The Tetra Chair is a sculptural seating object based on the geometry of the tetrahedron, one of the most fundamental forms in spatial construction. Fabricated from folded metal planes, the piece balances structural precision with visual lightness, functioning simultaneously as furniture and sculptural object. The chair has been exhibited internationally, including presentations during Milan Design Week and exhibitions in Chicago, New York, and Los Angeles. A Tetra Chair was also acquired by James Goldstein for the Sheats-Goldstein Residence. In conjunction with this acquisition, I designed a limited-edition publication documenting the work and its installation within the residence.
