Abstract
A cushion for reducing the incidence of decubitus ulcers in immobilized patients has upper and lower sheets peripherally seamed together to form an enclosure which contains a quantity of small plastic spheres or beads. A baffle system is arranged within the enclosure for maintaining the beads in an even distribution throughout the enclosure. The material of the baffle system and upper sheet is permeable to air flow, while the lower surface is not, whereby air may be forced to flow through the enclosure and out the upper sheet from a blower interconnected to an end of the enclosure by a duct.
