Unfortunately I've already had to wash this comforter a couple of times, (thank you dogs). The filling inside compacts like mad, to the point where the corners crumpled and were bouncy like elastic. I've never seen anything like it before. I had to go through the blanket and pull the stuffing apart through the fabric to get it to lay flat again. 

For the obscene amount of money I paid for it, it really seems unacceptable that something machine washable/tumble dry would react like that. It's been so much work. 

Positives are that it is beautiful, and will keep you toasty.
