ABSTRACT:
There is disclosed a cushion of flexible plastic sheet material adapted to be filled with water or other liquid wherein the interior space is divided into at least two compartments, one of which is annular, the shape being particularly adapted to provide a cushion with firm, comfortable support while at the same time being simple and inexpensive to manufacture. Separate filler openings are provided for the two compartments which permits their being filled independently, to different degrees if desired. The cushion is preferably provided with a textile fabric cover which is removable for storage and shipping.
