Abstract: Two plastic sheets are selectively joined to create parallel air cells with connecting passageways at alternate ends. The sheets form a mattress for full body, back or leg massages. An air pumped reservoir supplies air flow to a fluidic switch. Air from a right arm pushes air to a left leg and sequentially fills a first cell. Alternating passageways at opposite ends of cells sequentially fill the cells. After the last cell is filled, air flowing out from the last cell through a right arm of the switch pushes the supplied air flow to a right leg of the switch for exhaust, emptying the cells. The cycle repeats automatically, sequentially filling the cells and pushing blood toward the heart and then emptying the cells then sequentially filling the cells.
