A wedge shaped, inflatable cushion is provided having its body portion divided into ribbed sections defined by transverse ribs. The cushion body portion is quilted transversely to form the ribs and ribbed sections, the sections thus being in communication with each other so that pressure due to weight of a heavy portion of the body on one section urges forward, with the rib as a pivot point, the head and other sections which support lighter portions of the body, to hold the head in a virtually upright position.
