An insulated mattress pad eliminates the necessity of heating the water of a waterbed by electrical or other means. The mattress pad includes a pocketed covering of washable materials into which is removably inserted an insulating pad formed of an insulating laminate. The laminate comprises at least one layer of insulating air bubbles sandwiched between heat reflecting skins and abrasion resistant outer sheets. The mechanical stiffness of the mattress pad allows the use of thinner backing pads, such as foam, while maintaining the comfortable feel of thick backing pads.

1. A laminated insulating pad comprising: a. at least two layers of encapsulated air bubbles, each layer of air bubbles comprising a discrete sheet of clear polyethylene material embossed on one side with a plurality of indentations terminating in crowns, and a skin of heat reflective material substantially coextensive with and bonded to each embossed sheet on the open sides of the indentations to encapsulate the air in the indentations, the crowns of the layers of embossed sheets being bonded together in superimposed and coterminus relationship to thereby create a pair of oppositely facing outer surfaces formed by the skins; and b. a pair of abrasion resistant outer sheets of clear polyethylene material substantially coextensive with the layers of encapsulted ir bubbles, one outer sheet being bonded to each outer surface of the bonded layers of encapsulted air bubbles to prevent abrading of the encapsulated air bubbles during continuous flexing use. 2. The laminated insulating pad of claim 1 wherein the reflective material is a metal foil. 3. An insulated mattress pad comprising: a. a pocketed covering having substantially coextensive rectangular shaped top and bottom covers fastened together along three edges thereof to form a pocket, the top cover comprising an outer layer moisture resistant air permeable non-woven fabric and an inner layer of fiberous moisture absorbing material attached to the outer layer, the bottom cover being of a moisture resistant air permeable non-woven fabric; and b. a laminated insulating pad removably inserted in the pocket of the covering, the insulating pad comprising: i. at least two layers of encapsulated air bubbles, each layer of air bubbles comprising a discrete sheet of clear polyethylene material embossed on one side with a plurality of indentations terminating in crowns and a skin of heat reflective material embossed substantially coextensive with and bonded to each embossed sheet on the open sides of the indentations to encapsulate the air within the indentations, the crowns of the layers of embossed material being bonded together in superimposed and coterminus relationship to thereby create a pair of oppositely facing outer surfaces formed by the skins; and ii. a pair of abrasion resistant outer sheets of clear polyethylene material substantially coextensive with the layers of encapsulated air bubbles, one outer sheet being bonded to each skin of the bonded layers of encapsulated air bubbles to prevent abrasion of the encapsulated air bubbles during continuous use by a person sleeping on the mattress pad. 4. The insulated mattress pad of claim 3 wherein the reflective material is metal foil.
