This cheerful pee pot has a removable inner pot. When your child is ready for the step to the large toilet, you can convert the pee potty into a step and a separate toilet seat that you place on the existing toilet seat. The toilet seat is made of a soft foam and ergonomically shaped for optimal support and comfort. Because these glasses are not made of hard, cold plastic but of a friendly soft foam, it does not feel cold and will certainly be a favorite with your child. The step has an anti-slip base so safe for those little ones to stand on.
