PROTECT YOUR POOL DURING ALL WINTER: Our winter pool pillow creates surface tension which effectively protects above-ground pool walls and pool covers from pressure caused by expanding ice.    This prevents expanding ice along side your pool walls.
EXTRA DURABLE: If you're planning to leave this outside during the harsher winter, it must be strong enough.    Our pool pillow is up to the challenge: the pool cover pillow is made of 0.3mm-thick PVC, which means that it won't leak, tear, or deflate.
STAYING IN PLACE: Just slip the included rope through and tie the winter pillow to your pool and the reinforced grommets at 4 corners around the pillow to keep the pillow in position at the center of the swiming pool.
INFLATE & DEFLATE EASIER: Please do not over-inflate,inflated 70-80% of its full capacity would be better for your pool and the pillow.
