The J3 back is a highly customizable backrest that can accommodate just about any positioning need you may have. The J3 can be as simple as a mild contour back as short as 6.5” in height or as tall as 24” with a deep contour. You also have positioning options for lateral support, posterior support, posterior and lateral support, or even posterior and deep contour. The J3 can also accommodate mounting hardware for headrests and lateral trunk supports. Four different mounting hardware systems will allow you to attach the backrest to your wheelchair to meet any of your positioning needs.
