When it comes to duvets and comforters, you’re bound to be cozy curled up under either one. Duvets, however, offer more options because of their covers. Duvet covers wrap a duvet insert, keeping it clean and well-styled; to update your look, simply pick a new cover. These covers are easy to wash, too, as they fit into the machine along with your sheets and pillowcases. Sold? Try this 100% cotton set on for size: finished in a crisp solid hue, with a 600 thread count, it includes a cover and two shams.
