About the designer

One of the great young designers of the moment, native New Yorker Todd Bracher has earned worldwide attention for his furniture and product designs.

Bracher teamed up with Humanscale to create the striking Trea multipurpose chair, which mimics the instinctive recline of the human body without resorting to manual controls and the innovative Vessel light.

A Pratt Institute graduate, Bracher earned his MFA in interior and furniture design at the Danmarks Designskole in Copenhagen after winning a Fulbright design fellowship. He was named 2008 New Designer of the Year at New York’s International Contemporary Furniture Fair and has been twice nominated for Bolig’s International Designer of the Year Award. He has global experience, having headed up Tom Dixon's Design Studio in the UK, acted as a Professor of Design at the l'ESAD in France, and worked as Creative Director of luxury Scandinavian brand Georg Jensen.
In 2007 Bracher returned to New York after spending a decade overseas and founded Todd Bracher Studio in Brooklyn.
