Replacement SET-140 Natsepa Modular Deep Seating Set Cushion. Custom made cushion fit to our Natsepa Modular Collection. Set includes 8 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.
