Low Side Chair in sleek Argentine Rosewood from Costantini, Umberto

Costantini is a furniture design and manufacturing company founded in 2002 by artist and designer William C Stuart. The name Costantini comes from his maternal grandfather, a first generation Italian-American. Born in New York City and raised upstate, William majored in studio art at Colgate University with a year abroad in Paris, graduating with honors. In 2001, he traveled to Buenos Aires and fell in love with the culture and craftsmanship instantly. He designed his first collection soon after and opened an art and design gallery in Los Angeles. A decade later, he came home to New York and now has a studio in the famed West Chelsea Arts Building where his works blur the lines between art and functional design. The team of artisans continue to produce the majority of the furniture in Argentina. Aside from private collections, some notable public projects include the Hotel Bel Air, the Sultanate of Oman, Bergdorf Goodman, NoMad Hotels, Four Seasons, Ritz Carlton, and Grand Hyatt. Our work has been featured in publications such as Architectural Digest, Galerie Magazine, the Wall Street Journal, Interior Design Magazine, Luxe, and more.Visit us at our New York studio, open by appointment.
