Closing an above-ground pool used to involve heavy boards or messy planks to keep covers afloat. Modern materials have rendered those cumbersome methods obsolete.
Today, high-grade plastics perform the heavy lifting. Choosing the Best Pool Pillows for Winter ensures your cover stays taut while ice expands harmlessly against the air-filled cushion. Check the details below to see which configuration fits your setup.
Key Takeaways
- Prioritize thicker PVC material ratings, as 0.5mm or higher offers significantly better puncture resistance than thinner budget options.
- Match the total surface coverage of the pillows to the specific dimensions of your pool to ensure uniform weight distribution.
- Select designs that include reinforced metal grommets or dedicated rope channels for secure, centered positioning under the cover.
- Consider multi-pack configurations if you have a larger pool, as using several smaller pillows is often more stable than one giant unit.
- Ensure the valve type is dual-locked or Boston-style to prevent the slow air leaks that turn a firm cushion into a useless puddle by mid-January.

The 0.4mm PVC construction holds up well against seasonal temperature swings. Because you are using multiple pillows, a single leak won't compromise your entire winterization setup. Keep in mind that inflating five separate units takes significantly more time than a single large pillow.

The heavy-duty material is designed to resist cracking when the temperature drops. Its square shape is simple to center under a standard circular or oval cover. Just ensure you don't overinflate it, as the air inside needs room to expand when the sun hits the cover.

The included rope makes it easier to anchor the pillow to the pool edges, keeping it from shifting during high winds. While it is quite sturdy, ensure you handle the valve carefully to maintain a tight seal for the duration of the season.

The Boston dual valve makes it much faster to inflate and deflate than standard small-aperture valves.
The sturdy ropes allow for precise positioning along the length of your pool. It is a solid choice for homeowners who want to minimize the amount of standing water on their pool surface. Be aware that such a large pillow can be cumbersome to manage alone.

Frequently Asked Questions
Do I really need a pool pillow for an above-ground pool?
Yes, if you live in an area that experiences freezing temperatures. The pillow acts as a pressure relief valve by absorbing the force of expanding ice. This simple step prevents your pool walls from buckling under the immense strain of a hard freeze.
How many pillows should I use for a large pool?
For pools longer than 20 feet, a single pillow is rarely enough. You should connect two or more pillows end-to-end to create a central buffer zone. This distribution ensures the ice pressure is spread evenly across the surface.
Why does my pool pillow keep deflating?
Most leaks occur at the seams or the valve due to poor manufacturing or improper inflation. If your pillow goes flat, check for tiny pinholes caused by friction against the cover. Always place a protective layer or soft cloth between the pillow and the cover to reduce wear.
Can I use a standard air mattress instead?
Avoid using standard air mattresses because they are not designed for the harsh, frigid environment of a winter pool. They lack the cold-resistant materials and durable seams necessary to survive the season. A dedicated pool pillow is a much safer investment for your winterization strategy.
Should I place the pillow under or over the cover?
Always place your pillow under the pool cover. It needs to sit directly on the water surface to function correctly as an ice compensator. Placing it on top of the cover will only collect stagnant rainwater and debris.
