These sheets are very nice.  I washed them as soon as we received them and they performed perfectly!  I dry all my laundry on the absolute lowest temperature setting and I don't usually have issues with excessive wrinkling.  It would be unrealistic to expect cotton sheets to come out of the dryer completely wrinkle free.  They stay put on the mattress, feel great, and the weight it perfect.  A nice bonus:  I received them before the estimated delivery date
