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.

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.
