Durable square pool pillow designed to protect above-ground pools during winter. Made to withstand cold weather and help prevent ice damage. Features: Uses sealing technology and textured, cold-resistant material to evenly distribute internal pressure. Enhances compression resistance and durability, making it ideal for long-term use in freezing conditions. Promotes outward ice expansion, preventing internal ice buildup from pushing up and damaging pool walls. Effectively avoids cracks, bulges, or structural deformation caused by freezing temperatures. Equipped with a dual-fold valve design that allows air to inflate or release up to 10 times faster than standard valves. Enables quick setup and storage, ensures a tight seal, and reduces the risk of air leakage. Each corner features a reinforced ring for attaching the included 15m rope. Securely anchors the pillow to the center of the pool, preventing displacement from wind or water movement during winter months. 120x120cm size provides broad coverage to effectively absorb ice pressure across the pool surface. Ideal for medium to large above ground pools requiring reliable winter protection.
