ABSTRACT:
Disclosed is an air mattress apparatus. The apparatus includes a pump contained within an inflatable chamber. The pump is in fluid communication with the inflatable chamber via intake and exhaust ports. One-way valves positioned on the intake and exhaust ports of the pump control the flow of air from the pump to the inflatable chamber of the air mattress. The pump contains a resilient, closed-cell foam pump material. The mattress is inflated by repeatedly compressing the pump material and then permitting it to expand and fill with air.
