Iconic DS5 sideboard from the “I Maestri” collection designed by Charles Rennie Mackintosh and produced by Cassina in Italy during the 1990s. Originally conceived in 1918, this piece reflects Mackintosh’s unique synthesis of Arts & Crafts discipline, early Modernist geometry, and subtle Art Nouveau detailing. The design is defined by its strong architectural presence, featuring a black-stained ash structure with visible wood grain and an upper section enriched with decorative leaded glass panels arranged in a geometric mosaic composition. The sideboard combines visual impact with practical storage, offering multiple doors and internal compartments, making it suitable for both residential and contract interiors. Produced by Cassina as part of the prestigious “I Maestri” series, this edition faithfully reinterprets Mackintosh’s original design with high-quality Italian manufacturing standards. A sculptural and highly recognisable piece that bridges historical design heritage with contemporary interior aesthetics.
