Abstract
A flexible cover for a waterbed mattress is constructed as a three-ply construction. A central ply formed of heat insulating materials is sandwiched between two similarly constructed outer plies that are formed of moisture-absorbent materials. Moisture generated by the person's body is trapped within the uppermost layer, or ply, of the cover. Body heat passes through the moisture-absorbent layer into the central ply of the cover, where it is trapped, or contained. The person, therefore, does not experience the chilling effect that persons sometimes feel when lying on a waterbed. The three-ply cover is reversible, such that the cover can be placed on the waterbed mattress with either major surface facing upward.
Claims5
A three-ply cover for a conventional waterbed bladder, comprising:
- a central ply, having thermal insulation properties;
- said central ply, having a first major face and a second major face;
- two outer plies secured to said major faces of said central ply;
- one of said outer plies being bonded to said first major face, the other outer ply being bonded to said second major face;
- said central ply, comprising, an inner sheet of thermally reflective material having oppositely facing surfaces, and a flexible foam panel, bonded to each one of said surfaces;
- each foam panel having the same thickness;
- each outer ply comprising a quilted pad that includes two woven cloth sheets and an intervening non-woven fibrous batting layer;
- said cloth sheets being sewn to each other and to said intervening layer of batting with a criss-cross pattern of stitches;
- each outer ply being formed separately;
- each outer ply being adhesively bonded to said central ply;
- and
- each outer ply having the same construction, whereby the three-ply cover can have either surface thereof engaged with the waterbed bladder.
