ABSTRACT:
An inflatable device with an outer inflatable structure, inflatable interior frame, an interior opening and an outer opening. The frame has a plurality of side rods, a center wall, a plurality of interconnected ribs and a plurality of air passages. The interior opening is on a rib and receives any common air pump. The interior frame becomes rigid upon inflation and, forces apart the walls of the outer inflatable structure. Once the interior frame is completely inflated, it provides support to the outer inflatable structure so that the main air chamber inside of the outer inflatable structure does not need to be fully inflated with air. A cap placed over the outer opening is fitted with an air pump valve in order that additional air may be pumped into the main air chamber to increase the firmness of the inflatable device.
