HOT ! \'Cosinus\' Chair by Karl Friedrich Förster for KFF

\'Cosinus\' chair designed by Karl Friedrich Förster for KFF, produced in Germany during the 1980s. The model reflects the geometrical and Memphis-influenced direction of German postmodern design, combining industrial steel construction with clear formal contrast between curved and rectilinear elements. Blackened steel frame forms two continuous arched side supports intersecting with straight horizontal and vertical members, creating a structured, architectural silhouette. The seat and semi-circular backrest are upholstered in navy leather, suspended within the metal framework to emphasize the interplay between rigid geometry and softened surfaces. Visible welds and brushed steel finishing reinforce the chair\'s industrial character. Overall well preserved and in very good vintage condition with expected signs of age. Visible welds, patina and metal processing on the frames as a part of the design, not signs of use. Structurally perfect and quality made. New dark blue faux leather upholstery. Width: 55 cm / 21.7 inches Depth: 60 cm / 23.6 inches Height: 75 cm / 29.5 inches Seat Height: 47 cm / 18.5 inches Weight: 10.5 kg / 23.1 lbs We try our best to accurately depict any imperfections on our photos.
