To Charlotte Perriand, lamps were not a decorative element added for no reason, but a functional and technical component, a tool and an object answering to specific needs. Perriand's minimalistic approach instills a timeless character in her creations: these are the “Useful Forms” that came from the movement she co-founded in 1949. Like Perriand's furniture, her lamps are not immovable, but rotate and bend themselves, adjusting to our needs.
