ABSTRACT:
The specification discloses an inflatable, insulating apparatus for use as or in a mattress inflatable with a fluid such as air. Included are a fluid-tight envelope and reflective material, preferably thin layers of metallic material, on at least two spaced portions of said apparatus to reflect thermal radiation, such as from a supported living being when the apparatus is used as a mattress, to reduce radiative heat transfer across or through the structure. Either as an alternate insulator, or in combination with the reflective material, one or more baffles may be provided within the apparatus to reduce both free and forced convective heat transfer. In one embodiment, reflective baffles form a honeycomb assembly which is collapsible upon deflation of the structure.
