<p>A multi-zone support generally includes a top foam layer (12), a middle foam layer (14) located beneath the top foam layer (12), and a bottom foam layer (16) located beneath the middle foam layer (14). 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 (14) incorporates five zones (31, 33, 35, 32, 34) of support. Three of the zones include a sinusoidal surface (36) for supporting the head/shoulder, hips, and legs/feet while the other two zones include a solid surface for supporting the back and thighs. The bottom surface includes a number of channels (50), the channels (50) help to carry heat and moisture away from the support.</p> |
