Fluff your feather bed topper to allow the down fill to expand to its full potential. Place the topper on a flat surface and use your fingers and forearms to push the fill through the baffled boxes or channels so that it is evenly distributed.
Protect your feather bed topper with a cotton cover to extend the time between dry-cleanings or home launderings. These are similar to duvet (comforter) covers and may be secured with zippers, buttons or ties.
Air out your feather bed topper routinely. A couple of hours in a sunny spot freshens up the down fill and gives it more loft.
Gently steam the fabric cover of your feather bed topper if it becomes wrinkled. Never iron down bedding.
Dry-clean your feather bed topper when necessary. It's possible to launder this item of bedding at home. But, because it's easy to damage down bedding, dry-cleaning is preferable to home washing.
