Air cushion for pool 4′ × 15′ – Special large winter covers

Designed for large pools, the 4′ × 15′ air pillow (≈ 1.22 × 4.57 m) slips under the winter cover to form a light arch. This slope directs rain, meltwater, and debris toward the edges rather than accumulating in the center, which reduces the load on the cover and limits ice pressure on the walls.
Ideal for above-ground pools (round/oval) and setups requiring a long air pillow, it installs in minutes and is reusable season after season. Available in multiple sizes depending on pool dimensions.

Key points

• Long size: 4′ × 15′ (≈ 1.22 × 4.57 m) — perfect for large covers

• Reduces water/snow accumulation in the center of the cover

• Reduces ice pressure on the cover and structure

• Facilitates opening in spring and winter maintenance

• Quick installation and reusable

• Compatible with most above-ground pool winter covers

Usage (quick)

1. Inflate to ~60–70% (the pillow should remain compressible to absorb expansion).

2. Position in the center of the pool; secure if necessary (fasteners/cords).

3. Deploy the winter cover over it and secure.

4. Periodically check alignment and air level during the season.

Pro tips

• Avoid over-inflation: an overly rigid pillow absorbs expansion less effectively.

• For very wide pools, combine a long air pillow with an additional size to optimize the slope.

• Use a cover pump or a siphon to remove water accumulated on the cover.

Compatibility

• Above-ground pools (round and oval).

• Works with most cable/winch systems and winter pool covers.
