Acknowledged for his revolutionary designs in the Modern creation movement, the Swiss-French architect Le Corbusier work several trial designs for furniture. These experimental styles, completed in partnership with Pierre Jeanneret and Charlotte Perriand in 1928, integrated the International Style frequently linked with modern furniture and were with the earliest paradigm of modern furniture design. One such modern furnishing by Le Corbusier is the LC3 Sofa Le Corbusier.

Though Le Corbusier once declared that sofas are for bourgeois, it is quite an astonish that one of his most famous creations is the LC3 Sofa Le Corbusier. Together of the LC3 furniture group, the Le Corbusier No. 3 or LC3 Sofa is a two-seater sofa composed of an exterior steel frame and floppy black cushions. The LC3 Sofa is influened on Le Corbusier's earlier Grand Comfort armchair design, and was among the chosen pieces exhibit at the prominent 1929 Autumn Salon art exposition in Paris.

In accordance with the simple element of the International Style, the LC3 Sofa Le Corbusier is essentially comprised of two parts: the external tubular steel frame and loose black cushions. The sofa's exterior frame was ground-breaking for its time, as customary sofas done during that period were positioned on the inside rather than in the exterior. The cushions, in the temporarily, were created with polyurethane, polyester or natural down fiber and sheltered with either black fabric or leather.

The LC3 Sofa Le Corbusier was first created in the 1930s by the Thonet furniture company Embru. In 1964, the Italian designer furniture company Cassina gained the privileges from Le Corbusier to reproduce his works. Now Cassina still is one of the leading manufacturers of the LC3 Sofa and other Le Corbusier furniture styles, though reproductions from other maker are also generally accessible on the market.
