LC4 Chaise Longue

The LC4 Chaise Longue was designed in 1928 by Le Corbusier, Pierre Jeanneret, and Charlotte Perriand, and first presented at the Salon d'Automne in Paris in 1929. Dubbed the "relaxing machine," it features a curved, adjustable steel frame that rests by gravity on a black-painted H-shaped base, allowing the user to recline at any angle simply by shifting their weight. The design separates the seating surface from its support structure, creating an elegant mechanical relationship between the two elements. The LC4 represents the modernist ideal of furniture as functional equipment for living. Its ergonomic curve follows the natural reclining position of the human body, while its adjustable mechanism requires no levers or locks—gravity alone holds the desired position. Manufactured by Cassina since 1965 as an authorized reproduction, the LC4 remains one of the most coveted pieces of modern furniture. It embodies the perfect synthesis of engineering, ergonomics, and aesthetic refinement that defined the best work of the Le Corbusier studio.
