Round Inflatable Pool Winterizing Air Pillow

You pull back the cover in spring and find an ice-damaged wall. That's the repair you wanted winter closing to prevent. This air pillow sits beneath your above-ground pool cover, adding a compressible buffer to help relieve expanding ice pressure before it becomes your problem.

Freezing water expands. Your pool walls shouldn't have to take all that force. The air-filled cushion flexes and compresses as ice presses against it, giving that expansion somewhere to go and helping reduce strain on the structure you've worked to maintain.

A sagging cover gives rainwater and melted snow somewhere to collect—and that weight adds up. Positioned beneath the center, the round pillow raises your cover into a slope to help water move toward the edges. It's support where an unsupported cover needs it.

Your winter buffer needs to stay pliable when temperatures fall. Cold-resistant PVC lets this cushion flex in freezing conditions, while double-sealed edges and a secure anti-leak valve help retain the air it relies on. Those details serve a purpose: keeping your buffer ready to compress.

You put the work into your backyard all summer; you take closing it just as seriously. Adding support beneath the cover is part of protecting what you've built, not dressing it up. With 3,720 customer reviews and 90-day free returns, you have more than a product photo to weigh up.

Wait until the water freezes and you've missed the chance to put this buffer in place beforehand. Add it to your pool-closing plans before the first freeze. At $29.99, it's a practical preventative step toward protecting your pool walls and cover—not another repair to face in spring.
