De Sede sofa

This rare modular sofa, model DS-11, produced by De Sede in Switzerland, exemplifies the brand’s reputation for luxury, craftsmanship, and innovative design. Originally conceived in the 1970s, the DS-11 reflects the era’s embrace of generous proportions and tactile materials, while its modular construction lends it lasting functional relevance.

Upholstered in its original cognac brown leather, the sofa features a richly textured surface with a warm, earthy hue. The leather has developed a well-preserved patina over time, characterized by natural creases and tonal variation that enhance the visual depth and vintage character of the piece. These surface qualities underscore the authenticity and history of the sofa, making it both visually striking and inviting.

The modular design consists of multiple segments joined to form a long, continuous seating area—measuring 360 cm in length, 85 cm in depth, 63 cm in overall height, and 36 cm in seat height (141.7 x 33.5 x 24.8 x 14.2 inches). This format allows for reconfiguration, adapting to a variety of room layouts, whether in a linear alignment or more sculptural, angular compositions.

The form is defined by its deep, horizontal tufting—a signature detail of the DS-11 model—that spans the seats and backs in uniform bands. This tufting adds visual rhythm and depth while enhancing the comfort of the thick, supportive cushions. The design is low-slung and softly contoured, creating an inviting and lounge-like atmosphere ideal for relaxed living environments.

The leather upholstery is paired with high-quality internal construction, typical of De Sede’s standards. The stitching is precise and robust, and the modular elements connect securely, allowing the sofa to function as a cohesive and stable unit. Despite its age, the build quality ensures continued comfort and durability.

Condition is very good vintage. The leather shows expected signs of use, including minor scuffs and wear in places, which contribute to the piece’s authenticity. All modules are structurally sound, and the upholstery remains supple and intact.

De Sede, founded in Klingnau, Switzerland, built its international reputation on hand-stitched leather seating of exceptional quality. The DS-11 stands among the company’s iconic models, embodying both a mid-century modern sensibility and a timeless appeal. This particular sofa is not only a highly functional seating solution but also a sculptural centerpiece that speaks to the enduring legacy of European modernist design.
