French colorful modular sofa Mah Jong by Hans Hopfer for Roche Bobois, 2000s

German designer and artist Hans Hopfer had a profound impact on furniture design that still guides the choices we make about our spaces today. Affectionately dubbed “seating landscapes,” Hopfer’s forward-looking collections of inviting, modular low-profile seating, such as the widely revered Mah Jong sofa for Roche Bobois, allowed for optimal customized arrangements in one’s living room, an innovation that reshaped relaxation at home in a significant and lasting way. 

Hopfer designed modern furniture for a manufacturer in Nuremberg during the 1960s. He met Phillippe Roche in 1970 and began his collaboration with the Roche Bobois company. When the popularity of cable television took hold in more major American cities during the 1970s, sofas and other seating became integral to contemporary living-room decor. Roche Bobois’s newly launched Les Contemporains series positioned its own sofas front and center, and it also offered plush lounge chairs designed by Mario Bellini.

Bold works from Roche Bobois during the decade included one of its most enduring and well-known pieces — the Mah Jong sectional sofa created by Hopfer in 1971. Anchored by few central elements, this modular lounge sofa can be combined or stacked, giving the buyer total freedom over its appearance and the ability to maximize comfort with its plump cushions. Inspired by a tile-based game that originated in China, the Mah Jong has been in production since its debut. It is still handmade in a workshop in Italy today. 

Composed of low seating elements and large cushions, Hopfer’s Mah Jong sofa has seen some high-profile fabric updates by Missoni, Jean Paul Gaultier and Japanese clothing designer Kenzo Takada, who worked with Roche Bobois to craft fabrics emblazoned with geometrically dynamic patterns to be used as upholstery for the firm’s iconic piece of furniture. 

Primarily a sculptor and painter by trade, Hopfer worked and lived between Buenos Aires, Nuremberg and Paris. In addition to the work he did for Roche Bobois — which included his Informel armchairs and sofas — he also created modular furniture for the Wiener Werkstatte, a collective of artists and designers born from the Vienna Secession art movement in Austria during the early 20th century.

In 1974, Roche Bobois opened its first showroom in the United States on Madison Avenue in New York City. The celebrated luxury French furniture brand is now in 50 countries with more than 200 stores.

The Roche Bobois story has origins in 1950, when entrepreneur Jacques Roche converted an old Paris theater into two contemporary furniture boutiques so that his sons could help usher stunning Bauhaus-inspired work out of the shops and into French homes nearby.

At another showroom called Au Beau Bois, also in the French capital city, the Chouchan family was simultaneously selling home furnishings. The families met later, when Philippe and François Roche convened with Patrick and Jean-Claude Chouchan at a furniture exhibition in Copenhagen in 1960 and afterward produced a catalog announcing their partnership.

Minimal and modernist Scandinavian design had gained prominence in the furniture industry by 1960, rendering designers such as Kaare Klint and Poul Henningsen marquee names — and Roche Bobois's principals had taken notice. Following a national advertising campaign in Elle magazine a year later, the Scandinavian furniture that the newly minted Roche Bobois was importing to Paris became a huge success. Early promotional material from the firm likely included the sleek modular wall units crafted in rosewood by Danish furniture maker Poul Cadovius. It didn’t take long for Roche Bobois to shift toward producing its own contemporary furniture line.

When the popularity of cable television took hold in more major American cities during the 1970s, sofas and other seating became integral to contemporary living-room decor. Roche Bobois’s newly launched Les Contemporains series positioned its own sofas front and center, and it also offered plush lounge chairs designed by Mario Bellini.

Bold works from the company during the decade included Marc Berthier’s Pop Art–colored tubular metal desks and chairs — the latter covered with braided fabric — as well as one of Roche Bobois’s most enduring and well-known pieces, the Mah Jong sectional sofa created by sculptor, painter and designer Hans Hopfer. Anchored by few central elements, this modular lounge sofa can be combined or stacked, giving the buyer total freedom over its appearance and the ability to maximize comfort.

Since its inception, Roche Bobois has worked with many internationally renowned architects and designers on its collections, among them Paola Navone and Vladimir Kagan. Even fashion designers such as Missoni and Emanuel Ungaro have made contributions to the company’s lineup.

In 2010, Roche Bobois marked its 50-year anniversary by debuting a partnership with French fashion designer Jean Paul Gaultier. A decade later, Roche Bobois teamed up with Portuguese artist Joana Vasconcelos, who designed a collection of organically shaped sofas as well as vibrant, colorful accent pillows and rugs.

Roche Bobois’s offerings over the years have included everything from mid-century modern armchairs to Art Deco case pieces to sculptural outdoor cocktail tables framed in metal wire — shop these classics now on 1stDibs.
