A Seat Harness made from static material to position the pelvis. It is designed to assist in maintaining a neutral pelvis for those with high extensor tone. It helps to control posterior pelvis rotation and anterior thrusting. This item is a front pull version that allows tightening the straps by pulling from the rear of the user towards front of user. The thigh straps secure to any frame location via a supplied 16" strap. This allows alternate positioning and increases the maximum allowable thigh circumference.
