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.
