Pratesi. A wise investment
All Pratesi products are great, but expensive.
I clean my comforter (it's a king size) in the steam dryer. I
put in in the dryer with a couple of cheap tennis shoes in clean socks to help fluff it up. Some can be washed, but take forever to dry. If you can put it in the sun, that seems to freshen and fluff it up.
If you buy a new one, try to get at least 650+ fill. Now is a good time to buy, as they are often on sale.
