Do You Really Need a Pool Pillow? Here’s Why It Matters

You’ve probably seen those inflatable things floating under winter pool covers and thought, “Do I actually need that?” That’s the pool pillow, and yes, it serves more purpose than just taking up space. Whether you’re closing your pool for the season or trying to prevent damage from ice and snow, the pool pillow can be a surprisingly valuable part of winter maintenance.

What Is a Pool Pillow?

A pool pillow is an air-filled vinyl pillow placed in the center of your above-ground pool before you add the winter cover. It’s usually square or rectangular and inflated just enough to stay firm but not overly tight. It floats under the cover all winter long.

Why Pool Pillows Actually Matter

Pool pillows are more than just a piece of pool gear. Here’s why they matter:

  • Ice expansion protection: When water freezes, it expands. Without a pillow, the ice can push out against your pool walls, possibly leading to cracks, warping, or major damage. The pillow absorbs the pressure.

  • Helps water drain better: The pillow keeps the cover slightly elevated in the middle, so water and snow slide toward the edges. This makes cleanup easier and reduces strain on the cover.

  • Prevents cover collapse: A sagging cover can rip or fall into the water. With the pillow lifting the center, it reduces this risk.

How to Set Up a Pool Pillow

Using a pool pillow the right way is easy:

  1. Inflate the pillow to about 60-80 percent so it has some give and won’t pop.

  2. Place it in the center of the pool using string or a pillow loop kit to keep it in place.

  3. Add the winter cover gently over the top, making sure the pillow stays centered.

  4. Secure the cover tightly using a cable and winch or clips.

Can You Skip It?

Some pool owners do skip the pillow, especially in warmer climates where freeze damage is less likely. But if you live somewhere that gets ice and snow, skipping the pillow can cost you. Replacing a damaged liner or cracked walls is a lot more expensive than using a ten-dollar pillow.

What to Do If Your Pillow Pops

If the pillow deflates during winter, don’t panic. Your cover might sag a bit, and ice won’t be redirected as effectively, but your pool isn’t instantly doomed. Still, it’s worth checking your setup and replacing the pillow next season.

Pro Tips to Get the Most Out of It

  • Use duct tape or patches to reinforce seams before inflation.

  • Buy a dual chamber pillow for extra protection.

  • Use a winter cover pump to keep water off the surface.

  • Store the pillow in a cool, dry spot during the off-season.

The Bottom Line

If you’ve been on the fence about pool pillows, here’s the deal: they’re cheap, easy to use, and they can help you avoid major headaches in spring. If you live in a colder climate, they’re worth having in your winter setup.

Taking 10 minutes to set one up now could save you from major repairs later. And when you’re opening your pool next season without a scratch or tear, you’ll be glad you didn’t skip it.
