Deep seat chair cushion pads combine a seat cushion with a matching back cushion to support a relaxed, deep seating position on indoor or outdoor chairs. High resilience polyester cotton filling helps the seat resist flattening so you stay comfortable longer, while the thick, soft back cushion helps ease waist soreness during extended sitting. Rope belts firmly secure the seat cushion so it stays in place. Sun-proof, oil-proof polyester fabric with removable covers wipes clean for simple care.
