DOCRED 2Pack 4 x 8 ft Square Inflatable Pool Pillow for Above Ground Pools Cold Resistant Winterizing Air Pillow Pool Cover Support Pool Closing Kit with 8 Ropes

Reliable Ice Pressure Protection: Safeguard your above-ground pool through winter with the pool pillow; placed below your winter pool cover, this ice equalizer eases stress from expanding ice to avoid wall damage; it lifts the cover center and reduces buildup of snow, rain, leaves and other debris in off-season.

Thick Cold-Resistant PVC Material: Constructed from heavy-duty thick cold-proof PVC, this winter pool pillow fits long-term outdoor use in freezing weather; reinforced structure prevents punctures, cracks and air leakage, supporting repeated annual pool winter maintenance; comes with 8-piece repair kit for unexpected damage.

Fast Inflation & Deflation System: Built with double-layer Boston valve for quick filling and easy air release after winter; inflate with a compatible air pump (not included); fill to 70%–90% volume to reserve space for ice expansion and achieve ideal protection.

Stable Positioning Design: Use the included rope to fix the winter pool pillow at the center of your above-ground pool; secure the rope to the pool frame to keep the cushion under the cover; proper placement balances ice pressure and stops shifting caused by wind, snow and water flow.

Broad Pool Compatibility: Functions as a winter pool cushion and cover support ice equalizer for seasonal pool shutdown; works with round, oval and rectangular above-ground pools, offering stable support under winter covers to protect your pool all winter.
