Protekt Gel Coccyx Cushion helps in the prevention and treatment of pressure sores. The high density/high resilient foam combined with a gel bladder allows for deep immersion and excellent pressure redistribution. The dual compartment gel bladder eliminates gel migration and the cut-out design removes all pressure on the coccyx bone. The stretch nylon cover is comfortable, breathable and fluid resistant. Safety buckles keep the cushion in place. Weight Capacity: 250 lbs., Size: 18" x 18" x 3".
