The Posture-Mate® HB Overlay by Immersus Health Company turns your sling-seat, high-back wheelchair into a comfortable support system. The unique ergonomic design of this overlay gives you a completely supportive surface for your high-back manual wheelchair. With three seat widths available and a back height of 20 inches (with an additional 12 inches of height from the headrest), the Posture-Mate® HB Overlay can fit most standard high-back chairs with a sling-seat.

What Makes This Different

The Posture-Mate® HB Overlay’s design is comprised of high-specification flexible foam, which allows your pelvis to be immersed in the system, while maintaining positioning throughout your back. The structured seat base provides the hips and thigh area with additional support. The back of the overlay’s construction has lumbar support, which helps with overall spinal alignment and posture while also keeping your back comfortable in the chair. The overlay’s contoured head support is independently adjustable, allowing you to find your ideal comfort and support, while the full arm covers ensure that your arms stay protected and comfortable. 

The Posture-Mate® HB Overlay is simple to put together and secure. Velcro seams allow for easy attachment of the overlay’s segments, while the securement straps keep the back, seat and calf in place while you are in the wheelchair. The calf guard is easy to remove, allowing full access to your wheelchair’s footrest.

Why We Like It

This clinically-proven overlay system has a stretch-cover design which helps contour with your individual shape. This allows you maximum comfort and movability in the system, while assisting in positioning and proper posture. The system’s cover also features a fluid-proof, breathable construction, making it simple to keep clean and hygienic. The easy setup of this system is a breeze to adjust, take off and store with your manual wheelchair.
