Do comforters need covers?

Though a comforter comes ready to use and doesn’t need an extra duvet cover or similar protection, you can use one if you want to keep the comforter itself clean. Some people also do this if they want to change the look of their bedding. In this case, the comforter would work as the insert for the duvet cover.
