Abstract
A foam mattress in which a layer of latex or latex-like foam placed above a layer of memory foam is described. This construction of the mattress provides the contouring pressure relief that a visco-elastic foam provides with a top surface with quick recovery (a latex-like “bounce”) that prevents people from getting “stuck” in the visco-elastic foam and improves the springiness of the mattress. The mattress may also include straps and cinches to aid in transportation of the mattress. The mattress may also include removable covers that aid in keeping the mattress clean.
