Abstract
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.
