This “DS-600” sofa, designed by Ueli Berger, Eleonore Peduzzi Riva, Heinz Ulrich, and Klaus Vogt for De Sede in the early 1970s, is one of the most celebrated icons of 20th century furniture design. The sofa's fluid, serpentine form challenged traditional ideas of the living room by transforming seating into an adaptable architectural element. More than fifty years after its introduction, the “DS-600” remains a defining example of innovative Swiss craftsmanship and modular design.
As this sofa shows - functionality was not perfected at the expense of aesthetic appeal and quality. This outstanding modular piece has a creative design that allows it to be used in a multitude of ways. The ingenious design can bend into sweeping curves, circles, or custom configurations. Its exceptional comfort is matched by remarkable flexibility, making each installation unique to its environment. The sofa is upholstered in leather with a beautiful patina. The use of this material not only enhances the visual appeal but also ensures a comfortable and supportive seating experience for the whole body. The overall design speaks to the zeitgeist of the 1970s, a period characterised by a spirit of experimentation and a departure from traditional norms. This piece embodies the essence of modern design, marked by its commitment to functionality, and a bold experimentation.
Produced by the renowned Swiss manufacturer De Sede, the “DS-600” exemplifies the company's commitment to exceptional leatherwork and enduring quality. Often referred to as the "Snake" or "Non-Stop" sofa, it has become a sought-after collectible and a permanent fixture in museums, and design collections around the world. Combining playful experimentation with impeccable craftsmanship, the “DS-600” continues to stand as a timeless statement of functional sculpture and enduring modern design.

Illum Wikkelsø was a recognisable figure of Danish seating design in the post-war decades, known for creating furniture that combined sculptural silhouettes with a strong emphasis on comfort. Working throughout the 1950s and 1960s with manufacturers such as Søren Willadsen, Wikkelsø developed lounge chairs and sofas that softened the stricter geometry of earlier modernism through curved lines. His designs often relied on exposed wood, generous upholstery, and carefully balanced proportions, allowing seating to feel visually substantial without becoming heavy.
Model “110” reflects this approach through its dramatic winged silhouette and restrained material palette. The chair is upholstered in black leather that wraps continuously around the high back, seat, and armrests, emphasizing the sculptural quality of the form. The backrest rises upward into pronounced side panels that connect the wings to the armrests. The sides curve gently forward, creating a protective and enveloping shape around the sitter. These extended sides visually frame the head and shoulders. The leather surface contributes to the overall character of the piece: its subtle texture catches light differently across the curved sections, giving depth to the large upholstered planes. In contrast to the dark upholstery, the chair rests on a solid wooden base with angled legs that introduce warmth and visual lightness. The exposed wood creates a clear separation between the upholstered body and the floor.
The balance between softness and structure is central to the success of this design. The chair carries the commanding presence associated with high-back lounge seating, yet the flowing transitions between its elements prevent it from feeling rigid. Wikkelsø’s ability to merge comfort with sculptural clarity is especially evident here, making the model equally compelling as functional seating and as a statement piece within an interior.
