ABSTRACT:
In an air cushion table game, such as air hockey, the air bed, which has an upper surface defining a playing surface, comprises a top layer of material having a multiplicity of air jets exhausting upwardly therethrough and arrayed in a substantially uniform pattern over the playing surface of the top layer to form an air cushion and a bottom layer of material disposed below and connected to the top layer. The top and bottom layers define a single plenum extending therebetween and communicating with each of the air jets, the plenum being of unitary one-piece integral blow molded construction. Preferably, the air bed includes a bumper strip defining a boundary of the playing surface upon the air bed, and the air bed, including the bumper strip, is of unitary one-piece integral blow molded construction.
