Abstract: A bed and mattress structure includes an articulating frame having longitudinally spaced head, seat, thigh, and foot sections. The head, thigh and foot sections are movable relative to each other and relative to the seat section. A deck on the frame supports a user. A mattress is interposed between the deck and the user. The mattress includes a plurality of longitudinally spaced apart, transversely extending air bladders corresponding respectively to the frame sections. A power driver tilts the frame sections to desired tilted positions. An air supply fills each bladder to desired air pressures to support the user. A drive controller controls the power drive for tilting the frame sections to various desired positions. An air supply controller controls the air supply for filling the air bladders to desired air pressures. A hand held controller includes a key pad cooperating with a programmable device to provide signals through a cord in response to inputs from the user.

Abstract: A variable firmness mattress structure includes a plurality of longitudinally spaced apart, transversely extending air bladders and an air supply for filling each bladder to a respective desired air pressure to support a user at a desired mattress firmness. A control system for the variable firmness mattress structure includes at air controller cooperating with the air supply for filling the air bladders to desired air pressures and a hand-held controller in communication with the air controller. The hand-held controller is configured to receive a first input from the user indicating that a first desired mattress firmness currently exists and to transmit to the air controller a first signal corresponding to the first input. The first desired mattress firmness corresponds to a first set of respective desired air pressures in the bladders.

Abstract: According to the present invention, a plurality of mattress structure components are arranged for selective assembly to provide a customized mattress structure at the point of sale to accommodate the musculoskeletal condition and interface pressure preference of the user. The mattress structure components include a perimetrical frame having a central opening and a plurality of cores which are provided in a variety of firmness and support characteristics such that various combinations of firmness and support can be selectively provided. The frame is preferably made from a relatively firm foam rubber such as a high resiliency, high density urethane foam and the plurality of cores includes air bladders, "zone foam" elements, "sculptured foam" shaped from foam blocks, and combinations thereof for filling the central opening of the perimetral frame. The mattress is also suitable for use with an articulating deck having longitudinally spaced head, seat, thighs and foot sections.
