Abstract: A back support provides a generally vertical and rigid panel removably installable along one edge of a bed, against which a person may brace his or her back or other body part as desired while reclining on the bed. The present support comprises a frame with two opposed legs extending therefrom, with the legs each having a ninety degree bend therein. The legs may thus be inserted horizontally between the mattress and box spring or frame of a bed, with the frame being held generally vertically at the edge of the bed. The legs also telescope within the ends of the frame for height adjustment, and pivot to lie coplanar with the frame for carriage and storage of the device. The frame includes a rigid panel thereacross, with the panel having a cushion removably secured thereto and facing the center of the bed when the support is installed on the bed. The cushion includes a series of pockets on the outer surface thereof, for the removable insertion of therapeutic articles (e.g., hot and cold packs, etc.) therein.
