Modus. The aesthetics of sitting.

Sitting has become our second nature. We take sitting for granted, wher-ever and whenever we wish: at home or at work, on the train, plane orinthe car, in front of the television, while eating or at the theatre. Expertsestimate that we spend some 80,000 hours sitting on an office chair in ourworking life, increasingly accompanied by numerous occupational conditions which are virtually all connected with lack of exercise.The design of an office chair is also an expression of corporate identity andhow individuals are rated in their employment environment. It is thereforehardly surprising that the development of office chairs manufacturer has always been one of the greatest challenges for designers and home architects. They are faced with having to correlate ergonomic requirements, the expressive character of the design and also aspects relating to physical posture.The two designers Klaus Franck and Werner Sauer had designed a classicchair for dynamic sitting under the Wilkhahn motto of “sitting without a driving licence” some 25 years ago: the FS-Line still marks a pure symbiosis of the intuitive function of support and movement, ingeniously simple construction and design with lasting appeal.With the development of the Modus office chair range, the two designerstransferred this principle to the technical scope and aesthetics of the 21st century. The combination of minimal material input, maximum transparen- cy and optimal access for support and movement have made Modus aninternational model of excellence for a new generation of office chairs.Often imitated but still unrivalled, Modus is a class of its own: the perfec- tion of dynamic sitting.
