ABSTRACT:
A multiple position air mattress system for achieving various support positions includes a first mattress, a second mattress, and a bellows unit attached to the second mattress. The bellows unit is extendable for either elevating the second mattress or providing a support for an individual. The multiple position air mattress system can assume a prone bed position with the mattresses longitudinally adjacent each other and the bellows unit deflated and an inclined bed position with the mattresses longitudinally adjacent each other and the bellows unit inflated under the second mattress. In the inclined bed position, the degree of elevation of the second mattress can be finely adjusted by increasing or decreasing the inflation level of the bellows unit. A fourth inflatable member may be positioned on the top side of the second mattress to support the lumbar section of the user's body. A fifth inflatable member may be positioned under the user's leg to provide adjustable elevation of the legs. A sixth inflatable member may be positioned on the top side of the second mattress to support the user's neck. A pump unit including a plurality of ports and a corresponding plurality of hoses are coupled to inflatable members to provide for independent inflation thereof. A control unit is operably coupled to the pump unit to provide for independent control of the inflation levels of the members. Preferably, a cover substantially encloses the tops, bottoms and sides of the members. Foam inserts may surround at least three sides of the perimeter of the first and/or second mattresses.
