A system providing an improved inflatable cushion of the type comprising two films of a thermoplastic fused together to provide a plurality of inflatable chambers between the films, with each chamber communicating with a central inlet opening through an inlet passageway; and an improved device for filling and sealing such a cushion. The inlet opening for the cushion extends through only one of the films, and the device has a nozzle which directs air into the opening against the portion of the other film which extends across the opening, so that the air will be evenly deflected through the inlet passageways to simultaneously inflate all the chambers in the cushion.
