It took me years before I finally learned what a Duvet cover was and what its purpose was for. This is the best thing ever for a king size bed because you put your big fluffy comforter inside it and when you need to wash it you just was the Duvet cover and the comforter inside it stays clean for years! The Duvet cover is light weight like a sheet. Its so easy to wash. Better than trying to wash a king size comforter. This one was a very affordable price for me and its well made and easy to slip the comforter inside. It has buttons on the end so I just button up the comforter inside it. It has little loops in each corner inside it to tie the comforter to keep it from sliding around but I did not use them and my comforter stays in place any way so far with no problems. I plan on buying more of these for the rest of the beds in our home so I can buy less expensive comforters to stuff inside these to make all the beds look really fluffy then put a printed colorful comforter on the top of them. Also this duvet cover was plenty big enough to fit my king size comforter inside it. Overall great buy and I highly recommend.
