Twin brothers Simon and Nikolai Haas run their eponymous furniture design and fabrication studio out of Los Angeles, from which they create everything from set design to wearable art, masks for Lady Gaga to gold-leafed furniture for Louis Vuitton stores. Nikolai apprenticed as a master carver and Simon studied blacksmithing at the Rhode Island School of Design—and together their pieces, while sleek, still retain some traces of artisanal handiwork. Their seating and vessels often combine futuristic finishes with biomorphic forms.
