A duvet cover is a protective and decorative fabric case designed to encase a duvet, which is a type of blanket filled with down, feathers, or synthetic materials. Duvet covers come in various sizes, colors, and patterns, allowing individuals to easily change the look of their bedding without needing to replace the entire duvet. Using a duvet cover helps keep the duvet clean and can be easily removed for washing. Most duvet covers feature a closure, such as buttons or a zipper, to secure the duvet inside. This makes maintenance simple and helps extend the life of the duvet.
