A coverlet and a duvet are both types of bed coverings, but they have some key differences. A coverlet is a lightweight, non-reversible bedspread that is usually either quilted or woven. It is designed as a decorative layer to go over thicker bedspreads, and it often has a thin layer of batting, making it appropriate for use as a stand-alone bed covering, depending on the weight. Coverlets can also be used as throws on a bed or sofa. On the other hand, a duvet is a soft flat bag filled with down, feathers, or a synthetic alternative. It is recommended that duvets are inserted into a removable cover, much like a pillow and pillowcase. Duvets serve as thick blankets to keep the user warm, and they are designed to be used alone (with no sheets) because the insert can be removed and the outer “bag” can be laundered. Many people like duvets because they reduce the complexity of making a bed, as it is a single covering instead of the combination of bed sheets, blankets, quilts, and other bed covers.
