The S 320 combines the typical Gebrüder T 1819 materials, wood and tubular steel, to create a comfortable and elegant upholstered chair. Since its creation it has been used in numerous semi-public buildings, especially public and private event rooms. The front legs are made of solid beech wood bent in the traditional way; they are connected with a tubular steel frame. The ergonomically shaped seat shell fits into this basic construction. It is upholstered and can be covered with leather or fabric. For the semi-public sector the chair is stackable, can be connected with an additional element, and can be equipped with a writing panel.

With armrests. Frame made of solid stained beech wood or with cover varnish, and tubular steel chrome-plated or powder-coated. Molded plywood shell in stained beech or with cover varnish. Partial upholstery covered with leather or fabric.
