This is our second set.  We tried the 1200 TC and had a couple problems.  The 1500 TC rock!  Very heavy, almost too thick for the summer.  Perfect for 34's of the year in Michigan.  We will never go back to percale or even 600-800 TC sateen.  These are SOOOO much softer after a few washes.  The more you wash them, they softer they get.  Yeah, they will smell a bit when you first get them.  Wash them one king size sheet & pillow case at a time.  We added a little vinegar and baking soda to the water & mixed it a bit before adding the sheets.  BUY THESE... you will not regret it!
