The Hundred-Year Chair
An open design dossier following a chair from historical precedent through salvage-built prototypes, technical drawings, and a truss of two congruent triangles.
Field notes
The project compares three chair designs through shared drawings, cut lists, photographs, and a dated lineage rather than presenting a single finished object. Its Keel Chair uses a truss of two congruent triangles, five square-cut boards per side, twelve identical brackets, and a cherry spine beneath black film-faced plywood. A separate technical layer records why bolted joints go slack, how wide the keel must be, and whether each claim is verified, standard, derived, or unverified.
