Now with lighter, more rigid, hardware and a simpler, compact profile... The Java Back’s patented biomechanical design provides the flexibility to easily and independently optimize pelvic support and balance the trunk, supporting the normal rhythm and movement of the body. The user experiences comfort and stability at rest, and no interference with function and mobility. The Java Back is most effective when coupled with a Ride® wheelchair cushion to aid in postural control and help reduce risk for tissue injury. The Decaf Back shares all the adjustable features of the Java Back, plus a few extras, to meet the specific needs of growing and developing children.
