This was not even close to what I thought it would be. Very flimsy--appeared to be loosely stuffed with dryer lint. I unzipped the outer cover hoping to find an inner cover of some sort, but sadly, all I found was a loose stuffing of cotton fluff. Didn't see of feel any of the foam I was expecting. I guess I read the stats wrong, assuming that the "Core construction of memory foam" along with the "Four layers of 1.5" high-density foam provide support for a better night's sleep" meant that there would be a total of 6 inches of high density foam. Not so.  There was no inner covering--all the cotton fluff was loosely packed in a very lightweight outer bag of the micro suede.  If you are looking for a comfortable mattress, that will wear well, this is not it.
