Welcome to the store! 1. Protect your pool: Cold outdoor weather in winter can cause pool water to freeze, and our pool pillows can help you distribute the pressure of ice on the pool walls. It is recommended to inflate the pool pillow to 70 percent to allow room for the expanding ice, to avoid ice damage to the pool. Covering the pool with a pool cover can also prevent snow or rain from accumulating in the middle of the pool cover, which can cause it to collapse. 2. PVC material: This round above-ground pool pillow with a diameter of 4 feet (before inflation) is made of 0.3mm thick cold-resistant PVC material, which can be used with confidence even at temperatures as low as -10℉ (-25℃). The edge of the pool pillow has a double seal, making it less prone to leaks or tearing from ice. It will be the perfect companion for your pool! After inflation, the diameter is approximately 3 feet and the height is 1.9 feet. 3. Inflatable pillow with tie rope: The package includes a 15-meter long tie rope, which is perfect for securing the pool pillow in the center of the pool. Preventing the water tank from moving on top of the water tank and evenly distributing the ice pressure on the tank can effectively prevent rainwater, snow, and ice from accumulating in the middle of the tank, leading to the collapse of the tank cover. 4. Easy to use: This inflatable pool pillow is very easy to inflate, and you only need to use a pump or a household electric air pump to quickly inflate it. Then connect the rope through the four holes on the edge of the winter air pool pillow to the center of the pool for quick installation. Note: It is recommended to inflate the inflatable pillow to 70%. 5. Wide range of uses: It can not only be used for various types of above-ground pools, but can also be combined with protective covers for winter protection of outdoor fountains, spa centers, and other furniture. Avoid damage to outdoor facilities due to the accumulation of rainwater, snow, and fallen leaves, and help keep outdoor furniture clean.
