Many assume these simple air cushions are an optional accessory for closing a pool. In reality, they act as the structural backbone for your cover, absorbing the crushing expansion of freezing water.
Finding the Best Pool Pillows for Winter is a tactical decision for protecting your investment. Getting the right size and thickness ensures your cover survives the thaw. Read on to compare how these heavy-duty options handle the seasonal freeze.
Key Takeaways

Frequently Asked Questions
Do I really need a pool pillow if I live in a mild climate?
If you live in an area where the water rarely freezes, you can probably skip the pillow. They are designed specifically to absorb the pressure of expanding ice against your pool walls. However, if your area experiences occasional hard freezes, a pillow serves as cheap insurance. It is a small investment compared to the cost of repairing a cracked pool wall.
How do I keep the pillow from floating away?
Use the grommets to tie the pillow to the pool cover or the wall anchors. Use nylon rope rather than plastic string, as it holds up better against UV rays and moisture. Some people prefer to use heavy-duty bungees. These provide a bit of give, preventing the ties from snapping if the pillow shifts under a heavy snow load.
Can I use a regular air mattress instead?
Avoid using standard air mattresses or pool floats. These are made of thinner materials not designed to endure months of freezing and thawing cycles. They will almost certainly pop or deflate within a few weeks. You need a dedicated winter pool pillow built with cold-resistant vinyl.
Should I put the pillow under or on top of the cover?
Always place the pillow under the pool cover. This allows the pillow to sit directly on the water surface. When ice forms, it pushes against the pillow instead of your pool walls. Placing it on top of the cover offers no structural protection for your pool frame.
How long do these pillows usually last?
Most owners get one to two seasons out of a quality pillow. Check for small pinhole leaks every time you reinstall it. If you store your pillow in a cool, dry place away from sharp objects during the summer, you can extend its life. Always clean and dry the surface before folding it for long-term storage.
