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. It is also preferred that the first section be disposed so as to support the lumbar section of a human user reclining thereon. The lumbar support section preferably extends somewhat higher above the mattress than the other two sections. In one embodiment, a variable density pad is disposed below the backing layer, with a more dense section of the pad disposed below the lumbar section of the top.
