Abstract: A cover for a waterbed mattress includes a top layer suitably sized to cover the waterbed mattress and an inner backing layer of substantially the same overall outline as the top portion disposed so that the top layer lies over the backing layer. A bottom is spaced away from the top layer and the inner backing layer so as to provide a cavity for a water mattress, with the bottom disposed below the cavity and the inner backing layer being disposed above the cavity. The top layer is divided into at least three sections, each section extending substantially across the top layer. The first section is fixedly secured to the inner backing layer by stitches disposed in a first stitching pattern while the other two sections are fixedly secured to the inner backing layer by stitches disposed in a second stitching pattern. It is preferred that one of the stitching patterns be a continuous wave stitching pattern and that the other be a tack and jump stitching pattern.

Abstract: A water mattress has an outer shell and a wave dampening fiber baffle positioned within the shell. The baffle includes an upper comfort layer formed of a porous mass of bound-together fibers and a lower support layer formed of a porous mass of bound-together fibers. The fiber layers are separated by a wave barrier which is generally coextensive with both the upper and lower layers. The denier characteristic of the fibers in the upper comfort layer is no greater than half the denier characteristic of the fibers in the lower support layer.

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.

Abstract: A waterbed mattress has a baffle structure formed of a buoyant pad capable of floating freely within the mattress and a plurality of chambers attached to the pad. An upper portion of the chambers depend from the pad and are attached to the undersurface thereof. A lower portion of the chambers are attached to and depend from the upper chambers. There are openings conecting the upper and lower chambers for the passage of water therebetween when the weight of a person is placed upon the mattress. The pad and chambers have sufficient buoyancy that the baffle structure floats within the waterbed mattress.

Abstract: A waterbed mattress comprises an inflatable container formed of a flexible plastic material with a generally planar top sleeping surface and a generally planar bottom. There are generally vertical side walls and a generally vertical head end wall and a generally vertical foot end wall. the head end wall has a greater vertical height than that of the foot end wall whereby the top sleeping surface slants from the head end to the foot end.
