Marcel Breuer designed the S 64 in 1928, during his time in Berlin. The SERIOUS reinterpretation of the S 64 features a seat and backrest in either leather upholstery (available in four different colors) or in the dark-colored canework version DARK MELANGE. The chair's wooden frames and armrests are done in a matching high-gloss lacquer.
