POOLHACKER Winter Pool Pillow, 4 x 8 ft Cold-Resistant PVC Support

POOLHACKER Winter Pool Pillow is an inflatable support for winterized above-ground pools, made with 0.5 mm cold-resistant PVC and designed to help protect pool walls and covers from pressure as ice expands.

• Inflate to 50–70% capacity — leaves room for the pillow to compress as ice expands.
• 0.5 mm cold-resistant PVC — designed for use in sub-zero temperatures.
• Double-layer valve and double-sealing construction — designed to resist leaks, tears and deflation through winter.
• Four reinforced grommets and a 50 ft (15.24 m) rope — help keep the pillow centered beneath the pool cover.
• Works with most blowers and inflatable pumps — makes inflation straightforward with common equipment.

When water freezes, expansion can put pressure on above-ground pool walls and the winter cover. This air pillow is made to provide a compressible point beneath the cover while also supporting it, helping reduce the buildup of leaves, snow and dust. It is intended for above-ground pool winterization.

How does the pillow help protect a pool in winter?

The pillow gives expanding ice a place to press and compress, helping reduce the pressure placed on pool walls and the cover. It also acts as support beneath the cover, helping reduce debris and snow buildup and the risk of cover collapse. Inflate it to 50–70% of its full capacity rather than filling it completely.

• Designed for winterized above-ground pools.
• Do not overinflate; leave room for compression.

How can I keep the pillow in place?

Thread the included rope through the four reinforced grommets to center the pillow in the pool, leaving the rope slightly loose. This positioning helps keep the air pillow under the pool cover as part of your winterizing setup.

• Four reinforced grommets are built into the pillow.
• The set includes a 50 ft (15.24 m) rope.

How does it inflate, and what comes in the set?

The valve fits most blowers and inflatable pumps, and the pillow can be inflated and deflated for setup. Its double-layer valve and double-sealing design are intended to help prevent air loss, tearing and deflation through winter, and the PVC is designed for sub-zero temperatures. Close both valve caps tightly after inflation.

• Includes the pool pillow, rope and instructions.
• Materials have been tested against product testing and standardized material specifications.

What size should I plan for?

The supplied size details give two different measurements: the product title identifies a 4 x 8 ft pillow (1.22 x 2.44 m), while the set contents specify a 4 ft x 4 ft pillow (1.22 x 1.22 m). Use the measurement that matches the pillow you receive when planning your pool-cover setup.

• Product title size: 4 x 8 ft (1.22 x 2.44 m).
• Size named in set contents: 4 ft x 4 ft (1.22 x 1.22 m).

This pillow suits pool owners winterizing an above-ground pool who want a compressible support beneath the cover, with a rope and grommets for positioning. Its stated use is pool winterization, with inflation kept below full capacity to accommodate ice expansion.
