Most furniture depends heavily on one of two basic shapes: the rectangle or the triangle. Robert Frazier's designs represent a break with those traditions.

Underlying the surprising angles and lovely use of materials is a patented joint, an edge-lapped tetrahedral joint that joins three elements in a range of acute or obtuse angles. Among the pieces you'll see here are tables and stools of various heights executed in wood, aluminum, and glass. In these pieces, the joint itself is the apex (and center) of a tripod; the floor serves as the base of the lower tetrahedron, and the table or stool top serves as the fourth side of the upper tetrahedron.

For the tables, glass provides an unusual view of these intriguing angles.
