Features: Restorable rocking chair cushion is packed with vacuum technology for safe transportation. The cushion may appear flat or have slight wrinkles after unboxing. Gently patting the cushion or leaving it uncovered in a dry place for 5 to 7 days helps restore its full thickness. Using a dryer can speed up the recovery process to regain plush comfort for back to school use. Tie on high back chair cushion comes with reinforced straps for stable and reliable fixation. The straps firmly attach the backrest cushion to the seat and prevent displacement even with regular rocking motion. This secure design ensures the cushion stays in place during use and boosts overall safety and comfort for back to school home and outdoor seating.
