Together with the painter Rainer Schenk, Christoph R. Siebrasse has developed spectacular furniture objects since the 1970s. Constructures made of square steel, marble, steel sheets and ropes as well as felt challenged traditional living concepts within the framework of the “New German Design Movement”. Designs such as the “Freethinker”, the telescoping “Russian Chair” or the “Pentagon Dodecahedron” are always at the limit of sculpture and design. With the chair “Sensilla” from 1988, Siebrasse succeeded in creating the first real cantilever chair, whose seat, suspended on four ropes, allows completely moving sitting. In addition, the artists always experimented with other materials and techniques, creating diverse, sometimes colorful wood furniture that draw a line between De Stijl and Pop Art.
