The 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 cushions 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.Note: The cushions are shipped compressed. Minor creases or bends upon arrival are normal and do not indicate a quality issue. Simply tap the cushions and allow them to sit for about 48 hours, or use a low-heat dryer for 10–15 minutes to help them return to their original shape. Any wrinkles will gradually disappear with regular use.
