Construction stripped to an all-wood frame with a sculptural, pared-down profile. A rounded back sits on slim uprights for targeted contact at the upper spine while the rest of the chair stays open enough to move easily around a room. The seat dips slightly and cups the sitter, guiding posture without padding to maintain, and four legs splay outward a little to widen the base. Where the back meets the seat frame, the joint runs straight through to form a single stiff spine that holds firm under a lean. It measures 17.75 by 21.5 by 31.5 inches. Four-chair minimum.
