Abstract: The present invention is a mattress which consists of a series of elongated foam members positioned adjacent each other in parallel, a plurality of foam blocks separating each elongated foam member, a series of parallel slots formed along one surface of each elongated foam member, and a series of elongated slats mounted perpendicularly to the foam members. The slats are dimensioned and configured to fit within the slots of adjacent foam members such that the slats lie flush with respect to the surface of each foam member. The slats are held in place on each foam member by elongated webs which are bonded to the surface of each foam member. Each web extends between the opposite ends of the foam member and is dimensioned to cover over the slats where the slats overlap the foam member. The mattress construction also includes a mattress cover which encloses the foam members and slats.
