Chair Model 31 also called Handy chair by Kai Kristiansen is from 1957; it was the first one Schou Andersen made and it was sold through IKEA, his biggest client at the time. That is why some of the designs have been sold both by IKEA and by furniture retailers. When IKEA started making a serious move into the furniture market it wasn't popular selling via both channels anymore, and Schou Andersen stopped the collaboration with IKEA.
The chair itself is amended so that the line of the arm towards the seats back forms an arch. This chair guarantees a very comfortable seating experience.
The chair is currently produced by Miyazaki Chair Factory in Japan.
