What I really liked that 2 different heights of the step and the Einklemmmöglichkeit are (The seat is anchored under the toilet seat. It sounds complicated, but is very easy to use) My little daughter is now 1.5 and can also already alone it go if the foothold in the upper position.
The only snag I've found so far is that the differences between the two settings of the stage are a little too big. If the upper level is slow too high, the lower a bit too far down.
