Perfect, the filter works better than I expected, at least eight adults and four children fit and we had room. It definitely needs something underneath to level the bottom; I put one of those plastic shade mats we use on trees while camping and it worked perfectly. A rug also works if it is big enough, but ours wasn’t, and where the pool was on the rug it leveled perfectly, but where it rested on the rough floor it would not move at all. I assume it will also work perfectly on grass, but I have not tried it. Excellent if you have the space; otherwise choose a smaller model. It takes effort to level the bottom, but it is a one-time thing and you will enjoy the result a lot. Also, I could not find (at least on Skroutz) a cover from the same company and bought one from a different brand with the correct measurements, and it also fits perfectly and keeps it clean and warms the water just enough so it is not cold but is still refreshing compared to the surroundings.
