Abstract: An adjustable compact check valve for a pneumatic self-inflating mattress. The compact check valve includes a preload selector which is adjustable to user selected settings, each of which will vary the load on a preload compression spring, to thereby vary the pressure at which the check valve opens. Such adjustment allows a user to vary the firmness of a self-inflating mattress to which the compact check valve is affixed. The compact check valve also has a fully closed position, where air cannot enter or leave the self-inflating mattress, and a fully open position, where air can enter the self-inflating mattress to allow it to fully inflate, or where a user can compress the mattress for storage, by expelling air from the self-inflating mattress. Once air has been expelled from the mattress, the compact check valve may be closed, to prevent inflation of the mattress.

Abstract: A self-inflating stowable bed. The bed includes one or more self-inflating chambers, with each of the self-inflating chambers having one or more polyurethane foam sections therein, with the chamber defined between a first air impervious layer and a second air impervious layer. The self-inflating bed may be evacuated by a household or shop vacuum, and then sealed, rolled or folded, and easily stored or shipped. The polyurethane foam sections may be provided with different members having different indentation force deflection specifications suitable for bed portions and edge of bed portions.
