The LC 4 chaise longue is a design classic, an icon, and the ultimate in relaxation: its form promises pure comfort. Designer Le Corbusier achieved the perfect balance between geometric simplicity and ergonomic function. The chaise longue is upholstered in black genuine leather and can be easily adjusted to a reclining position using its runners.
