Inflatable cushion

Abstract

A portable cushion has a first chamber formed from an upper sheet and a lower sheet sealed to the upper sheet along three edges, and a resealable closure extending between the upper sheet and lower sheet along a fourth edge to create an air-impermeable pocket when the closure is sealed. There is a second chamber formed from an upper sheet and a lower sheet sealed to the upper sheet along three edges, and a resealable closure extending between the upper sheet and lower sheet along a fourth edge to create an air-impermeable pocket when the closure is sealed. The second chamber is connected to one of the three edges of the first chamber along one of the three edges of the second chamber, to form a two-part cushion having a hinge between the two chambers. The cushion can be filled with air by waving each chamber through the air while the respective fourth edge is in an open position, and then sealing the respective closure element when air has entered the chamber.
