ANATOMICALLY CONFORMABLE FOAM SUPPORT PAD Abstract of the Invention A convoluted foam pad for supporting a reclining human body on a bed including an area for supporting the shoulders of a body, an area for supporting the tail portion of a body and a general support area surrounding the shoulder and tail support areas for supporting the remainder of the body. In one embodiment the support area is formed by peaks arranged in rows, wherein each peak has a flat top and is spaced from any adjacent peak in the same row by a valley. The average valley thickness of the valleys in both the shoulder support area and the tail support area are less than the average valley thickness of the valleys in the general support area. In another embodiment, the shoulder and tail support areas are formed by parallel ribs separated and bounded by areas comprising flat-topped peaks and valleys. Another aspect of the invention is a method of manufacturing convoluted foam pads including compressing a foam block between two rollers having radially extended fingers of varying effective heights, cutting the compressed block into halves having varying peak heights and valleys having varying valley floor heights, and cutting the tops of the peaks off the create areas having lower volumes of foam than other areas.
