Closing your pool used to mean tossing a heavy, water-logged slab of vinyl under the cover and hoping for the best. Modern designs now use air-cushioned geometry to prevent ice buildup and protect your pool walls.
Finding the Best Pool Pillows for Winter is much simpler when you understand how these buffers relieve structural pressure. Let’s identify the right options to keep your pool safe through the freeze.
Key Takeaways
- Prioritize pillows constructed from cold-resistant PVC that won't become brittle when temperatures plummet.
- Match the size of the pillow to the surface area of your pool to ensure the cover stays properly elevated.
- Choose models with reinforced grommets to make tying them down securely much easier during winterization.
- Thicker material gauges, such as 0.4mm or higher, provide much better durability against ice expansion.
- Always include extra rope to tie off the pillow so it stays centered under the pool cover all season.
