First time to use a pad. We have a 24 foot round pool. The pad was probably more like 26 foot diameter so it extended up the side a little way. We found out later that it should go under the outer ring of the pool. Although really thin, I can see how it would protect the bottom of your liner.

This was easy to put down and adds a layer of comfort under the bottom of the pool. We’ll see how it looks after the pool comes down in the fall.

This product was a huge disappointment. The seam was not sewn currently which caused severe bunching (pad couldn't lay flat! There were large holes and the pad was easy to pull apart! Sadly by the time we got the area ready for the pool, we were past the 30 days to get a refund.
