ABSTRACT:
A thermal regulating cushioning device includes a flexible, deformable outer membrane and a foam core contained therein having a dimension substantially coincident with the outer membrane. A liquid-like material is sealably contained within the outer membrane and saturates the foam core with the liquid-like material being at least partially circulatable through the foam core. The cooperation of the saturated foam core and the sealable flexible membrane provide a uniform, thermal regulating medium and structural support such that the cushioning device is readily, uniformly deformable when a load is applied thereto.
