These sheets are so soft and warm it is near impossible to get out of bed in the morning.  I actually purchased these to get my seven year old sleeping in her own bed all night and they worked like a charm. She actually sleeps in until I make her get out of bed.  Teenagers I expect to act that way but 7 year olds, that makes me think those are some special sheets.   

Pros: appear to wash well,
Cons: none that I know of
