  • Great protection for your pool!
Color: 21 FT
This pool liner pad works perfectly! It provides a nice protective layer under the pool and helps keep the bottom smooth and comfortable. It was easy to lay out and fit well without any issues. The material feels durable and does a great job of protecting the liner from rocks, roots, or uneven ground. It definitely gives peace of mind and helps extend the life of the pool. Overall, a great investment for anyone with an above-ground pool—highly recommend! ... show more

  • Nice pool liner!
Color: 18 FT
Looks great under my above-ground pool. It was easy to put down and adds a nice layer of protection for the liner. Very happy with it.

  • Game changer for keeping the liner clean and protected
Color: 18 FT
I've consistently put up a pool each season for the past 4 years. This year, I added the pool liner for our 18 foot pool. As you can see in the picture, the liner pad (blue) fits well under the pool with a little excess still showing. It help up very well all summer. As we just took our pool down, I was pleasantly surprised at how well the liner pad protected the pool liner from debri, sand, and any abrasions. Being a tarp like material, its also very easy to clean. While the description says "pool liner pad," there is no actual padding. You are purchasing a thinner plastic tarp material that is well trimmed to size for your pool. It doesn't add any cushioning, but it does protect from dirt, abrasions, and grass or sticks that might otherwise more easily poke through the pool liner. I would recommend this for an above ground pool. I plan on using this product for now on. ... show more

  • Thin But Works
Color: 18 FT
Just what we needed for under our above ground pool. While peeling the sticker off from shipping, a small area peeled off and had to be patched.

Held up all season. Kept my pool liner “safe”. Buy a size or two larger than pool size.
