Our past few sheet purchases have been in the 800 - 1000 thread count range, so I thought more thread count would be better. Wrong. The sheets are heavy, which I expected. They are also as rough as a burlap sack, however. I was not expecting this. So, ultimately I don't have enough experience with 1500 tc sheets to know if this is simply a characteristic of 1500 tc sheets or this particular brand. Either way, I will purchase 800 - 1000 tc sateen sheets next time.
