Each cell member includes an opening into their respective hollow interiors for permitting inflation and deflation of the cell member. Each cell member also includes interlocking ribs on the perimeter of the opening into the cell member hollow interior to provide a sealing means for permitting the formation of a substantially air tight closure each opening.
