The ARDEN 2-Pack Outdoor Dining Chair Cushion is crafted with durable outdoor polyester fabric featuring PFAS-Free C0 water-resistant treatment and a partially recycled polyester fill for long-lasting comfort. Designed to be eco-conscious and skin-safe, this patio seat cushion provides a supportive and family-friendly seating upgrade for your deck, porch, garden, or backyard dining space. This highback outdoor chair cushion measures 20 in W x 44 in H x 3.5 in T, with a 20 in x 20 in seat cushion and a 20 in x 24 in chair back for full dining chair coverage. The fade-resistant outdoor fabric helps your patio furniture look vibrant season after season, even with continued outdoor use. The C0 water protection finish helps repel moisture while maintaining a soft, comfortable feel. Cleaning is simple—just use mild soap and water for quick, low-maintenance care. Four sets of fabric ties keep the cushion securely in place on outdoor dining chairs. Inside, the partially recycled polyester fill helps the cushion retain its shape and deliver lasting support for everyday lounging and entertaining. While this outdoor cushion is both UV-resistant and water-resistant, we recommend bringing it indoors during heavy rain or when not in use to extend its lifespan and keep it looking its best.
