Two-seater sofa model DS-47 by De Sede, produced in Switzerland during the 1970s. Upholstered in heavy dark brown neck leather of approximately 0.5 cm thick, featuring a rich natural texture and beautifully aged patina. The design is defined by its broad, flowing lines, generous armrests and deep, relaxed seating comfort. The extendable seat provides additional lounging space. A timeless and substantial piece with attractive signs of age and use consistent with time. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
