I have a 'flat' polyester duvet and have cut it up and sewn around each piece to make a mattress for DS2's dog. They are small enough to be washed in the machine and three of them in an outer cover will make her very comfy in her crate/bedroom.
I can't say whether a flat duvet is warm or not but at least old ones can be reused.
What would you put in Room 101?
