For use by children aged 1 to 4. It is good, it doesn't slip inside compared to another one we had before. It needs a lot of water to fill up. Unfortunately, the one we bought had a small hole and it leaks water. You can't fix it where it is (on the floor). From the store, I didn't see much intention to exchange it. For such a large pool, maybe you should also get a filter, it's a waste of water.
