Just put this duvet cover (king size) on a brand new king sized duvet. The bed is a queen, but I like lots of drape and this cover does not disappoint. Like some others have mentioned, the material is on the thin side but as I was slipping it over a fairly heavy weight duvet, I didnt want a heavy cover too. It fits the duvet perfectly. As I havent even slept under it yet, I cant speak as to the durability of the coverhoping to get at least a few years use out of it. The price was very reasonable though, so even if it only lasts a year or two, I wont feel cheated!
