Specs on Overstock.com site reads: Duvet cover: 108 inches wide x 90 inches long. When Duvet arrived, the specs on the package read: 106 inches wide x 92 inches long. Needless to say my new down comforter does not fit. I ordered the All-season Luxurious Down Alternative Comforter from Overstock. That size was correct. You wouldn't think a few inches make a difference, but they do.
