The Beams Chair is a lightweight wooden armchair inspired by the H-beam structure of the Golden Gate Bridge in San Francisco. The H-Beam structure is derived and used as a main design element in the Beams Chair, which shows the beauty of such construction. The main frame of the Chair is composed of two kinds of thin wood panel:multiplex and plywood. The two wood panels are combined together in such a way so as to offer directional perpendicular wooden structures and to create the H-Beam structure in the Chair. By such inventive arrangement of the wood panel, the specific H-beam structure is built up and an extraordinary stability of the Chair is ensured.

The Chair is made of three different kinds of wood, bent plywood, multiplex and aircraft plywood.The strength of the structure of the plywood and multiplex thin sheets is quite strong in one direction, while relatively weak in other direction.
By combining the two wood sheets in a way so to offer directional perpendicular wooden structures and to build the H-Beam structure, there are two strong dimensions so the anti-twisting ability and compression strength as well as the stability of the chair are tremendously improved.

The frame of the chair is constructed by bending plywood and multiplex. The flexible aircraft plywood covers the frame as the surfaces of the seat and back. Such design saves the molding cost of production and reduces the weight of the Chair.
