This product is specially designed with removable bottom support stays so the seat will conform to molded, contoured canoe seats. Straps with quick-release buckles securely attach the chair to most canoe seats; it detaches quickly for use as a camp chair. It features 1" memory foam and a 420D coated ripstop nylon shell. Dimensions: 27" x 15.5". Weight: 1.37 lbs.
