'When I started thinking about what eventually became the JA-chair, I was wondering if it would be possible to create a well sitting chair based on a vertical circle.

Because of this challenge, it is not illogical that it has become a rocking chair.

This did entail a number of additional challenges.

What turned out to be the most complicated was to adjust the height and depth ratio of the seat in such a way that almost any height of person could sit in it properly.

In combination with the balance, this ratio ultimately determined the diameter of the chair.'
