For our furniture we use high-quality FSC®-certified pine from Norway and Sweden (Pinus Sylvestris). Owing to the cold climate the trees grow slowly and can only be felled after 80–120 years. This means that Scandinavian pine is harder and more suitable for outdoor furniture than pine from warmer areas, which generally grows 3–5 times faster. Scandinavian pine has a hardness of 1,7 on the Brinell scale. Scandinavian forestry is amongst the most sustainable forestry in the world. The felling of virgin forest is prohibited by law and, consequently, timber production in Scandinavia has doubled over the last hundred years, with an annual increase in stock of 10%. Vestre's timber is impregnated with natural linseed oil which offers lasting protection against rot and virtually maintenance-free use. After some time outdoors, the surface will develop a grey patina.
