I purchased the Nashville 300TC Floral 100% Cotton Sateen Sheet set in blue, for a very thick mattress and the sheets fit very well. in my opinion, these sheets are nice and soft.  They do wrinkle a bit after washing but not too much.  I love the design which looks as nice in person as it does online, maybe even better.  I have received compliments.  I purchased another set for a friend who really liked the design.  He said although it was floral, it wasn't overly feminine and fit his mattress very well.
