What is Erwan Bouroullec holding here in his hands, some ungodly monitor stand?
Nope, it's a chair frame.



This Arba chair has a wonderful gesture that somehow evokes MCM while looking unabashedly modern. The geometry of the lone steel support has been so optimized and minimized that the chair almost—almost—seems like it's missing something.




Steel and geometry are good partners because steel is stiff and elastic at the same time. ARBA is a structure reduced to the maximum to make the construction lightweight and simple while also allowing a certain flex, which is key to enabling different bodies of users to interact with the chair. To reinforce this capability, we also used some silent blocks to bring another grade of movement to the chair. So ARBA is made of few lines, shells and points, carefully balanced to create a proper behavior for the lounge.





The chair is in production by Danish manufacturer Raawii.

What I'm curious about is how much weight this chair can bear.
It's strange that the seat support has a gusset, but the back doesn't. The flat bar "frame" will deform quickly. I'd have thought any deformation of a backrest is unacceptable because it will alter its geometry.
The gusset for the seat is necessary because of how the seat plate mounts perpendicular to the frame. That would be too much leverage to leave unsupported. The plate for the backrest is parallel to the frame, though. And the frame looks like it's at least 8 gauge steel, which is like...4.2mm. That's pretty bomber. Even more so if it's some kind of high carbon steel.
