Why you should trust us As part of our research for this guide, we interviewed Shannon Maher, an assistant professor in the Home Products Development department at the Fashion Institute of Technology, and former product designer for The Company Store . She helped us with our testing strategy and gave us useful information on bedding fibers and construction. We then looked closely at customer reviews on various department store and home bedding sites. As a sleep writer at Wirecutter, I’ve written many guides, including those about blankets , flannel sheets , and robes . I’m a quilter and quilt designer with more than a decade of experience making, washing, and using blankets and other bedding. I know what well-made bedding should look and feel like, and I know how to create a cozy, comfortable bed. Duvet vs. comforter If you’re looking to cover your down or down-alternative comforter , you may be confused by the term “duvet cover.” T
