A method of making a sleep product having a cooling gel layer includes providing a mold, coating the mold with a composite material including a mold release and a cooling gel, and introducing a foaming mixture into the mold so that the foaming mixture is in contact with the composite material. The foaming mixture is allowed to rise and cure into a foam layer having an outer surface covered by the composite material. The composite material is both a mold release coating that facilitates removing the foam layer from the mold and a cooling gel coating that remains on the outer surface of the foam layer after the foam layer has been removed from the mold to provide a cooling effect at the outer surface of the foam layer.

Polyether- or polyester-epoxide polymer (PEEP) compositions are disclosed. The compositions comprise reaction products of a polyepoxide compound and a polyol composition. The polyol composition has a melting point within the range of 20? C. to 100? C. and a hydroxyl number less than 35 mg KOH/g. The PEEP composition is a solid-solid phase-change material. As measured by differential scanning calorimetry (DSC) at a heating/cooling rate of 10? C./minute, the PEEP composition has a transition temperature within the range of ?10? C. to 70? C., a latent heat at the transition temperature within the range of 30 to 200 J/g, and little or no detectable hysteresis or supercooling upon thermal cycling over at least five heating/cooling cycles that encompass the transition temperature.
