Replacement SET-811 Circular Modular Deep Seating Cushion. Custom made cushion fit to our Circular Modular Collection. Set includes 4 seat Cushion + 8 Back Cushion (Pillow). The seat cushion comes with Premium High-Density Polyurethane Foam, wrapped with Polyester Dacron Batting for extra padding and covered with Weather-Resistant 100% Solution-Dyed Polyester by Sunbrella. The seatback cushion is a fiber-loose poly pack so it's not as firm as the seat but it will still maintain its rigidity. Each cushion is made to order using 100% new materials. Please note that production time is approximately 2-3 weeks.
