Abstract
Abstract A cushion for the relief of, and the prevention of Decubitus Ulcers, has two elongated cylindrical portions spaced apart from each other over a substantial portion of their length, and supported in substantially the same plane by two similar cylindrical portions. The cylindrical portions are inflatable sealed cylinders which have interconnecting openings whereby inflation of all of the cylinders is accomplished through a single valve in communication with one of the cylinders. The cylinders may be inflated by any of a number of fluid media including air and other similar gaseous materials; foam, mud, or any other similar liquid materials.
