I have a 100% wool doona and it's pretty snuggly. Not flat or hard at all. I wash mine in the bath with wool wash and it's just beautiful. It's in storage ATM and I miss it so much. We use it summer and winter, it really is great.
It was exxie though, but I'd pay every cent again.
Oh and we have a king size on a queen sizzed bed so there is extra to snuggle
