Abstract
A multiple chamber self-inflating pad having a fluid impervious first chamber defined by a first flexible panel and an intermediate panel in which a first resilient member is disposed and to which the resilient member is bonded. An orifice is provided to control inflation or deflation of the first chamber. A second flexible panel is selectively bonded to the intermediate flexible panel preferably to form a gap or pocket into which a second resilient member may be removably disposed. Preferably, the first resilient member is an open cell foam while the second is constructed from closed cell foam. Alternative embodiments include the creation of a fluid impervious second chamber either fluidly linked to the first chamber or to the environment, alternative resilient materials, inclusion of radiant barriers, and the like.
