It's a fantastic mattress cover all around.  I'm not doubting its claims, because I'm sure it does what it's supposed to.  My issue is only a slight one.  It brags about being soft and unnoticeable.  It's noticeable.  Don't get me wrong!  It's not like sleeping on crinkle paper!  But, you can feel it.  Especially in those cases where you can't quite sleep, and you toss and turn.  My wife has far more experience with these mattress covers.  She grew up with them on all the beds in her house   she says this one is by far a better quality, and better feeling.  So, there's that.  Overall it is good and we enjoy it.
