French born, New York–based Sébastien Léon Agneessens is a pluri-disciplinary artist whose practice pushes design into the areas of illusion and experimentation.

Known for his sculptural furniture, glass manipulation, and sonic sculptures, Léon creates pieces that feel at once primal and futuristic, functional and magical: tables that appear to hover, mirror surfaces that turn transparent, resin chairs carrying the texture of leather. Through his touch every object is conceived as both a functional design and a work of magic.

Inspired by the model of the Renaissance studio, Léon approaches design as a practice of perpetual invention. Glass is silvered, marbled, or deformed until it transcends its material logic; welded chains coil with serpentine tension; fiberglass becomes inscribed with cryptic alphabets.

Born in Blois (France) - the hometown of modern magic, and the final residence of Leonardo da Vinci - Léon’s work carries a lineage of illusion and invention. Each of his creations is a conjuring act, in which an object reveals itself through transformation.

Léon received an MBA from Bocconi (Milan), and started his career by pioneering the movement of curating contemporary art for brands through his agency Formavision. His work has been featured in The Wall Street Journal, The New York Times, Surface, ID, Corriere della Sera, and was the subject of a documentary for NHK Japan.

Léon is the recipient of the 2019 Fashion Group International Rising Star Award and the 2024 Galerie Magazine Creative Mind Award. He shows his design work with Ralph Pucci International.
