Really useful not for each toilet, since the structure allows only 3 alternative heights Our toilet seat is too wide or too high up, so that we must have are underneath the bath mat, otherwise the swing "feet" about 5 cm in the air for our daughter loves the comfortable seat and the ducks it. Even ascend and turn on the stage but has not yet been possible alone with their 1 1/4 year. price is unbeatable, have been like nothing found
