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 ft/ft/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.
