Sofa sleeper with integral air mattress and valve

摘要

This invention is directed to a mattress assembly for use in a sofa sleeper. The mattress assembly has a first mattress that has an inner-spring construction. Disposed above the first mattress is a second mattress that has an air bladder construction. The second mattress further includes a cover border coupled to an edge of the first mattress and extending upwardly therefrom; and a top cover removably coupled to the cover border, the top cover and cover border forming a cavity for receipt of the air bladder. The air bladder of the second mattress has a valve, which is located adjacent the head end of the mattress. The valve is adapted to selectively allow air into and out of the air bladder. The mattress assembly thus provides the combination of an innerspring mattress with an air mattress. The location of the valve allows the air mattress portion to be deflated properly and allows convenient access to the valve for inflation or air pressure adjustment purposes.
