Croomy potty training seat with handles. For toddlers. Dimensions: Diameter 36.5 cm. Dimensions of the hole in the middle of the seat: Diameter 20.5 cm, width 10.7 cm. I've also taken photos to show the dimensions, but please feel free to ask if anything is unclear. - Color: White and Green - Design: Potty training seat - Features: With handles Thank you for looking! Even my child, who was easily scared, was able to enjoy using it as if they were riding a vehicle, thanks to the handles, so I highly recommend it! It has been cleaned with soap and disinfected with alcohol. I will disinfect it again with alcohol before shipping. Price negotiations and inquiries about the seat's dimensions are welcome!
