A comforter is a single piece of bedding with a built-in fill, while a duvet consists of a separate insert and a removable cover, which makes the cover easier to wash frequently.
A ready-to-go bedding solution. It is one single piece of quilted fabric containing a built-in filling (down, poly-fill, etc.).
Key Drawback
Harder to wash deeply as the entire bulky item must fit in the machine.
A two-part system consisting of a soft, flat bag filled with down or synthetic fibers (the insert) and a removable protective shell (the cover).
Key Drawback
Requires assembly; the insert can sometimes bunch up inside the cover.
How to keep your bedding fresh based on expert testing. Proper care extends the life of your bedding significantly. (See also our guide on cleaning a mattress.)
Remove the cover and zip or button it closed to prevent tangling. Wash the cover on a cold cycle. The insert usually needs washing less frequently (every 6-12 months) and should be washed separately from the cover for the best results.
Place the entire piece into the washer (ensure your washer is large enough). Wash on cold. For best drying results, tumble on low for 15-20 minutes to fluff, then lay out or hang to complete drying to prevent heat damage to the fill.
