The PerFORMer Amputee offers superior targeted pressure relief. This cushion is equipped with a solid seat insert designed for an amputated leg. The majority of weight is distributed along the femur where there is very little bony prominence to maximize comfort over an extended period of use. The ischial and coccyx areas are submerged in the 2" reservoir of lightweight gel, which puts very little pressure on vulnerable areas. Available in multiple models to perfectly accommodate either leg.
