Adjustable closestool / closestool

Adjustable closestool

Adjustable closestool encourages children to use closestool by themselves, and so the parents’ burden is released.
When children sit on the common closestool, their relatively short legs is not easy to touch the ground. So this abnormal sitting posture makes children uncomfortable. The Adjustable Closestool solves the problem well.
