The design of extending the pocket size of the fitted sheet to 14 inches will fit with the most of mattresses. *We recommend duvet covers because they can be washed much more often than can your quilted comforter. Too-frequent washing (even dry cleaning) can compromise your comforter's down fill. However, a cotton duvet cover can be laundered along with the sheets and pillowcases. This keeps the down comforter fresh as well. If you have ever priced dry cleaning for a fine comforter, you understand why cleaning it less often is a huge advantage!*Another advantage of cotton duvet covers is that they are changeable, so you can change the look and feel of your bedroom without having to completely redecorate.
