ABSTRACT:
A self-contained compressible chamber for supporting the perimeter of the fluid-filled, flexible bladder of a waterbed mattress which provides improved structural rigidity. The chamber includes a compressible medium and an elongate, substantially rigid member extending therethrough. Individual chambers are retained in supporting engagement with the perimeter of the bladder. The ends of the rigid members of the individual chambers are fastened to adjacent rigid members, whereby the perimeter of the bladder is substantially completely supported with an improved degree of structural rigidity while retaining mattress edge comfort.
