Many pool owners assume that winterizing is just about throwing a heavy tarp over the water and hoping for the best. That cold-weather neglect often leads to structural damage that costs far more than a simple piece of plastic.
The right equipment acts as a buffer against expanding ice, protecting your pool walls from undue pressure. Picking the Best Pool Pillows for Winter is a small step that prevents a massive headache come spring. Keep reading to see which configurations handle the freeze most effectively.
Key Takeaways
- Prioritize pillows constructed from 0.4mm or thicker PVC to ensure they resist punctures and seasonal temperature drops.
- Select a size that fits the surface area of your pool, as a pillow that is too small fails to displace enough weight.
- Look for reinforced grommets or dedicated center loops, as these make anchoring the device to the pool floor much easier.
- Always confirm if the package includes a securing rope, because keeping the pillow centered is essential for even pressure distribution.
- Consider purchasing multi-packs if you own a larger pool, as using multiple smaller pillows often provides more reliable coverage than one giant air bladder.

Frequently Asked Questions
How much air should I actually put inside the pillow?
Inflate the pillow until it is about 60 to 70 percent full. If you fill it to maximum capacity, the pillow will have no room to compress when ice forms, which leads to popped seams and expensive replacements.
Do I really need a pillow if I have a mesh safety cover?
Mesh covers allow water to pass through, so you do not necessarily need a pillow to manage water weight on the surface. However, a pillow still helps prevent ice from damaging your skimmer and pool walls by absorbing the expansion force in the center.
What should I do if my pillow loses air mid-winter?
Unfortunately, a deflated pillow offers almost no protection against ice damage. You should try to drain the pool cover of snow and water regularly to relieve pressure, and plan to replace the pillow during the next off-season.
Can I use two smaller pillows instead of one large one?
Using two pillows is often a smarter strategy for larger or irregularly shaped pools. Tying them together in the center provides more stability and ensures the ice expansion is funneled toward the middle rather than pushing against your expensive pool liner.
How do I secure the pillow so it stays in the center?
Use nylon rope threaded through the provided grommets to anchor the pillow to the sides of your pool. Ensure the tension is even on all sides so the pillow does not drift toward the edges where it could cause stress on the pool walls.
