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. You should always handle the lampshade by its fitting to avoid denting, marking, creasing or tearing the fabric. It is equally important to use the correct method and materials to clean it, taking care to avoid the excessive use of water, which may cause staining. Clean on a regular basis, switching the lamp off and making sure the bulb is cool before wiping the shade in a sweeping motion with a microfibre cloth, or brushing vertically from top to bottom with a soft brush or lint roller
