Abstract
A mattress constructed with multiple foam layers joined together provides reclining support with pressure redistribution for heavy weight persons, particularly those weighing over 350 pounds. The mattress includes: a core layer having a substantially planar top surface and at least two spaced apart regions in a bottom surface from which foam material has been extracted to leave cavities separated by an interconnected network of foam walls, a top layer of viscoelastic foam with an air permeability above 60 ft3/ft2/min, and a bottom layer of stiffer supporting foam. The open cavities of the core layer are directed away from the body supporting top surface of the mattress and contain one or more gels.
