Subakvo Above Ground Pool Air Pillow 6 ft Round — Winter Closing Cushion, Cold-Resistant Vinyl & Centering Rope

Subakvo 6 x 6 Ft Air Pool Pillow is an inflatable winterizing cushion designed to protect above-ground pool walls by absorbing ice expansion and keeping winter cover material clear of standing water and debris.

When closing an above-ground pool for the season, a properly sized air pillow reduces pressure on the pool wall caused by freezing and thawing. The Subakvo pillow is made from a flexible cold-resistant vinyl, includes corner grommets and a centering rope, and is sized to fit standard 6-foot round pools. It’s simple to inflate and store, providing a practical, low-effort addition to your winter pool kit.

How does this air pillow protect my pool during winter?

The pillow sits beneath the winter cover and fills the center of the pool, creating a cushion that lets ice expand inward rather than against the pool walls. This reduces the risk of warped or bowed walls and helps the cover shed rain and snow. The pillow’s flexible vinyl material absorbs pressure and returns to shape when thawed.

• Creates inward expansion space for freezing water
• Lessens direct pressure on pool walls and liner seams
• Helps prevent water pooling on the winter cover

How durable and weather-resistant is the Subakvo pillow?

Constructed from 0.40mm (27 gauge) vinyl, the pillow balances flexibility with long-term wear resistance. The material is formulated to remain pliable at low temperatures so it won’t crack or become brittle through seasonal cold. Proper inflation—about 70–80%—reduces stress on seams and extends service life.

• 0.40mm vinyl resists tearing and UV degradation during storage
• Cold-tolerant composition keeps the pillow flexible in freezing weather
• Recommended partial inflation avoids seam strain and over-stretching

What features make installation and centering easy?

Subakvo includes grommets at the four corners and supplies a centering rope so you can position the pillow quickly under the winter cover. The grommets prevent rope chafing and keep the pillow from shifting as the cover tightens. The pillow inflates fast with a standard pump and cleans easily before storage.

• Four reinforced grommets for secure rope attachment
• Centering rope included for fast, accurate placement
• Simple inflation and low-maintenance cleaning

How should I inflate and care for the pool pillow?

Fill the pillow to about 70–80% of capacity to allow room for ice expansion and to avoid over-stressing the seams. After use, rinse off chemicals and debris, let it dry fully, then fold and store in a cool, dry place away from sharp objects and direct sunlight. Replace the pillow if you notice significant punctures or seam damage.

• Inflate to 70–80%—do not overfill
• Rinse and air dry before storing folded
• Inspect for punctures or seam weakening each season

Who is this product for? Homeowners with 6-foot round above-ground pools who want a straightforward, low-maintenance component for winterizing. It’s ideal for people who prefer a durable, cold-resistant inflatable to reduce winter wall stress and minimize water pooling on covers. Installers and seasonal pool caretakers will also appreciate the included grommets and rope for quick, repeatable positioning.
