Using this duvet is easy. Just put it on your queen - sized bed and you're ready for a cozy summer sleep. When it comes to maintenance, it's best to have it dry - cleaned to keep the down and feathers in good condition. Avoid machine - washing it too often as it may damage the structure. Also, make sure to air it out regularly to keep it fresh. And if it gets a bit lumpy, just give it a good shake to redistribute the filling.
