A 'mattress' is a mat or pad, usually placed on top of a bed, to sleep or lie upon. A mattress is usually placed on top of a bed base that may be solid, as in the case of a platform bed, or elastic. Flexible bed bases can prolong the life of the mattress. Modern mattresses usually contain either an inner spring core or materials such as latex, viscoelastic, or other polyurethane-type foams. Mattresses may also be filled with air or water, or a variety of natural fibers, such as futons.
