• 【BUILT TO WITHSTAND COLD WINTER TEMPS】 Unlike cheap, flimsy pool pillows, this one is made of highly durable and 0.4mm thicker material. With our patent sealing technique and embossed, cold-resistant material, pressure is dispersed evenly throughout the pillow. This helps your pool pillows adapt and withstand frosty winters. 【PROTECTION FOR YOUR POOL ALL WINTER】 Arock Pool Pillow protects above-ground pool walls and pool covers from pressure caused by expanding ice. Our pool pillow creates surface tension which allows your pool to freeze in reverse i.e outside in vs inside out. This prevents expanding ice along side your pool walls. Also the pool pillow reduces excess rain, snow, and leaves on your winter cover. 【INFLATE & DEFLATE WITH EASE】 Double fold valve, allows 10x faster inflation and deflation compared to traditional valves. The first fold provides air flow into the pool pillow without the loss of air. 【STAYS IN PLACE】 Built with 4 reinforced grommets at corners to keep the pillow in position at the center of the pool –Just slip the included rope through and tie the pool pillow to your pool. 【SAFETY GUARANTEED】 Measures: 4 x 8 Feet, Suitable for Round Pools, Oval Pools and Rectangular Pools.
