The Camden Duvet Cover Set by Stone Cottage's 210 thread count is just the right number for efficient comfort. In fact, it's a little like Goldilocks. Not so low that it's uncomfortable, yet not unnaturally high (with a price tag to match), the thread count on this duvet cover set is just right. Made from 100 percent sateen cotton with polyester fill, this three-piece set can be easily washed whenever needed.
