I had my doubts about any sheet that isn't 100% cotton, but these changed my mind.  They are so soft and smooth.  The bottom sheet is plenty deep for our tall mattress and I love the tags on the sides and top/bottom so you can put the sheet on right the first time (tagged top/bottom, side).  The top sheet is plenty wide and long, which is hard to find sometimes.  The pillowcases are plenty big for queen size pillows, which most aren't.  My only concern is that they may pill after many washings, but I won't know that for quite awhile.
