Over 20 years ago two young designers at Wilkhahn recognized that sitting still cannot be healthy. Both of them wanted to give adults their natural mobility back. Following intensive studies, they developed the FS-Line, a chair that revolutionized the office furniture industry. Since then, we have produced 40 variations of this chair. Millions of these have been sold worldwide; they have been inundated with awards and have often been imitated - but not very successfully. The principle is quite simple: the highly flexible seat shell adjusts automatically to any change in posture. The technical term for this is: "automatic synchro- adjustment". We call it "Sitting without a driving licence."
Swivel chairs with automatic synchro-adjustment: the seat and the backrest tilt adjust automatically to the seating position of the user. When the user leans back, the backrest tension increases accordingly. Infinitely variable adjustment of tension. Forward work position lockable by pressing the lever. Infinitely variable adjustment of seat height by means of an encapsulated gas lift.
Various types of upholstery, wide selection of upholstery materials for leather or fabric cover. Cantilever chairs and visitor's chairs are available to match all series of swivel chair models (with and without armrests).
5-star base
In die-cast aluminium, chromium-plated, polished or coated. Double swivel castors, with load-dependent braking, in black polyamide or polyurethane (for hard floors).
Seat shell
In high resilient polypropylene with a flexible middle section, through-dyed in the colours natural white, platinum, asphalt and black to render marks from use hardly visible. Armrests in the same material. The upholstery comprises covered, breathing - and exchangeable - one-piece moulded foam; on some models with additional wool fleece overlay and stitched border
