While both, comforters and duvets, more or less fulfil the same purpose, they’re a bit different in the way that they’re crafted. The main and most important distinction is that a comforter is a one-piece soft furnishing while a duvet comprises two separate components. A comforter is generally quilted and comes with no cover. A duvet on the other hand comes with an insert or filler, as well as a cover for protection. However, the two can be used in place of each other, since they cater to the same need for warmth.
