The plush velour cover is easy to remove and wash. THIS WEDGE CUSHION IS 18" at its widest point, and sturdy enough to keep its shape up to 150lbs. The rounded contours aid comfort by eliminating any sharp joining points that might dig into the skin. TRAVELS EASY TO WHEREVER YOU SIT. The size will accommodate a wide variety of sitting locations, from a plush recliner to a leather car seat to a wooden dining chair to an airplane seat. The molded handle makes it easy to take wherever you need it. SUPPORT AND COMFORT PROBLEM AREAS! Our wedge cushion is designed specifically for redistributing pressure to the hips to reduce coccyx pain. Though it does have some elevation in the back, it is not intended to give an extra inch or two of lift.
