Swivel chair

Weightless sitting. Without effort, without tension, without fatigue. Before there was the Sedus swing up it seemed an unattainable utopia. But now you can experience a completely new quality of sitting. Thanks to scientifically sound, innovative technologies swing up allows exactly the natural sequence of movements that a person needs in order to feel good and stay healthy, to unfold and maintain their full potential. Sedus swing up – so perfect, as if you were floating.

Life is movement. Better sitting is too

Sedus swing up was developed in scientific cooperation with the TU Munich. To rethink sitting in the office you need to explore the complex interactions of people’s bodies, minds and psyches. The result in a nutshell: freedom of movement is the key. Just as you can see in children, who still let their natural instinct to move run free. The functionality of an office chair must provide scope for the urge to move that evolution has deeply rooted in humans.



Excellent technology that understands the body

A person who moves not only feels more comfortable, they can also use their potential for performance better. Livelier sitting also means livelier thinking, working and communicating. What is essential: movement must be able to happen, controlled autonomously by the body. Thanks to the Dorsokinetic backrest, its seat surface  is mounted so it can move in all directions, and the powerful return springs. swing up actively andrespond to every movement of the body. It offers well-measured free spaces and completely adapts to the individual activity profile of its user.





Natural freedom of movement

A completely new seating concept. The body knows what it needs, Sedus swing up provides it.
The combination of proven Sedus technologies and the patented Similar-Swing mechanism allows frequent changes of posture with uniquely smooth sequences of movement, while optimally absorbing the particularly important lateral hip and pelvic movements and promoting dynamic sitting.



Sustainable production

We purchase around two thirds of the steel, aluminium and wood which we require to produce our products in Germany and almost all the rest from Europe, this helps us to avoid long delivery routes whilst, at the same time, boosting the local economy. We use materials which have been tested and assessed with respect to potentially adverse effects on human health and the environment.
