About This Piece

Vintage Design

An iconic DS-12 modular leather sofa produced by De Sede in Switzerland during the 1970s. Upholstered in richly patinated brown neck leather, this substantial seating system embodies the essence of De Sede’s comfort-driven modernism and uncompromising Swiss craftsmanship.

The DS-12 is defined by its low, generous profile and rhythmic modular composition. Each element is softly contoured, creating a continuous visual flow while retaining a strong architectural presence. Thick, supple leather envelops the sofa, revealing natural creases and subtle tonal variations that speak to authenticity, age, and material honesty. The deep seats and wide armrests invite relaxation, while the modular structure allows the sofa to function both as a sculptural interior landscape and as highly functional seating.

Thanks to its modular construction, the DS-12 can also be configured as two separate sofas, consisting of one two-seater and one three-seater, offering flexibility without compromising the sculptural integrity of the design. A timeless and confident piece that reflects the enduring appeal of 1970s Swiss design.

Condition
In very good to almost excellent condition. The leather shows a beautiful, even patina with light signs of use consistent with age. First owner piece.
