This duvet is amazing! I live in the south so you never want a big fluffy comforter on you at night but a sheet is never enough. I purchased this duvet cover to use by itself as a cover. I got the King size for my Queen bed. As its already in the 90's here, and due to some of my medications, I sweat badly at night. This duvet, empty, is the perfect blanket over my flat sheet. In the winter, I'll just put my old quilt inside of it to give it a little more weight. The buttons stay closed easily. I couldn't be happier with this!
