Our cushion is made with 100% polyester for great color and durability, it will work great for both indoor or outdoor use. Seat cushions are filled with a 100-percent polyester fiber sourced from North Carolina and filled right here in Nebraska. Attached ties keep the cushion securely tied to your favorite adirondack chair, also works well on a rocking chair. The adirondack cushion is also circle tacked to eliminate bunching of filling for a perfectly comfortable seat. Lightly spot clean or hand wash with a mild detergent and cool water, allow to air dry. When the cushion is laying flat, it measures 45 inches long x 20 inches wide x 3 inches high.
