What's a Mattress Made Of?

Common Mattress Materials

The most common mattress materials are foam, wool, cotton, polyester battling, steel coils, flame retardants, and adhesives. Foams such as memory, polyurethane, or gel memory foam relieve pressure points and help regulate temperature. Similarly, wool is used for temperature regulation and extra padding. Cotton is a breathable material used in both the inside and outside of mattresses. Pillowtops and mattress covers are made of polyester battling. Adhesives bond mattress layers. Steel coils, either open coils or individually wrapped, offer firm support. Finally, laws require fire-resistant materials be used in the construction of United States-sold mattresses. Any and all of these materials can be used in conjunction with each other depending on the qualities the manufacturer wants the mattress to have.
