An upholstered shell cut close to the body on a compact, steady stance. The backrest reclines gently to follow the curve of the spine, and tufted stitching holds the shape together while spreading pressure evenly across the back. The seat tips at a slight pitch and carries padding sized to support natural posture without bulk. Four tapered legs at a modest outward angle keep it stable, and the shell attaches to a rigid frame so the cushioned form sits firm rather than loose. No arms and a trim outline mean it slides easily at tight tables. It measures 19.75 by 23.5 by 33.5 inches. Four-unit minimum.
