Abstract
A water mattress construction includes an outer water inflatable polyvinyl chloride ('PVC') shell having a top and a bottom surface with side walls connecting the top and bottom surfaces and forming corners where any two side walls meet. The mattress is improved by attaching one or more patches of webbing made of a laminated spun bound polyester encased in PVC to the mattress shell. The webbing having intermittent raised areas and intermittent openings is preferably attached to the four corners of the mattress to provide a frictional gripping adhesion between the bed clothing and the mattress to prevent sliding movement of the bed clothing on the mattress.
