This Blue PVC winter pool pillow is essential for protecting your above-ground pool during the cold months. Designed to absorb pressure from expanding ice, snow, and water, it is placed at the center of the pool under the cover, preventing damage to pool walls and liners. Its durable construction ensures it withstands harsh winter conditions and prolonged sun exposure, maintaining its integrity and color season after season. Engineered to resist temperatures as low as -20°C, this pool pillow remains effective even in freezing conditions. The integrated Boston valve allows for rapid inflation and deflation, minimizing air leakage and ensuring a tight seal. With eyelets for secure anchoring using included nylon cords, this pillow stays in place during windy weather or heavy snow. By effectively absorbing ice pressure and distributing weight, this pool pillow simplifies maintenance and ensures a smoother pool opening in spring.
