Pool Floor Padding, 21ft Round

From what I read in the reviews, it was exactly what I expected. A large round semi thick felt disk. We have a 20 x 20 round above ground and decided to forgo the sand and try this instead. Luckily it works well right on top of the dirt. I had to level the area a little and spend some time grooming the dirt to eradicate all rocks. Once I had it down where I wanted it , I slowly walked on it with bare feet feeling for any missed rocks. I found a few and in the end with the pool up full of water, we love it so far. Its thick enough that it does pad the ground a little, enough to make comfortable on our feet. So for what ever reason you don't use sand, this is a good alternitive.
