Size:Full What is a Duvet Cover? A duvet cover is a protective layer that slips over the duvet inset, comforter, or blanket, and has a closure. Because duvets and comforters can be expensive and difficult to clean, duvet covers are useful because they protect your comforter during use and are easily removed and easy to wash as needed. The duvet cover also allows you to change your style or color choice of your bedding with the simple switch of the cover. This allows for easy changes from season to season. Stay clean: No need to dry clean the comforter, simply remove the duvet cover, and clean with regular laundry. Comfortable: No need to sleep with a top bed sheet (Flat Sheet) as the comforter itself stays clean. The result is a super cozy sleep. Efficient: No need to remove the comforter in the morning, just straighten it out, as its part of the bedding. Hypoallergenic, good for allergy suffer: Easier cleaning means dusts and dirt don’t find themselves comfortable on the bedding = Better for allergy suffers.
