Richell Soft Potty Seat Soft and comfortable to sit on, and the U-shape makes it easy to wipe your child's bottom because the back is open. It can be washed completely, so it's easy to clean even if it gets dirty, and it's recommended. Used for several months. There are scratches and storage marks (see photos), but there is no dirt. Nishimatsuya Potty Seat I tried to use it at my parents' house, but it didn't fit the toilet seat, so it's almost unused. This is a set of 2.
