The Circulation Improving Seat Cushion

This alternate-pressure inflating seat cushion stimulates circulation and alleviates pressure points in your posterior and legs. Made by a company that supplies the same technology to the U.S. Air Force, the unit's twelve integrated air bags inflate and deflate intermittently, stimulating blood circulation through areas of soft tissue that receive insufficient blood flow during prolonged sitting. The 12-minute, four-step sequence disperses weight evenly across your posterior, relieving point-of-contact pressure and helping to prevent blood vessel and capillary constriction that can lead to pressure sores. Ideal for long flights and road trips, those with sedentary jobs, or someone who is wheelchair bound, the cushion fits in nearly any chair. The cushion's rechargeable battery lasts for 48 hours after a two-hour charge (AC adapter included). 2 3/4" H x 18 1/2" W x 18 1/2" L. (4 lbs.)
