I love Northern Nights and Malden MillsPolar Fleece sheets BUT! I have a queen size pirahana sleep mattress (very expensive) but only 13" deep. Most sheets now will fit mattress's to 17" or more and while they fit they slip up and look like clothes that are two sizes too big. I like sheets hospital tight. I won't buy your sheets and have to search cheap sheets most of which are now also to deep. The polar fleece I bought from you a few years ago were not deep and I loved them!
