Pressure Relieving Cushion

No one knows more about comfortable driving than long-haul truckers... and this is their cushion of choice! The WonderGel Extreme Seat Cushion offers therapeutic support and amazingly comfortable pressure relief. The secret is the exclusive "column-buckling" gel technology. As pressure increases, WonderGel columns buckle, distributing your weight to neighboring columns, virtually eliminating pressure points. Fits most automobile and household seating. Includes washable, black zippered cover with a non-skid base and carrying handle.
