Wood is characterised by variations in grain, texture and colour, making each wooden furnishing a unique object. Vitra has strict quality standards for the woods selected for its products and uses wood from several trees for the manufacture of a single furniture object made of solid wood. As a result, every piece has a lively and distinctive appearance. The solid woods used by Vitra are mainly sourced in Europe and have an oiled or lacquered finish, depending on their application. Exposure to light will alter the colour of wood over time.
