De Sede Terrazza Sofa Cognac Leather Ubald Klug Ueli Berger 1972 Mid Century

Furniture designer Ueli Berger and his wife, Susi Berger-Wyss, collaboratively designed furniture for over 40 years, establishing themselves as influential mid-century modern designers. The Swiss duo produced geometric designs with playful artistry that reflected their longstanding credo: “only a new idea justifies a new piece of furniture.”

In the 1950s, Ueli Berger apprenticed as a painter before attending a trade school and school of arts and crafts. In the early 1960s, he worked with Swiss interior designer Hans Eichenberger. After he married Susi, the couple partnered on furniture design for Swiss manufacturers Victoria-Werke, de Sede and Röthlisberger. In 1965, Berger became head of design and development at Troesch in Bern. By 1971, he was self-employed with his own studio.

Among the couple’s best-known designs is the de Sede lounge chair. Its form is related to the modular seating Berger completed with designers Eleonore Peduzzi Riva, Heinz Ulrich and Klaus Vogt. While the modular chairs and sectional “snake” sofas offer a high level of customization, the lounge chair — complete with a tall back and X-shaped frame made from dark lacquered wood — is an innovation marvel. Upholstered in cognac leather, Berger’s seating feels as sexy, comfortable and radical as it did in its heyday.

The pair received the Swiss Grand Award for Design and exhibited work in museums around the world, including the Museum of Modern Art in New York and Switzerland’s leading design and visual communication museum, the Museum für Gestaltung Zürich. Their Cloud Lamp, or Wolkenlampe, was featured in Modern Magazine and designs for Röthlisberger like the Kungfu Regal shelving and Robot Kommode continue to attract the attention of collectors and modern decorators.

A de Sede piece lends a strong personality to the room it occupies. One of the world’s most respected furniture design houses, de Sede’s quality Swiss craftsmanship has its foundation in a long history of making expertly designed saddles. Founded in 1965 to build on a successful family-run saddler’s workshop in Klingnau, Switzerland, de Sede now is a leading manufacturer of leather goods and furniture, including sofas, chairs and beds.

At the core of de Sede’s philosophy is a reverence for the complexity and beauty of handcrafted furniture in an age when mass-produced objects are the norm. Over the years, the atelier has built a name for itself in its modular furniture pieces, which are made using the highest quality leather upholstery. The sleek, elegant pieces incorporate functionality with beauty. Amongst their best-selling designs is the DS-600 introduced in 1972. Also known as the Non Stop sofa, it is a sensually curved, snaking modular sofa whose individual pieces can be zipped together to create multiple variations and arcs.

De Sede has collaborated with some of the world's finest design minds, enhancing the prestige and individuality of their products. Designers like Santiago Calatrava, Antonella Scarpitta, Stephan Hürlemann, Gordon Guillaumier and Philippe Malouin have all created pieces with the atelier. Ubald Klug’s 1974 DS-1025, also known as the Terrazza sofa, is an enduring favorite with its cascading levels of leather. In 2017, de Sede expanded its product line to include high-quality leather handbags, which are as thoughtfully designed and beautifully crafted as its furniture. De Sede AG is now part of the Volare Group AG and continues to handcraft its fine furniture and other goods from its factory in Klingnau.
