Abstract
A mattress is positioned on a flexible deck which is supported by tension members connected to a frame. In a preferred embodiment, the frame is formed of concave side rails, a horizontal head rail, and a horizontal foot rail. The upper surface of the deck is longitudinally concave and transversely convex. The mattress is tapered so that its upper surface is transversely and longitudinally crowned to counteract any potential sagging effect when a person lies on the mattress.
