Green, both extremely durable mattress materials.
Most of the Talalay latex from Talalay Global, and the Dunlop latex from Latexco are high quality blended latex, using both the natural latex and synthetic latex to create a more affordable latex material. Blended latex from these manufacturers is generally just as durable as 100% natural latex.
However, most of the latex used in mattresses from major manufacturers is what is called manufactured latex, which means it is only synthetic latex, and, along with imported latex from unknown manufacturers, does not have the durability that higher quality latex provides.
While not as durable as latex, high quality memory foam is is often among the most durable polyurethane foams, but only in the 5lb versions from a major manufacturer such as Foamex here in the US. Many people have experience with budget memory foam mattresses from some of the major retailers, which are usually disappointing from a durability standpoint.
These mattresses generally use memory foam that is at best 3lb memory foam, often imported from unknown manufacturers, which is simply not very durable. It's not unusual to find similar memory foam in many pillow top or hybrid mattresses, so the quality of the memory foam will determine the useful life of that mattress.
The most commonly used foam in mattresses is polyurethane foam, which can be found in the comfort layers, pillow tops and euro tops of many mass produced mattresses. These layers of polyurethane are designed to create a comfortable layer between you and the mattress springs.
Many consumers are not aware that polyurethane foam is available in low, medium and high density foam. This density has nothing to do with the firmness of the foam, rather, it relates directly to the durability of the foam, regardless of the firmness used.
When the foam comfort layers of your mattress are constructed of low or medium density foams, the mattress will break down much sooner. While the combination of these layers can offer comfort in the showroom, a chain is only as strong as its weakest link, and once one of the foam layers begin to break down, you begin to have body impressions.
A new trend with mattress manufacturers is to combine different types of foam for the comfort layers, which can include polyurethane foam, memory foam and latex foam. Many mass produced mattresses, including top end brands, often use low or medium density polyurethane foam, 3lb or 4lb memory foam, or manufactured synthetic latex in these combination comfort layers. It is the durability of these foams that determines the useful life of your mattress.
A Natural Latex Mattress Offers Unsurpassed Durability
Both durable and comfortable, natural latex is the finest mattress foam...
The long term comfort of your mattress depends completely on the durability of the materials used to construct the mattress. Natural latex foam reigns supreme as the most durable of all foams, and, when used in support layers, it is much more durable than inner springs.
The most obvious characteristic of natural latex is its comfort, which is lightly buoyant, comfortably conforming, cooler than other foams and offers excellent support.
The primary reason for the comfort and support of latex is that it offers the choice of different firmness levels, which allow many latex mattresses to have the firmness levels individually designed, based on your size, weight and sleeping position. The biggest selling point is that once you have your perfect firmness combination, you can expect very little change in comfort and support for many years to come.
If latex was simply much more durable than other foams, it would be its strongest selling point, however it raises the bar even higher by offering unsurpassed comfort. Get off the mattress merry-go-round, and start sleeping on a natural latex mattress.
