Very, very pleased with this purchase. I own an expensive down comforter for my bed, and I wanted natural fill for my son's bed without spending quite as much money. The quality of this comforter is excellent. The fabric his heavy and sturdy, the construction is excellent, and I'm expecting the feathers will stay inside (we also use a duvet cover).
Being filled with feathers rather than down, it is a bit "crunchier" than a down comforter would be, but I think this is definitely a great compromise if you can't spend the extra on down. It comes in a relatively small box, but puffs up very nicely. It's heavier than expected, which is a plus in my book.
My only quibble is that it does not come with duvet loops on the corners to tie the duvet cover on. Not a big deal, though--I sewed them on myself in about 10 minutes.
