Abstract
A multi-zone support generally includes a top foam layer, a middle foam layer located beneath the top foam layer, and a bottom foam layer located beneath the middle foam layer. The resistance to a compressing force generally increases per layer from top to bottom. The top layer has a top and bottom planar surface. The middle layer incorporates five zones of support. Three of the zones include a sinusoidal surface for supporting the head/shoulder, hips, and legs/feet while the other two zones include a sold surface for supporting the back and thighs. The bottom surface includes a number of channels, the channels help to carry heat and moisture away from the support.
