Protects the pool during cold weather by distributing the pressure from ice and snow on the pool wall and pool cover, helping prevent ice or snow from accumulating at the center of the cover and reducing the risk of accidents. Easy to use: Inflate with a household air pump and deflate when finished. Inflate the pillow to about 70% to leave space for ice expansion and avoid damaging the pillow. Then use the included rope to secure the pillow in the center of the pool. Reliable materials: Made of PVC with a thickness of 0.3 mm for strength and durability. Designed to resist tearing from ice and to perform in very cold conditions, down to 10 F (25 C). Size and contents: Includes 1 winter pool inflatable cushion (4 x 4 feet), 2 patches to help prevent damage to the winter pool pillow, and a 49foot rope. When not in use, deflate through the valve for compact storage. How to store: After use, release air through the valve, fold the cushion, and store in a dry place. Use scenarios: In ground or aboveground pools with winter covers, to reduce pressure buildup from ice and snow on the cover and walls. In regions with frequent freezethaw cycles, to help prevent damage to pool covers and reduce safety risks. For seasonal pool maintenance during extended cold periods, providing a simple, stowable solution to protect the pool area. Function and performance highlights: Lightweight, portable winter protection that does not require permanent installation. Uses a simple inflating/deflating process with an easy securing method to the pool center. Robust PVC construction designed to withstand winter conditions while maintaining integrity at very low temperatures.
