I’ve always had real down comforters, and I love them and do wash them rarely, but they have to be replaced at great expense, and stop looking so puffy on the bed pretty quickly.  I bought this Down Alternative to put in my prettiest duvet covers just for show, since they look very nice.  The filling doesn’t shift and it does continue to look thick and puffy on my bed!  I tried sleeping under it and it’s also not as hot at night! I can’t say it feels like down, but it looks GREAT on the bed and is comfortable to sleep under.  Definitely recommend!
