ABSTRACT:
A self-inflating air mattress includes an air chamber and a foam panel therein. The air chamber is defined by top and bottom sheet panels and a valve allowing air passage into and out of the air chamber. The foam panel includes apertures therethrough, and the top and bottom sheet panels are mechanically coupled directly together via the apertures in the foam panel. As a result, the foam panel need not be mechanically connected to the top and bottom sheet panels and improved air flow within the chamber results. Furthermore, by virtue of the direct mechanical coupling between top and bottom sheet panels distributed throughout the air mattress, the top and bottom sheet panels are limited in their relative spacing and the air mattress tends to better support any weight placed thereon, there being no pillowing of the air mattress in response to weight placed thereon.
