Customer Reviews
Pool cover seems extra thick and durable

Review by Mark I. PA on Nov 1, 2019 Verified Purchase

First time pool owner, everything has been accomplished by research and careful planning. Pool Factory pool kit made it much easier to figure out what I needed to build our pool and also had everything easily available for when it came time to close it for Winter. Pool cover seems extra thick and durable, dark brown color seems like it may aid in keeping the pool from freezing too deeply when the sun is shining. Seems like another good purchase, thank you.

This winter cover is very good quality!

Review by DeEtte F. Oregon on Oct 28, 2019 Verified Purchase

It is made from very heavy, thick material. We have a 27’ round pool. It was a little challenging getting it on with the air pillows in the middle, but we persevered and got it installed properly.

Easy to put on and well made.
