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.
