✅【High Quality Materials】This 4ft diameter (before inflation) round above ground pool pillow is made of 0.3mm thick cold resistant PVC material and can be used with confidence even in temperatures as low as -10° F (-25° C).
✅【WINTER PROTECTION】Swimline air pillows serve as 'ice compensators', absorbing the pressure from freezing and expanding water, ultimately protecting your pool and cover from winter damage.
✅【Including Fixing Cord】The winter pool pillow has 4 holes at the edges, which can be fastened to the center of the pool using the cord included with the product. This ensures that the inflatable pillow does not move around in the water, that the pressure of the ice cubes on the pool is evenly distributed when it freezes.
✅【Wide application】Not only can be used for various types of above-ground swimming pools, but also can be used with protective covers for winter protection of outdoor fountains, spas and other furniture.
✅【User-Friendly】Inflating this above ground pool pillow is simple; just utilize a standard household electric air pump for quick setup. After inflating, secure it in the center of the pool by attaching the ropes to the four holes located at the edges of the pillow.
