The seat can be adjusted easily and sits really well on the toilet seat. We take the seat with when we go to the grandparents or uncles, and also because it can be attached without any problems. Our little toilet objectors has accepted the seat immediately. That was a good sign. Previous potty and devices were in fact always denied. But here he also keeps longer "sessions" it without whining from. Very practical is the fact that the front part is a little further pulled down into the bowl, so that even with the guys when really pee everything goes in the bowl. Strong buy recommendation!
