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.
FireBlocker is an open-flame resistant system used in every Serta mattress. Again, Serta was the first national mattress brand to offer a flame-retardant system to its customers.
Some other types of mattresses are made of latex foam or memory foam. These can be purchased in different densitiesthe higher the density, the more firm it is.
