Using your double - bed cotton duvet is easy. Just place it on your bed and fluff it up to spread the filling evenly. For regular use, it provides a cozy and comfortable sleep environment. When it comes to maintenance, it's recommended to have it dry - cleaned every few months to keep it fresh. Avoid exposing it to direct sunlight for long periods as it may fade the cover. If it gets a small stain, spot - clean it gently with a mild detergent. When storing, make sure it's completely dry and place it in a breathable storage bag to prevent mold and mildew.
