ABSTRACT:
An air bed is disclosed comprising an enclosure formed from a flat rectangular bottom panel, a lower vertical panel standing perpendicularly up from the periphery of the bottom panel, an upper vertical panel disposed above the lower vertical panel, a gusset connecting the lower and upper vertical panels, a rectangular top panel removably connected to the upper vertical panel, and a plurality of restraining straps, with one end of each restraining strap connected to the gusset along the left side of the enclosure and the other end of each restraining strap attached to the gusset along the right side of the enclosure. The enclosure has upper level and lower levels separated by the restraining straps. In each level inflatable air tubes are inserted. Each level of tubes includes bolster tubes inserted parallel and adjacent to the sides and ends of the enclosure, and cushion tubes which are disposed laterally across the enclosure in the rectangular space surrounded by the bolster tubes. Each tube has sheathing surrounding it to reduce noise when adjacent tubes rub against each other, and attachment means are used to prevent rotation of the tubes. An air pump provides air pressure to the inflatable tubes through a manifold block having several separate, variably controlled output ports. An air hose assembly connects the manifold's output ports to the various tubes so that certain combinations of tubes receive various air pressures. In addition, the invention includes a single level embodiment.
