A duvet is a type of bedding consisting of a soft flat bag filled with either down, feathers, wool, cotton, or synthetic fibers such as polyester batting. It is usually called a comforter or quilt in American English, and a doona in Australian English. The word "duvet" is of French origin, meaning "down". Duvets are often more commonly known by other names outside of Europe, such as "ralli quilts" or "razai" in Asian countries like India and Pakistan.
A duvet is different from a comforter in that it has a unique pillow-like structure that traps heat without weighing you down. The duvet insert is made up of a quilted shell filled with natural or synthetic filling, such as down or down-alternative, that is protected by an interchangeable cover. In contrast, a comforter is generally used to refer to a slightly different type of bedding that is not as thick, does not have a cover, and is often used over a top sheet.
A duvet cover is a fabric case that fits around the duvet and closes with buttons, snaps, or zippers. It allows for easier washing, flexible design, and even a different feel under the covers. Duvet covers are easily cleaned and compact for storage.
In summary, a duvet is a type of bedding that is filled with soft materials and protected by an interchangeable cover. It is different from a comforter in its unique pillow-like structure and the fact that it has a cover.
