Thonet Armchair, Model No. 511 — Black Lacquered Wood and Red Upholstery This elegant armchair, Model No. 511, was manufactured by the iconic Viennese firm Thonet, a name synonymous with 19th and early 20th-century innovation in bentwood furniture. The piece features a sculptural silhouette crafted from black lacquered wood, showcasing Thonet’s pioneering bentwood techniques. The refined frame is paired with vibrant red upholstery, creating a bold contrast that enhances its visual presence. Measuring 101.5 cm in height, 54 cm in width, and 60 cm in depth, the chair balances comfort with architectural elegance. Its slender proportions and dynamic curves reflect the enduring influence of Jugendstil design on Thonet’s work.
