Pool Pillows for Above Ground Pools 4x15 FT, Heavy Duty Winter Pool Pillow for Winterizing - 0.5mm Thick PVC, Reduce Ice Pressure & Pool Cover

• PROTECT YOUR POOL IN WINTER: Protect your above ground pool during winter with our pool winter pillow. It absorbs pressure caused by freezing and expanding ice, reducing stress on pool walls and helping reduce the risk of pool wall cracking during ice formation. Pool pillows for closing winter support the pool cover and keep the center elevated, reducing the buildup of leaves, rainwater, and snow on top
• BUILT TO LAST CONSTRUCTION: Made from 0.5mm thick, flexible PVC with reinforced, double-sealed wide edges, this pool cover air pillow is built for enhanced air retention and long-term use. Thickened material and reinforced sealing structure help resist air leaks and tearing under pressure. Engineered to perform in extreme outdoor conditions, from -10°F to 180°F, it delivers dependable protection for winterizing your pool
• DUAL-VALVE DESIGN: Double-layer valve helps prevent air leakage and maintain stable inflation all winter long. Compatible with most standard air pumps, this pool balloon for closing pool is easy to use. Inflate to 70–80% to allow enough compression space as ice forms. Features 2 separate caps for easy inflation and deflation
• CENTERED POSITIONING: With 4 reinforced grommets and the included 2 × 33 ft ropes (can be cut to fit pool size), the air pillow for above ground pool can be easily secured in the center of the pool. Keeps the pillow in place and distributes pressure more evenly as ice forms
• WIDE COMPATIBILITY: The 4x15 pool pillow is suitable for above ground swimming pools, including round, oval, and rectangular shapes. It can also be applied for seasonal protection of outdoor furniture, helping support covers during winter storage and harsh weather conditions
