Using these chairs is super easy. Just place them where you need seating, like around your dining table or next to your desk. They're light enough to move around as you like. When it comes to cleaning, use a soft, damp cloth to wipe the seat and backrest. Don't use harsh chemicals as they might damage the PU material. For the steel legs, a dry cloth is usually enough to keep them shiny. As for maintenance, check the legs regularly to make sure they're still firmly attached. If you notice any loose parts, you can use a simple tool to tighten them. Keep these chairs away from direct sunlight for long periods, as it might fade the colors. With a bit of care, these chairs will serve you well for a long time.
