Chokkaku in Japanese apart from meaning the right angle also means insight, intuition and instinctive intuition. I reconsturced a traditional stool. It was important for me to create a modern, artistically simple object. My additional considerations for the piece of furniture were that it should contain several parts, it should be mobile and accordingly it should have several combinations and also to be able to be folded thus being space saving. If possible, it should be made of wood ignoring other artifical materials, this is why my main aim was to find a simple intersction consequently it does not require any other fastening than gluing. I was considering the isosceles triangle as a simple geometric element and putting it in a row generated an interesting game. The final product due to its movable parts offers a variety of options for the single entity but in the case of fitting several objects together the combinations can be optional and interesting.
