I had my doubts when it arrived completely compressed for shipping.  Then I removed it from the packaging and let it air in a spare room for a couple days before making up the bed.  I also put it in the dryer on low with a damp towel to air and fluff it up for about 15 minutes.  The mattress pad fits my 14" king  memory foam mattress perfectly.  It stays in place when sleeping and  while I can't say its equal to a feather bed it does add a pleasant layer of soft plush filling.  It seems very well made but I haven't yet laundered it so I'm hoping it performs as well as previous reviewers have said.  So far it's definitely  a keeper!!
