To prove the point, we are going to use the warranty of two prominent mattress manufacturers, Dormia and Tempur-Pedic. In case you dont know both Dormia memory foam and Tempur-Pedic mattresses are made of 100% polyurethane foam. Polyurethane foam is made from petroleum so it is essentially plastic foam. The Tempur-Pedic warranty states: It is understood that this limited warranty does not include a normal increase in softness of the Tempur pressure-relieving material. So Tempur-Pedic admits that their all-polyurethane foam mattresses soften and, by-the-way, it isnt covered under the warranty. Dormia is no different. Their warranty states: It is understood that this does not include a normal increase of softness in the foam. So both manufacturers of all polyurethane foam mattresses admit that poly softens.
There are basically three types of Sealy TrueFoam mattress to choose from; the 8 series, 9 series and 11 series - the number is the thickness of the mattress in inches. The 8 series comes with 5" of high-density foam in the core and 3" of memory foam in the top layer. The 9 series comes with 6" of high-density foam in the core and 3" of top layer. What exactly are the benefits of the 9 series over the 8 series I can't really say as both have a 3.5" top layer of memory foam - I don't see how an extra one inch of high-density foam in the core makes the 9 series any better than the 8 series. The 11 series comes with 6" of high-density foam in the core, a 3.5" visco middle layer and 1.5" convoluted visco top layer.
This is the part that provides comfort. Padding is usually made of polyurethane foam, puffed-up polyester, or cotton batting. Some mattresses have a foam layer just below the quilted top layer. Softer foams feel almost moist to the touch, and firmer foams do not spring back as quickly. Below this layer, there is a layer of cotton batting that caused the mattress to feel firmer in areas such as the middle of the mattress. Finally, there is an insulation layer that lies on top of the coil springs so that they cannot be felt from the top of the mattress. It also protects the coils from damaging the top layers.
Kingsdown do manufacture top rated mattresses and many reviews of Kingsdown mattresses are highly favorable. Before buying a quality mattress you should decide what type best suits your needs. If you prefer traditional, inner-spring mattresses then a Kingsdown is probably as good as Sealy, Serta and Simmons mattress of the same type.A Review Of Restonic ComfortCare Mattress
