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

Reliable Winter Pool Protection: Safeguard your above-ground pool all winter with this winter pool pillow; placed under your seasonal pool cover, the ice equalizer eases pressure from expanding ice to prevent wall damage; it lifts the cover center and reduces buildup of snow, rainwater, ice and debris during winterization.

Thickened Cold-Resistant PVC: Constructed from heavy-duty thickened cold-resistant PVC, this pool cover support pillow withstands frigid temperatures through long winter storage; reinforced material resists punctures, tears, leaks and air loss for repeated seasonal use; comes with 4-piece repair kit for unexpected damage.

Double-Layer Boston Valve Design: Built with a double-layer Boston valve to enable quick inflation and simple deflation after winter; use a compatible air pump (not included); inflate to 70%–90% capacity to leave room for ice expansion and achieve ideal protection.

Secure Centering with Fixing Ropes: Includes 4 durable 20ft ropes to position the pillow at the center of your above-ground pool; attach ropes to the pool frame or edge to hold it steadily under the cover; centered placement evenly distributes ice pressure and prevents shifting from wind, water and snow.

Broad Pool Compatibility: Works as an ice equalizer and pool cover support for winterizing above-ground pools; compatible with round, oval and rectangular models; delivers stable support under winter covers to prolong the service life of your pool and cover.
