Dr Oz should do better then this!! Like I've read in other reviews, this isn't a 12, more like a 10-10 1/2. The plush is really soft, which I love but it's the hottest bed I've ever slept in, have to have the ceiling fan, stand up fan & my A/C blowing or I wouldn't be able to handle it. I've had it for a few months and although it hasn't helped my back at all it is comfortable like a cloud. Thank you
