I love this duvet cover. I ordered a King size. I have a Queen sized bed with a pillow top temperpedic mattress, and I find that Queen sized comforters and covers end up being too short because of the thicker mattress. My current comforter fit easily into the duvet cover and is well secured by the hidden button closures. The set also comes with two pillow shams . It's a good quick upgrade to any room without having to buy a completely new bed set.
