Love, love love these sheets.  Super soft.  Smell of "ink" gone after just one wash.  I swear my boyfriend rolls around in bed like a steamroller all night and no sheets ever stayed on.  These have a built in elastic to hold sheet in place (sorta like the suspender clips you can buy to add to a sheet to keep it on).  Not one single corner has pulled up.  I ended up buying two sets and I think I'm going to buy 2 more.  Nothing better!
