Pool Pillows for Above Ground Pools, 4 X 8 FT Pool Cover Air Pillows Closing Winter Kit, Cold Resistant Winterizing Float Pillow for Swimming Pools - LEETIN, PCP002

• PROTECT YOUR POOL IN WINTER: Winter pool pillows are incredibly helpful for your pool, which can protect your pool from expanding ice and promote even weight distribution. 4*8 FT size would be suitable for 18’ round pool. THICK MATERIAL & NO LEAK IN WINTER: Pool pillow is made of 0.40mm thick high-density cold-resistant material, which can be used for years and prevent air leakage to protect your swimming pool all winter. PUT AIR PILLOW IN THE CENTRAL LOCATION: Positioning your pool pillow as central to the middle of your above ground pool as you can is critical for success. Securing the pool pillow in a central location is the best way to ensure an even snow and ice distribution. The air pillow has reinforced grommets on all four corners. This distribution is vital for protecting your pool liner and walls all winter. MORE PROTECTION FUNCTION: A pool pillow also prevents rain, leaves, and snow from accumulating in the center of the pool. Instead, debris gathers at the pool’s outer edges where you can easily reach and remove unwanted objects. USING TIPS: Pool pillows should not inflate fully. Some capacity must be left to allow for compression when the device absorbs the expansion of ice. We suggest inflate the air pillow to about 60%-80% of its capacity to allow for compression.
