Pool Pillows for Above Ground Pools 4x15 ft - Winter Cover Air Pillow

In this review of the Pool Pillows for Above Ground Pools, the bottom line is simple: this 4x15 ft air pillow is for owners of 18 ft round above ground pools who want a straightforward, durable winterizing aid to reduce liner stress from ice expansion. The reviewer found the pillow useful because its ultra thick 0.4MM PVC resists cold and holds the cover up so water, leaves, and snow gather at the edges rather than in the center. It is a practical winter kit component rather than a complicated accessory, and it earns its place when used as directed.

Key Features

• Size and fit: The 4x15 ft dimension is sized to suit an 18 ft round above ground pool and positions centrally to reduce cover sagging.
• Thick, cold-resistant material: Made from 0.4MM wear-resistant PVC, the pillow is built to withstand low temperatures and resist punctures over winter.
• Air retention guidance: The pillow is designed to be partially inflated (about 60-80%) so it can compress and absorb ice expansion without overpressure.
• Anchoring hardware: Reinforced grommets on all four corners allow simple rope attachment to keep the pillow centered beneath the winter cover.
• Debris control: By holding up the winter cover in the center, the pillow encourages rain, leaves, and snow to collect at the pool edges for easier cleanup.

Who It's For

This product is aimed at owners of above ground pools, especially those with an 18 ft round pool, who need a no-frills winterizing float that reduces liner stress and cover sag. It suits DIY pool owners who prefer to add one protective element to a winter cover without professional installation.

It is not ideal for users who need a custom fit for nonstandard pool shapes or those seeking an inflatable that must be fully airtight and rigid; some customers report mixed air retention over time, so anyone requiring guaranteed long-term inflation without periodic checks should consider alternate solutions.

Pros & Cons

Pros

• Thick 0.4MM PVC offers strong material feel and cold resistance for winter use.
• Reinforced grommets and supplied ropes make it straightforward to center and secure the pillow.
• Simple inflation to 60-80% and placement reduces cover sag and central debris buildup.
• Good value for money for a basic pool winterizing accessory.

Cons

• Air retention is mixed in user reports, so occasional reinflation checks may be required through the season.

Frequently Asked Questions

How much should I inflate the pillow?
Inflate to about 60-80% of capacity so the pillow can compress and absorb ice expansion without overpressure.

Where should the pillow be placed?
Place as close to the center of the pool as possible and secure the corner ropes to the pool edge to ensure even snow and ice distribution.

Will it prevent leaves and snow from entering the pool?
The pillow helps keep the winter cover lifted in the middle so rain, leaves, and snow gather at the outer edges for easier removal from the cover rather than collecting in the pool center.
