Florence Knoll Lounge Chairs Model 51

Architect, furniture designer, interior designer, entrepreneur — Florence Knoll had a subtle but profound influence on the course of mid-century American modernism. Dedicated to functionality and organization, and never flamboyant, Knoll shaped the ethos of the postwar business world with her skillfully realized office plans and polished, efficient designs for sofas, credenzas, desks and other furnishings.

Knoll had perhaps the most thorough design education of any of her peers. Florence Schust was orphaned at age 12, and her guardian sent her to Kingswood, a girl’s boarding school that is part of the Cranbrook Educational Community in suburban Detroit. Her interest in design brought her to the attention of Eliel Saarinen, the Finnish architect and head of the Cranbrook Academy of Art. Saarinen and his wife took the talented child under their wing, and she became close to their son, the future architect Eero Saarinen. While a student at the academy, Florence befriended artist-designer Harry Bertoia and Charles and Ray Eames. Later, she studied under three of the Bauhaus masters who emigrated to the United States. She worked as an apprentice in the Boston architectural offices of Walter Gropius and Marcel Breuer; Ludwig Mies van der Rohe taught her at the Illinois Institute of Technology.

In 1941, she met Hans Knoll, whose eponymous furniture company was just getting off the ground. They married in 1946, and her design sense and his business skills soon made Knoll Inc. a leading firm in its field. Florence signed up the younger Saarinen as a designer, and would develop pieces by Bertoia, Mies and the artist Isamu Noguchi.

Florence Knoll's main work came as head of the Knoll Planning Group, designing custom office interiors for clients such as IBM and CBS. The furniture she created for these spaces reflects her Bauhaus training: the pieces are pure functional design, exactingly built; their only ornament from the materials, such as wood and marble. Her innovations — the oval conference table, for example, conceived as a way to ensure clear sightlines among all seated at a meeting — were always in the service of practicality.

Since her retirement in 1965, Knoll received the National Medal of Arts, among other awards; in 2004 the Philadelphia Museum of Art mounted the exhibition “Florence Knoll: Defining Modern” — well deserved accolades for a strong, successful design and business pioneer. As demonstrated on these pages, the simplicity of Knoll’s furniture is her work’s great virtue: they fit into any interior design scheme.

The mid-century modern era saw leagues of postwar American architects and designers animated by new ideas and new technology. The lean, functionalist International-style architecture of Le Corbusier and Bauhaus eminences Ludwig Mies van der Rohe and Walter Gropius had been promoted in the United States during the 1930s by Philip Johnson and others. New building techniques, such as “post-and-beam” construction, allowed the International-style schemes to be realized on a small scale in open-plan houses with long walls of glass.

Materials developed for wartime use became available for domestic goods and were incorporated into mid-century modern furniture designs. Charles and Ray Eames and Eero Saarinen, who had experimented extensively with molded plywood, eagerly embraced fiberglass for pieces such as the La Chaise and the Womb chair, respectively. 

Architect, writer and designer George Nelson created with his team shades for the Bubble lamp using a new translucent polymer skin and, as design director at Herman Miller, recruited the Eameses, Alexander Girard and others for projects at the legendary Michigan furniture manufacturer. 

Harry Bertoia and Isamu Noguchi devised chairs and tables built of wire mesh and wire struts. Materials were repurposed too: The Danish-born designer Jens Risom created a line of chairs using surplus parachute straps for webbed seats and backrests.

The Risom lounge chair was among the first pieces of furniture commissioned and produced by legendary manufacturer Knoll, a chief influencer in the rise of modern design in the United States, thanks to the work of Florence Knoll, the pioneering architect and designer who made the firm a leader in its field. The seating that Knoll created for office spaces — as well as pieces designed by Florence initially for commercial clients — soon became desirable for the home.

As the demand for casual, uncluttered furnishings grew, more mid-century furniture designers caught the spirit.

Classically oriented creators such as Edward Wormley, house designer for Dunbar Inc., offered such pieces as the sinuous Listen to Me chaise; the British expatriate T.H. Robsjohn-Gibbings switched gears, creating items such as the tiered, biomorphic Mesa table. There were Young Turks such as Paul McCobb, who designed holistic groups of sleek, blond wood furniture, and Milo Baughman, who espoused a West Coast aesthetic in minimalist teak dining tables and lushly upholstered chairs and sofas with angular steel frames.

As the collection of vintage mid-century modern chairs, dressers, coffee tables and other furniture for the living room, dining room, bedroom and elsewhere on 1stDibs demonstrates, this period saw one of the most delightful and dramatic flowerings of creativity in design history.

While this specific seating is known to all for its comfort and familiar form, the history of how your favorite antique or vintage lounge chair came to be is slightly more ambiguous.

Although there are rare armchairs dating back as far as the 17th century, some believe that the origins of the first official “lounge chair” are tied to Hungarian modernist designer-architect Marcel Breuer. Sure, Breuer wasn’t exactly reinventing the wheel when he introduced the Wassily lounge chair in 1925, but his seat was indeed revolutionary for its integration of bent tubular steel.

Officially, a lounge chair is simply defined as a “comfortable armchair,” which allows for the shape and material of the furnishings to be extremely diverse. Whether or not chaise longues make the cut for this category is a matter of frequent debate.

The Eames lounge chair, on the other hand, has come to define somewhat of a universal perception of what a lounge chair can be. Introduced in 1956, the Eames lounger (and its partner in cozy, the ottoman) quickly became staples in television shows, prestigious office buildings and sumptuous living rooms. Venerable American mid-century modern designers Charles and Ray Eames intended for it to be the peak of luxury, which they knew meant taking furniture to the next level of style and comfort. Their chair inspired many modern interpretations of the lounge — as well as numerous copies.

On 1stDibs, find a broad range of unique lounge chairs that includes everything from antique Victorian-era seating to vintage mid-century modern lounge chairs by craftspersons such as Hans Wegner to contemporary choices from today’s innovative designers.
