After we had long sought and tried some unsuitable specimens (which was not helpful to our 3 year old son closer to the potty usage), we got to Baby Bjorn Potty Chair paid. Finally the right thing! The Potty Chair is big enough for larger pot users to be comfortable and completely unproblematic to benefit by the generous oval shape his pot use it is for guys here all fits purely without jamming and preventing splashing out! The use is therefore even easier to remove and clean. I highly recommend the pot!
