The history of dynamic sitting
150 years is a long time. This is a time in which Sedus developed from producing the first steam-bent wooden chair to complete office furnishings . The company helped shape a number of milestones and contributed to the history of dynamic sitting and trends in the seating furniture sector – not least dynamic seating. Christoph Stoll, from the third generation of the founding family and Managing Director from 1958 to 1995, was a pioneer and innovator in the industry.
In 1958, after the business separation from his brother, Christof Stoll decided to register the brand name Sedus for his company. The new brand developed positively and progressively from the start. With his entrepreneurial skills, Christof Stoll proved that successful management, innovative strength, and ecological principles were not mutually exclusive. He also allowed the inventive spirit of the family to continue to thrive in a contemporary sphere. After the gradual move from Waldshut to Dogern – where there is significantly more space – the next growth steps were not far behind. To this end, in 1970 he set up his own development and testing department in the vacant premises at the Waldshut site.
Christof Stoll was fascinated by the principle of “dynamic sitting”. He always set new impulses that support physiological movement processes while sitting as optimally as possible. As a visionary, he combined the cybernetics school of thought, seeking the interplay of forces, with the teachings of Anthroposophy. And the results were not long in coming.
Dynamic sitting thanks to new technology
In 1973, Sedus developed new swivel chair technologies that still play a decisive role in high-quality desk chairs worldwide today. This includes the development of the anatomic seat and the permanent contact backrest, which supports the back even when the sitting position changes. This avoids particular strain on the spine. The “Similar” mechanism (also synchronous mechanism) controls the inclination of the backrest with the seat, in sync with the body. When leaning back, the angle opens in sync with the movement of the upper body and thighs, so that the joints are moved, the body is stretched and blood circulation is also facilitated. A big leap in the development of modern office chairs and a big step for the principle of “dynamic sitting” which concludes the early history of dynamic sitting.
