The ENHANCER is an anatomically pre-shaped ROHO air cushion that helps direct your pelvis into the back well and guides your thighs into the leg channels. This gives you greater sitting stability, especially if you have issues with leg or thigh control. The multiple cell heights are contained within two independent inflation compartments (one for the ischial well and leg trough, the other for the lateral and medial thigh supports). This helps to keep your pelvis and legs in position, while still providing optimal skin and soft tissue protection. The ENHANCER also includes the option to offload your ITs.
