The Ignite Medium rigid carbon back supports are designed for the active user who requires a lightweight back support with some lateral contouring to enhance self-propelling efficiency as well as offering more positioning support. Ignite back supports feature the unique bubble contour technology which reduces foam tension combined with a soft Sunmate Viscoelastic foam overlay assisting with increased immersion & pressure redistribution. The Medium depth lateral support enhances trunk stability, encourages a midline sitting position & is width & angle adjustable for a perfect fit.
