Shell in plastic composition with up to 25% wood fibers. The wood fiber and plastic blend is injected into the mold, forming the chair's shell. The shell's inside is then upholstered with foam and fabric. The fabric is glued to the shell's surfaces and stapled using a pipe on the edges. This ensures a smooth and tight surface of the textile. Wood base is cut from solid Oak wood and water-lacquered. For Stained Dark Brown version only: Please note that slight color variations can occur due to the inherent characteristics of the material.
