Modern Circular Sectional Colorful Sofa by Vladimir Kagan for Roche Bobois

The pioneers of modern furniture design in America in the mid-20th century all had their moments of flamboyance: Charles and Ray Eames produced the startling, biomorphic La Chaise; George Nelson’s firm created the Marshmallow sofa; Edward Wormley had his decadent Listen to Me chaise. But no designer of the day steadily offered works with more verve and dynamism than Vladimir Kagan. While others, it seems, designed with suburban households in mind, Kagan aimed to suit the tastes of young, sophisticated city-dwellers. With signature designs that feature sleekly curved frames and others that have dramatic out-thrust legs, Kagan made furniture sexy.

Kagan’s father was a Russian master cabinetmaker who took his family first to Germany (where Vladimir was born) and then to New York in 1938. After studying architecture at Columbia University, Kagan opened a design firm at age 22 and immediately made a splash with his long, low and sinuous Serpentine sofa. Furniture lines such as the Tri-symmetric group of glass-topped, three-legged tables and the vivacious Contours chairs soon followed.

Kagan’s choices of form and materials evolved through subsequent decades, embracing lucite, aluminum and burl-wood veneers. By the late 1960s, Kagan was designing austere, asymmetrical cabinets and his Omnibus group of modular sofas and chairs. For all his aesthetic élan, Kagan said that throughout his career, his touchstone was comfort. “A lot of modern furniture was not comfortable. And so comfort is: form follows function. The function was to make it comfortable,” he once commented. “I created what I called vessels for the human body.”

A diverse group of bodies have made themselves at home with Kagan designs. Among the famous names who commissioned and collected his designs are Marilyn Monroe, Gary Cooper, Andy Warhol, David Lynch, Angelina Jolie and Brad Pitt, and firms such as Gucci and Giorgio Armani. His work is in numerous museum collections, including those of the Victoria & Albert and the Metropolitan Museum of Art.

Because of its idiosyncrasy, Kagan’s work did not lend itself to mass-production. Kagan never signed on with any of the major furniture-making corporations, and examples of his designs are relatively rare. As you will see from the offerings on 1stDibs, even decades after their conception, Kagan pieces still command the eye, with their freshness, energy, sensuality and wit.

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.
