ABSTRACT:
A mattress having a top surface component and a spring component. The top surface component comprises multiple layers. The first layer is the cover material for enveloping the entire mattress. The second layer is a fiber material covering the entire top surface of the mattress. The third layer is convoluted foam subtending the fiber layer and having a plurality of peaks for supporting the fiber layer in a no load condition. The fourth layer is a backing material for the convoluted foam layer. The peaks of the convoluted foam layer compress either completely or partially when a weight is applied and return to their original no load position when the weight is removed. The compression and return action of the peaks of the convoluted foam layer exercise the fiber layer preventing the matting thereof and cause the movement of air to keep the fiber layer dry.
