In the kitchen, at the sink, at kindergarten or at a ergotherapy session: kids love to stand on Carl. Andreas Haase invented and named this learning tower for and after his son Carl so that he could take part in everything that happened in their kitchen. He saw what kids needed: a high seat is too restrictive for a child, where as a secure, the learning tower allows kids from one to seven years old to experience things on raised surfaces firsthand. A clever, participatory piece of furniture.
