The down comforter arrived flat as a pancake, but once it was put in the dryer with some dryer balls, it was quite fluffy. It is very warm, a bit too warm for me and my husband, but better too warm than not enough. I love the fact that it can be machine washed. Also like that it is very lightweight and fluffy. So many down sold as King size are actually way too small for the duvet, but not this one. It fits perfectly!!!
