Abstract
A system for elevating the head portion of a bed assembly defined by a mattress and a box spring foundation, including a double pivot hinge secured to the border wires on either side of the mattress, a double linkage hinge secured to the upper border wire assemblies connecting the foundation to the mattress for maintaining the mattress in its position of alignment on the foundation, and an elevating mechanism for jointly raising and lowering the corresponding head portions of the mattress and foundation.
Claims21
