Rare Josef Hoffmann “Fledermaus” sofa, designed circa 1900–1910 for J.&J. Kohn, Austria. A striking example of Viennese Jugendstil, this early modernist piece features a bent beechwood frame with a black finish and newly upholstered red leather seat. The sofa’s pierced backrest, curved arms, and clean geometric lines exemplify Hoffmann’s progressive design language and his contribution to the Wiener Werkstätte movement. Originally conceived for the Fledermaus cabaret in Vienna, this design remains one of Hoffmann’s most iconic and enduring works. The contrast between the bold red leather and the black frame enhances its architectural presence and timeless appeal. Dimensions: 76 cm H × 119 cm W × 55 cm D. Condition: Fair – structurally sound with visible wear, patina, and signs of age. A true collector’s piece with historic and design significance.
