The wood we use for our furniture originates from certified wood suppliers from Europe and America and has a high quality. Therefore all our wooden products have a high level of craftsmanship and an authentic look and feel. The bert plantagie wood collection consists of the following types of wood: oak and walnut. These wood types can get a clear oil or varnish finish. Oak and walnut are available in two different qualities: premium or knotted. The knotted version is more robust (and cheaper) than the premium version. Do you like stained wood? A number of the bert plantagie wood types can also be executed in clear oil and varnish, or in various wood stain colours. A layer of clear varnish or oil is added to all wood stain colours.
