Kinds of mattresses are classified by their major component materials, for comfort and for support – innersprings, memory foam, latex, water, air, wool, cotton, feathers/down. Various natural and synthetic fibers make up mattress covers, and there are special materials used in fire barriers.
This site naturally focuses on memory foam, but other materials do play roles, especially when we are comparing different brands and models of mattresses. In many cases two or more materials share responsibility for the performance of a particular model. For example, several models by several manufacturers combine latex and memory foam. Some of these latex-memory foam hybrids, such as the Casper Mattress, have the latex on top. For others, such as the Fibro-Pedic, the top layer is the memory foam.
