open mind

Swivel chair

Vision. Transparency. Clear design. Concentrating on the essential, open mind motivates with exceptional freedom of movement. Lean back and relax. Correct posture is ensured by this aesthetically pleasing swivel chair. With its innovative backrest frame and highly flexible membrane covering in a refreshing range of colours. Unconstrained by time or place. Open to new tasks.

Design: Mathias Seiler (Sedus Design Team)

The professional solution for relaxed and efficient working

Greater simplicity of design is hardly possible. Just like the open up chair, open mind also offers extensive manoeuvrability. This allows a flexible sitting or lying posture, thanks to the “Similar” mechanism, with its large opening angle which moves in  synchrony with the body. The integrated backrest support with highly flexible membrane ensures ideal sitting comfort – in accordance with the rules of bionics. Additional features such as seat depth and tilt adjustment unite the ambitious design with the outstanding ergonomics.
