4 x 4 Ft Pool Cover Pillow for Above Ground Swimming Pools. Winter Pool Pillow for Closing | Extra Durable 0.4 mm PVC Resistant Pool Cover Air Pillow (2 Pcs)

Tips: This product does not contain an air pump. Please do not overfill the inflatable pillow.

• ✅【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.
• ✅【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).
• ✅【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.
• ✅【Easy to Use】This inflatable above ground pool pillow is very easy to use, just use the electric air pump that is commonly used in the family to quickly inflate. Then tie the ropes to the four holes on the edge of the pool pillow and fix it in the center of the pool.
• ✅【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.
