This is in no way 600 thread count. It's scratchy. I have a 600 count duvet for my queen, so I have something to compare. It feels coarser than my son's, which is 100! It seems like from what I've read, that some people are getting a high quality high thread count duvet, while others are reporting something totally different! I'm really disappointed and it seems like this seller is running a scam selling several different quality duvets under the same product info. It's a gamble.
