There are many chairs in the world. Chairs pursuing the beauty of appearance and chairs that are extremely comfortable to sit on. However, this chair is a bit different from those chairs. This chair is completed by making a single plane into a solid. In other words, it is a chair with a new way of making it. Cut a single cut into a planar shape like a missing semicircle, and cut out a pentagon. The pentagon becomes the seating surface, and when the remaining cut circle is wrapped around it, it becomes the foundation. If you made chairs with such a mechanism, it inevitably became this shape. I chose this light chair born from the plane as a "scarf chair".
