Our patio seat cushion or D cushion is a great addition to any patio or fan cave bar chairs or any standard chair. This cushion is made from 100% polyester for a bright color and durability for either indoor or outdoor use. Seat cushion is filled with a 100-percent polyester fiber sourced from North Carolina and filled right here in Nebraska. Attached ties keep the D cushion securely tied to your chair or patio furniture, 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. Measures 20-inches long x 20-inches wide x 3-inches high. Does not include a chair, cushion only.
