Wood changes over the course of its lifespan, adapting to changes in humidity and light. Exposure to sunlight can cause changes to colour and structural over time, although mostly during the first couple of months of use. Wood breathes according to climate. Therefore, furniture should be placed in rooms with a relative air humidity of 40–50% and a temperature of approximately 20°C. Due to temperature and humidity sensitivity, we recommend treating wood during the winter months — preferably before and after the season. Furthermore, solid wood may become weathered or the fibres may rise slightly. Wipe clean daily using a well wrung cloth and clean water. Never use detergents, chemical cleaning products or harsh abrasives. Wood veneer is made from thin sheets of solid wood that are applied to a base of MDF, plywood or chipboard. As veneer is only approximately 1.2 mm thick it should not be sanded. Given that the veneer is made from real wood, natural differences in the wood can occur. Veneered surfaces should be cleaned regularly with a dry cloth. Avoid using water and damp cloths as these will damage the veneer. In case of spots or stains, removed with a well-wrung cloth. The surface must be dried immediately after removal so that no liquid of any kind remains.
