To use this duvet, simply place it on your king-size bed. It's suitable for milder weather, providing just the right amount of warmth. When it comes to cleaning, it's best to follow the care instructions on the label. Usually, a gentle machine wash on a low setting is okay. Avoid using harsh detergents. To keep it in top shape, fluff it up regularly, especially after washing. This will help maintain its loft and ensure it stays soft and cozy for years to come.
