An open cell foam pad is ripple-cut to create a convoluted face of hills and valleys. A plurality of air-flow channels are cut through the pad in each valley formed. The channels with plugs therein provide the user of the pad with the ability to direct air circulation through the pad to certain parts of the body. These air channels also function to dissipate excess body fluids or medicines. For situations demanding the highest possible amount of air circulation, the ripple-cut pad with open air-flow channels is flat-topped. The size of the flat area on each hill is determined by the weight of body to be supported. For a body weight under 100 pounds, a maximum area of 1/2 inch by 1/2 inch is used with a contact surface to open space ratio of 1:3. For a body weight between 100 and 150 pounds, a maximum area of 1 inch by 1 inch is used with a contact surface to open space ratio of 1:1. For a body weight greater than 150 pounds, a maximum of area of 11/4 inch by 11/4 inch is used.read more
