Eero Aarnio achieved his breakthrough as a designer at the international Furniture Fair in 1966 in Cologne, as the Ball Chair, sometimes called the Globe Chair, attracted the attention of experts.
In 1966 the Ball Chair was presented at the international furniture fair in Cologne.In its brochure, the Vitra Design Museum described the Designer Chair as a work between furniture design and architecture, a view which is also reflected in Eero Aarnio’s dictum that the chair is "a space within a space". Since that time the design of the Ball Chair has lost none of its topicality - on the contrary, it has influenced, inspired and co-created many generations.
The secret of its success is the simplicity of the geometric shape of the ball. In nature, it stands for stability and balance, perfection and beauty, but also for power, energy and infinite complexity in mathematics.
Finally, in philosophy, it represents the human striving after knowledge and accomplishment. The Italian painter Giotto is said to have been able to draw a perfect circle freehand. Most certainly, watching Eero Aarnio design his master pieces would give him real pleasure.
To test the dimensions of the Chair, he painted a circle in the later original size of the Chair and tried its movements, which is how he later arrived at the correct size of the ball.
It should be comfortable to get in and out; however, the finished ball Chair should fit through a door - a balance that was achieved by constant trial and error. Maybe Giotto is not the only one who would enjoy the sight of the designer at work... Thus, the path to the Ball Chair by Adelta, one of the turning points in twentieth century furniture design, was as unconventional as the result, which continues to impress individualists around the world even forty years after its premiere.
