Made from 100% sheet aluminium, AS-24 reflects the design principles I set for myself. I challenged myself to create a design without introducing any other materials, which meant that hinges, locking mechanisms, and all other components had to be made entirely from sheet aluminium.

This led to a much deeper understanding of the material — what it can do, and what it cannot. It has been a process full of trial and error, but I believe that kind of experimentation is the best way to learn, at least for me.

The mechanisms of the stool are quite simple. For example, I used the aluminium’s natural spring-back to create a locking mechanism that allows the two sides to slide easily together while preventing them from coming apart. It took time and many iterations to make it work, but I’m happy with the result.

One of the defining features is the hinge, shaped from a cutout in the seat that bends around the side. This element has been part of the design almost since the beginning. I remember talking to Metal-Henning, the craftsman who helped bring the design to life. He looked at the hinge and said: “Emil, what is this? It can’t be done — we’ll have to bend it by hand.” And he was right. To attach the top to the sides, we had to bend it by hand — a process that gives each stool a personal touch.
