The outdoor cushion covers are made from 100% polyester fabric with a durable UV-resistant coating, providing water resistance, sun protection, and fade resistance—perfect for outdoor use. Adjustable straps help keep the cushion securely in place, while the seat cushion cover also features a non-slip latex bottom to prevent slipping. The patio cushion covers are equipped with hidden YKK zippers for easy removal and cleaning, and double-stitched seams enhance durability, preventing water from seeping through. Piped edges on both the seat and back cushion covers maintain a structured, polished look even after long-term use. This set is suitable for patio chairs, outdoor dining chairs, sofas, benches, and various other seating arrangements, making it versatile for a wide range of outdoor settings.
