I purchased these for a 13" deep Queen size euro top mattress.  First impression...beautiful chocolate brown color...first washing/drying they did well, fitted sheet fit the mattress snug & the queen pillow cases don't fully cover a queen size pillow (standard pillow they fit perfect)...the sheets were soft, warm and comfortable.  After 2nd washing/drying (as directed), the fitted sheet barely fit my mattress...couldn't even pull completely under corners, but they still stay in place. Other than being somewhat smaller than expected and/or shrinkage, these are made well.  If these end up shrinking more, I'll just use them on a full mattress.  I've never had this issue with flannel sheets before, but too I have ended up paying more.  For those with a mattress under 12" deep, there would probably not be an issue.
