In very good used condition. Has a mild contour. See photos for more measurements. The covers are removable and washable. Includes clamp hardware that attaches to a wheelchair back rest vertical poles. This rigid back has adjustable mounting height, angle, and width. It was previously mounted to a 17″ wide wheelchair but width is slightly adjustable. This item only includes the pieces shown in the pictures.
