ABSTRACT:
A bed mattress support apparatus and method includes a fluid filled bladder or multiplicity of bladders to vertically support a rigid platform. The rigid platform provides a suspended surface to support a mattress, foam pad, or other mattress-like device. A frame surrounds the bladder to prevent lateral movement of the bladder. Motion limiting features control vertical displacement of the platform.
