When you run your hand over these sheets, they feel a bit rough. It is like an illusion. When you slide into bed they feel like satin! So comfortable and smooth. The flat sheet seems over-sized. That is excellent if you have extra deep mattress. (I do not.) The fitted sheet goes on very easily. These sheets should be rated 4.75 stars. The only reason they wouldn't be perfect is the fact that they come out of the dryer a bit wrinkly. Not badly enough to warrant dragging out the iron. :) They are wonderful to sleep on. I definitely recommend these sheets and would buy them again.
