How do you stop freezing water from cracking your pool walls this year? Expanding ice acts like a slow-motion wrecking ball against your equipment.
Using the Best Pool Pillows for Winter redirects that immense pressure away from your pool sides. A simple air-filled cushion acts as a shock absorber. Pick the right size, and you protect your investment until spring returns.
Key Takeaways
- Prioritize thick PVC material of at least 0.5mm to prevent premature punctures from debris.
- Match the physical dimensions of your pillow to your pool shape for effective pressure distribution.
- Ensure the inclusion of corner grommets or heavy-duty ropes for secure, centered positioning under the cover.
- Opt for multi-pack configurations if you have a larger pool surface area that requires multiple compression points.
- Check that the seams are reinforced, as these are the most common failure points during harsh temperature drops.

Frequently Asked Questions
Do I really need a pool pillow if I have a mesh cover?
Mesh covers allow water to seep through, meaning ice can form directly on top of the cover. A pillow helps create a tapered shape that encourages water and snow to drain away from the center. Without it, the weight of the ice can damage your pool walls.
What should I do if my pillow leaks during the winter?
You have two choices: replace it or patch it. If the leak is small and near the top, a vinyl repair kit might hold until spring. If the leak is substantial, remove the pillow to prevent it from tangling under your cover.
Can I use two smaller pillows instead of one large one?
Yes, using multiple pillows is often safer for large or oddly shaped pools. Tie them together with nylon rope to keep them positioned in the center. This approach provides better distribution of pressure across the ice surface.
Is it better to use a pillow with a specific shape?
Round or square pillows are the industry standard for most residential pools. However, wedge-shaped pillows are useful for specific deck configurations where you need to guide water toward a drainage point. Stick to standard shapes unless your pool design dictates otherwise.
How long do these pillows typically last?
Expect a quality pillow to last one to three seasons. Sun exposure and fluctuating temperatures eventually cause the vinyl to lose its elasticity. Inspect the material for signs of thinning or brittle edges every time you open your pool.
