I spoke with a salesman at Verlo mattress today, as i'd slept on a friend's Verlo bed and wanted to find out what's in it. He spoke of the 1" layers of foam in the pillow-top, one of which was memory foam. But the MF was in a middle layer; he said this is so that it doesn't make the person sleeping on it hot...Doesn't this negate its properties, though? I mean, doesn't MF need to be on the top layer, because, sensitive to heat, that's how it conforms to one's body and does its inherent job? Or can it have value being in a mid-layer?

Thanks for any input...;)
