I purchased this item based upon the reviews and...what can I say?  The best thing about it is it fits my bed perfectly with no sliding to one side or the other as my previous topper was want to do.  However....there is no discernible enhanced comfort to it (neither softer nor more supportive than my really old mattress) and I wake up in a sweat every morning - or at least for the 2 times I've slept on it.  Now I can't even find it on Wayfair's website so I'm hoping a return isn't out of the question.  My quest to find the perfect topper continues.
