Following a maxim of simplicity, some 30 years ago designers Klaus Franck and Werner Sauer created the FS-Line which became a classic example of dynamic seating. Modus was the two designers’ translation of the principle to the aesthetics of the 21st century. • The flexible, fork-shaped backrest made of unbreakable, high- efficiency plastic is covered with an exchangeable, breathable high-tech fabric. Without any upholstery, the backrest adapts to the shape, posture and movement of the person sitting on it. • Withitssoftandroundedfrontedge,thebreathable,uphol- stered seat allows the body to relax and prevents the pelvis from tilting. Because they are easy to exchange, the covers and up- holstery guarantee the chair’s useful life is virtually unlimited. • Theparticularlycomfortableandextremelycompactautomatic synchro-adjustment with torsion springs ensures the seat and backrest are lowered in perfect sync with your body. The stylish swivel arms, made of high-quality die-cast aluminium, are functional and design elements in equal measure. It is no surprise that Modus has become an international bench- mark for a new generation of office chairs. Much talked-about, but still one of a kind, it has remained in a class of its own till to- day: dynamic seating at its best.
