This highly desirable DS31 black leather three-seat sofa, is built by De Sede, Switzerland in the late 1960s. The sofa guarantees a great seating comfort and sits on nice designed polished chrome-plated legs. The DS-31 combines design, craftsmanship, and leather expertise to create a timelessly beautiful upholstered model. The passion for craftsmanship is reflected in the strap stitching, which is artfully applied by hand and with the utmost care to the upholstery edges and armrests. This iconic model is brought to you in a very well preserved vintage condition. 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
