The Maddak Corner Seat/Positioning Aid is made to be used anywhere – indoors, outdoors, or even in the bathtub – to help children with head and upper extremity control. It stabilizes the shoulder, pelvis, trunk, and also brings the arms and shoulders forward to increase arm movement. This also allows the child to work on activities. This seat features an H-strap for anterior trunk support, a hip belt to maintain proper position, and an abductor block to help maintain leg extension and reduce extensor thrust. The broad base also means it won't tip over.
