Product details
Cosinus by Karl Friedrich Förster for KFF, Germany, 1980s. A chair in the language of postmodernism. Geometric, with Memphis influences. The blackened steel frame traces two continuous arcs, framed by clear transverse and longitudinal elements. This creates an architectural silhouette. The seat and semicircular backrest are suspended within the frame. Newly upholstered in dark blue faux leather. Visible welds and brush marks are part of the design. Industrial, precise, serene. Overall very well preserved with an age-related patina. A structurally sound design that balances structure and comfort. Solidly crafted. Proportionally balanced.
