Overall the mattress protector is sturdy, had no odor to it and fits around the mattress.  The negative is that it tends to get rather large wrinkles in it.  I thought at first it was due to the adjustable bed understandably making them.  However, even when the bed has been totally flat the big wrinkles are still occurring.  It detracts from the comfort.  Not sure if this is just happening to me or others.  The mattress itself is wonderful.
