what goes in a duvet cover

A duvet cover is a protective layer that slips over a duvet insert or comforter and has a closure, such as buttons, snaps, or zippers. It protects the duvet insert from germs and bacteria and can be easily removed and washed when needed. A duvet insert and comforter are effectively identical bedding pieces, soft, often cotton shells filled with lofty down or down alternative, that are ideal for use within a duvet cover. Most duvets are stuffed with fluffy, soft feathers or down, but they can also be filled with various materials such as fleece and synthetic substitutes to help give you a restful sleep and make your duvet cozy. The duvet should fit snugly inside a duvet cover, which can be removed and washed when needed. However, you can also use a duvet cover alone as an additional blanket or a top sheet.
