The JAY J3 Back Posterior Lateral Contour is a wheelchair backrest that provides moderate contouring for users that require more lateral support. Designed for users with postural or spinal deviations, including wider trunks and narrow hips, narrow trunks and wider hips, or curvatures, the NEW CradleU Lateral technology reshapes the existing contour to match the user. The J3 is designed with a variety of contour depths, support heights, widths ranging from 30.5cm to 66cm, and support shapes to fit almost every user.
