Abstract
A bedding system has provision for heating or cooling a person and for applying the heating or cooling only in areas of the bed where the person is located. A sealed three-ply heat transfer and insulating device covers the mattress, below the contour sheet or other covering which comes in contact with the person's body. A wicking contour sheet or other cover may optionally be used, capable of absorbing any condensation on the surface of the three-ply device. Between the lower two plies of the three-ply material is a channeled flow of coolant liquid, at a regulated temperature close to human skin temperature. Above these two plies, i.e. between the middle ply and the upper ply, is a sealed envelope containing slightly pressurized air. A light weight, well-insulated comforter is also recommended to isolate the sleeper from the thermal ambient environment.
