The back panel (3249-3200-xxx) is essential for equipping a SWINGBO^® wheelchair with the new, contoured "HOGGI align" back cushion (3249-7200-346). The anatomically shaped backrest contour provides pressure relief for the spine and additional support. For optimum sitting comfort, we also recommend using the contoured seat cushion, which stabilizes the pelvis in an upright position and also relieves pressure on vulnerable parts of the body.
