Lane Furniture for sale on 1stDibs

When the first iteration of the Lane Furniture company began to produce its now-famous Lane cedar chests in the early 20th century, the family behind the brand was unsure of how successful they’d be, so they initially didn’t bother adding their name to the offerings.

The manufacturer was off to a modest start but the family was industrious: The Lanes were made up of farmers and contractors who’d built more than 30 miles of the Virginian railroad. They owned a cotton mill and purchased thousands of acres of land in Campbell County, Virginia, where the Virginian railroad was intended to cross the main line of the Southern Railway.

The Lanes hoped to start a town in this region of the state, and by 1912, streets for the town of Altavista had been laid out and utility lines were installed. In the spring of that year, John Lane purchased a defunct box factory at a bankruptcy auction. His son, Edward Hudson Lane, was tasked with the manufacturing of the cedar “hope” chests for which the Lane family would become known, even though the company was initially incorporated as the Standard Red Cedar Chest Company.

The Standard Red Cedar Chest Company struggled in its early days but introduced an assembly system at its small factory after securing a contract with the federal government to produce ammunition boxes made of pine during World War I. The company prospered and applied mass-production methods to its cedar-chest manufacturing after the war, and, in 1922, rebranding as the Lane Company, it implemented a national advertising campaign to market its products.

Ads tied the company’s strong cedar hope chests to romance. Anchored by copy that read “The gift that starts the home,” the campaign rendered a Lane cedar chest a necessary purchase for young women to store linens, clothing and keepsakes as they prepared to marry.

Wartime production during World War II had Lane producing aircraft parts. In the 1950s, the family-owned company began to branch out into manufacturing tables, bedroom pieces and other various furnishings for the entire home. Today, the brand’s vintage mid-century furniture — which includes the PerceptionTuxedo and Acclaim collections — is highly sought after. 

Designed by Andre Bus, Lane’s Acclaim furniture collection of coffee tablesend tablesdressers and more has been compared to Drexel’s wildly popular Declaration series for its blend of traditional craftsmanship and the impeccably clean contours that are frequently associated with the best of mid-century modern design

Ads for the Acclaim line suggested that it included “probably the best-selling table in the world.” Before its offerings expanded to include items for the bedroom and dining room, Lane was primarily known for its tables and case pieces — there are side tables, coffee tables and more created by Bus in the Acclaim collection, each sporting graceful tapered legs and dovetail inlays. 

Later, during the 1960s, Lane offered handsome modular wall units created by the likes of Paul McCobb, an award-winning Massachusetts-born designer best known for his work at Directional.

The company was acquired by United Furniture Industries in 2017 and became particularly well-known among contemporary consumers for its upholstered furniture. In 2022 United abruptly closed and ceased operations at Lane.  

Vintage Lane furniture is generally characterized by relatively neutral styles, which are versatile in different kinds of interiors, as well as good quality woods and careful manufacturing. All of these attributes have made Lane one of the most recognizable names in American furniture.

A Close Look at Mid-century-modern Furniture

Organically shaped, clean-lined and elegantly simple are three terms that well describe vintage mid-century modern furniture. The style, which emerged primarily in the years following World War II, is characterized by pieces that were conceived and made in an energetic, optimistic spirit by creators who believed that good design was an essential part of good living.

CHARACTERISTICS OF MID-CENTURY MODERN FURNITURE DESIGN

MID-CENTURY MODERN FURNITURE DESIGNERS TO KNOW

ICONIC MID-CENTURY MODERN FURNITURE DESIGNS

VINTAGE MID-CENTURY MODERN FURNITURE ON 1STDIBS

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 celebrated 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.

Generations turn over, and mid-century modern remains arguably the most popular style going. 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.
