4 Chaise Longue à Réglage
Made by Cassina
Designed by Le Corbusier, Pierre Jeanneret, and Charlotte Perriand
Conceived in 1928 and presented at the Paris Salon d'Automne the following year, the Chaise Longue à Réglage Continu is among the most consequential objects of the twentieth century. Le Corbusier, Pierre Jeanneret, and Charlotte Perriand approached the human body as the governing measure of form, arriving at a silhouette that moves with its occupant rather than constraining them.
The chair's continuously adjustable recline is governed by a trivalent chrome-plated steel frame resting on a fixed base, with rubber-sheathed crosspieces providing quiet, stable support. Mechanism is made visible. Function is made beautiful. The structural logic is entirely exposed, reflecting the rigorous shared sensibility that all three designers brought to the collaboration.

Frequently Asked Questions
What does LC4 stand for in the Cassina LC4?
LC stands for Le Corbusier, and the number 4 designates this piece within the series of furniture developed collaboratively by Le Corbusier, Pierre Jeanneret, and Charlotte Perriand beginning in 1928. Cassina adopted this nomenclature when it began producing the collection under license in 1965.
How does the LC4's recline mechanism work?
The chaise rests on a fixed H-shaped base and tilts freely along a curved tubular steel frame, allowing the occupant to adjust the recline angle continuously by shifting their body weight. The position is held by gravity and the curvature of the frame itself - no mechanical locks are required.
Is the Cassina LC4 faithful to the 1928 original?
Cassina produces the LC4 under an exclusive license from the Le Corbusier Foundation and adheres closely to the original technical drawings. Materials and construction methods are updated only where necessary to meet contemporary safety standards, preserving the proportions and structural logic of the 1928 design.
What upholstery options are available for the LC4?
The LC4 is offered in fabric, leather, and hair-on leather (pony hide), each of which gives the piece a distinct character - from graphic and architectural to warm and sensorial. Upholstery is selected at the time of order, and the chair is made to order accordingly.
Who designed the LC4 - Le Corbusier, Jeanneret, or Perriand?
The LC4 was a true collaboration among all three: Le Corbusier, his cousin Pierre Jeanneret, and Charlotte Perriand, who joined the atelier in 1927 and brought particular focus to the ergonomic and domestic dimensions of the furniture program. Attribution to Le Corbusier alone, while common historically, understates Perriand's central role.
