De Sede DS-125 two-seat sofa

Two-seat sofa from the iconic DS-125 collection, designed by German architect Gerd Lange for De Sede, Switzerland in 1978. This sculptural model is known for its fluid, monolithic shape, distinctive zippered seams, and bold armrest curves — a hallmark of late 1970s Swiss modernism. This example is upholstered in its original thick buffalo leather, a material prized for its durability, strength, and ability to develop rich patina over time. The leather on this piece clearly shows signs of age and use, including visible staining, discoloration, and wear throughout. These marks of time give the sofa a raw, authentic vintage look that reflects its 1970s origins. Despite its lived-in condition, the structure remains solid and the seating comfort is intact, making this perfect for collectors who appreciate honest vintage pieces in original condition. A collectible piece with strong architectural presence!
