A foam support pad for nonambulatory persons provides for a wide weight distribution and maximum aeration of skin areas in contact with the pad to prevent the formation of decubitus ulcers. The top surface of the pad has an array of protuberances and valleys thereon, with air channels extend through the pad. Air channel cores are located beneath the protuberances, with some of the air channel cores extending close till the top of the protuberances, and other of the air channel cores extending through the top portions of the protuberances.
