The superb aesthetic appeal of the S 843 derives from the accent on the separation between seat shell and frame. The cut of the surfaces on the moulded-shell seat evokes formal analogies to automobile design, where this method is applied to car-body workmanship yet transposed at Thonet to the material of wood. The result is a clear, elegant silhouette. Thanks to its immodest aesthetic standard, the S 843 recommends itself not just as a conference chair but also as a high-quality furnishing for a lounge setting or for a private dining or work area.
