ABSTRACT:
A waterbed mattress is provided with a plurality of separate, free-standing cells, arranged in a "honeycomb" pattern. The cells are preferably hexagonal in plan. Each cell is provided with its own fill valve and is removably encased in its own protective waterproof pouch. The cells are held together by a cover member such as fitted sheet or a conventional zippered mattress cover. In the preferred embodiment of the invention, the cells are arranged in rows and columns on an insulating substrate having upstanding end portions alignable with the head and foot of a bed frame. Each upstanding end has a plurality of cut-out portions defining a jagged inner edge for receiving the corners of the hexagonal cells. The mattress assembly may also be provided with a heating unit comprising a plurality of heating pads electrically connected in parallel with one another and having a temperature control unit.
