For the manufacturer materia (www.materia.se), part of the Swedish company Kinnarps, Alexander Rehn Designstudio designed the stool Rocca.
The Rocca stool has a playful design that helps the body to keep active. The steel tubing gives the stool a minimalistic appearance, something that also makes it unique.

I wanted to design a fun product that would encourage the body to move, a way of keeping active. It started with a few experiments in plywood, but quite soon I decided to use steel tubing instead, because it gave a more minimalistic look. It was also more suitable as I wanted to create something with a clean expression. At the same time, I wanted it to be easy to carry around for informal meetings.
The ring encourages movement and the seat lets you sit comfortably. Together they form a unit that interacts.
