An inflatable seat cushion featuring a unique air flow system which controls the flow of air between two separate compartments. In one mode, the air is allowed to circulate from the left side of the cushion towards the right side and vice versa, as the user's weight shifts from one side to the other or, in the alternate mode, the air is locked inside each of the two compartments which provides for a firmer cushion.
