Blue Wave Gorilla Pad 12'

We have a 12 foot Intex pool and we bought this to put underneath. We were going to put sand under it at first but this seemed much easier and more solid. This pad works great! I am glad we got it because you can feel little rocks at the bottom of the pool but this pad makes them just feel like a little bump and not something hard and sharp that is trying to stab its way through the liner. We are glad we bought this. It seemed expensive but buying sand was going to be more. This pad is really thin but does the job it's supposed to. Worth the investment to protect the pool liner for sure.
