Above Ground Swimming Pool Winterizing Closing Air Pillow - 4x8

Swimline 4' x 8' Above Ground Pool Air Pillow

Protect your above-ground pool from winter damage with this heavy-duty 16-gauge vinyl Air Pillow. When placed beneath your pool’s winter cover, the Air Pillow helps absorb the pressure caused by expanding ice, relieving stress on pool walls and preventing costly structural damage.

Designed to attract freezing water as it expands, the Air Pillow also helps reduce the accumulation of rain, snow, and leaves on your winter cover—making seasonal maintenance easier. For best results, inflate the pillow only halfway to allow for natural compression during temperature changes.
