Can I store my down- and feather-filled duvets in bed drawers during the day?

The bed drawers should be sufficiently sized to ensure that the down and feathers are not compressed too much. Moreover, make sure that the drawer is aired adequately.
 
The exclusion of air in bed drawers that are too small is bad for the duvets and pillows so that they wear out more easily.
 
If you place your duvets and pillows into bed drawers during the day, please ensure that they are fluffed up daily and aired regularly.
