ABSTRACT:
A relatively shallow mattress for a bed which has three integral parts: an inner bladder, an outer bladder and a mattress cover. The inner bladder is formed from a rectangular top and bottom side welded together along the edges. The top side contains a valve. The outer bladder is effectively a safety cover for the inner bladder. It surrounds the inner bladder and but for a circular opening which allows access to the valve on the top side of the inner bladder, it is fluid tight. It is made in a similar fashion to the inner bladder which it permanently encloses. The mattress cover has an upper surface made of a quilted ticking. This ticking incorporates a thermal barrier layer. The mattress cover has a bottom and sides made from a relatively light woven cloth fabric. The mattress cover totally surrounds the bladder. An elongate zipper along the edge of the top surface allows insertion of the bladders and access to the valve used for filling.
