Pillowtop mattresses are often mistakenly thought to be some of the softest mattresses when, in fact, the term "pillowtop" refers to the design of the mattress rather than its comfort. A pillowtop mattress simply has an additional layer of padding on top of the mattress to fine tune its comfort. This layer can be put on an extremely firm mattress to take the edge off while retaining a dense and supportive feel, used to improve the initial comfort of a mid-range mattress, or added to an already soft mattress to become very soft. Pillowtop mattresses are perfect for couples where one sleeper needs rigid back support, but the other sleeper dislikes a firm feel. And as with any mattress from Sealy, you are getting the quality and comfort of America's second leading mattress brand, so you can rest assured that you are making a good investment on an excellent product.
