What was the inspiration behind the Balance Chair?

This is a video of a conversation between the inventor, Hans Christian Menscholl, and Balance Lab's president, Sakamoto.
We asked the inventor of the Balance Chair some common questions.

In this video, we ask the question, "How did you come up with the idea for the Balance Chair?"
The balance chair is different in shape and sitting style from ordinary chairs, so we asked where the idea for the balance chair came from and about the origins of the idea.
