Stunning vintage Kashima 1979 lounge chairs by Michel Ducaroy for Ligne Roset

The Togo sofa isn’t the only piece of furniture Michel Ducaroy designed, but it is certainly the one that he will be long remembered for. The cozy, crumpled pillow-like sofa seems never to go out of style, and its features encapsulate Ducaroy’s design philosophy of combining ergonomics and comfort with high-tech synthetic materials like foam, quilting and thermoformed plastics.

Ducaroy was born into a family of French furniture manufacturers who specialized in residential interiors as well as fittings for ocean liners. However, he elected to study sculpture at the École Nationale Supérieure des Beaux-Arts in Lyon, and this foundation would greatly influence his work and the way he thought about shape and form. Ducaroy worked at the family business and later founded his design studio in 1952.

In 1954, Ducaroy began working with Ligne Roset, the French family-run manufacturing giant known across the world for creating high-end seating. There, he was able to propel the research and development of their designs, and his work quickly became integral to the company’s identity.

Ducaroy’s innovations with thermoformed plastics and biomorphic forms can be seen in early designs for Ligne Roset in the ’60s and ’70s, like the cozy, modular Adria chair and low-sitting Kashima sofa. He designed the Togo furniture line in 1973 using an innovative all-foam seating structure that was covered with polyester; decades later the Togo sofa remains a Ligne Roset best seller.

The low rise and unique curve of any Ducaroy sofa make it instantly recognizable, and the distinctly Pop art–inspired, organic forms that the celebrated designer created from synthetic materials like polyester and foam made a powerful statement at their inception, as they continue to do now.
