Hyperzoo Above Ground Pool Pillow, 6 ft Winter Cover Support, 0.5 mm PVC

Hyperzoo’s 6 ft (1.83 m) winter pool pillow is a floating support for above-ground pools, designed to help distribute freeze pressure beneath a winter cover, with 0.5 mm PVC construction.

• Floats beneath the winter cover — helps distribute pressure away from pool walls as water freezes and expands.
• 0.5 mm high-density PVC, over 3X the thickness of typical 0.15 mm material — made to resist punctures, tears, leaks, and seasonal deflation.
• Cold-resistant to -10°F (-25°C) — suited to winter pool closing in freezing conditions.
• Double-layer Boston valve with a wide opening — supports faster inflation with an air pump and easier deflation.
• Four reinforced grommets and an included 50 ft (15.24 m) rope — help keep the pillow near the center of the pool.

When freezing weather arrives, expanding ice, precipitation, and debris can place pressure on an above-ground pool and its winter cover. This pillow floats under the cover as an ice equalizer and cover support, lifting the cover while helping distribute pressure. It is designed as a practical part of a seasonal pool-closing setup for round, oval, and rectangular above-ground pools.

How does the pillow support an above-ground pool in winter?

It floats beneath the winter cover and helps spread pressure from expanding ice away from the pool walls. By lifting the cover, it also helps reduce stress from snow, rain, ice, and debris during seasonal closing. Keeping the pillow positioned near the middle of the pool helps its support work beneath the cover, rather than letting it drift off to one side.

• Designed for use before freezing weather arrives as part of an above-ground pool closing kit.
• Acts as both a winter cover support and an ice equalizer.
• Its floating position places the pillow between the pool water and the winter cover.

What material and cold-weather range does it have?

The pillow is made from 0.5 mm high-density PVC and is intended for winter conditions as low as -10°F (-25°C). Its PVC is over 3X as thick as typical 0.15 mm material, and the thicker construction is designed to help resist punctures, tearing, leaks, and seasonal deflation. These construction details make it suitable for remaining in place through months of cold-weather pool closing.

• Made from PVC for seasonal outdoor pool use.
• The stated cold-weather range extends to -10°F (-25°C).
• Thicker material is intended to help withstand winter use without seasonal deflation.

How do I inflate, secure, and choose a size?

Inflate the pillow to about 70%-80% of its full capacity so it has room to compress and expand as temperatures change. The double-layer Boston valve has a wide opening for inflation with an air pump; close both valve caps securely after inflating. An air pump is not included. Use the four reinforced corner grommets and the included rope to secure the pillow to the pool frame and reduce shifting from wind, water movement, snow, or debris.

This model is the 6 ft (1.83 m) size. Hyperzoo offers five sizes—5 ft (1.52 m), 6 ft (1.83 m), 7 ft (2.13 m), 8 ft (2.44 m), and 11.8 ft (3.60 m)—for different above-ground pool closing setups. The range is intended for round, oval, and rectangular pools; select the size that suits your pool setup.

• Inflate with an air pump, which is not included.
• Allow room for temperature-related compression and expansion by avoiding full inflation.
• Secure the pillow through its corner grommets to help it stay centered.

Hyperzoo’s 6 ft winter pool pillow suits above-ground pool owners preparing a seasonal cover setup before freezing weather, especially those who want a floating ice equalizer with a way to secure it near the pool’s center. It is designed for use beneath a winter cover, not as a pool cover itself.
