Have the mattress purchased in late 2013, previously had a spring mattress and can therefore quite well give my judgment. The first two months were "ok", so mind you ok, this wow effect all write like here in the Rezesion has not used. From 3-4 month I got problems with my left shoulder, I still when I wake up trouble. This is far worse off, that I and my wife every night so sweaty that I must even stand must un change my shirt. I also feel, not to be rested properly, the same with my wife. I'm with the mattress which is more than dissatisfied and probably a new mattress (probably again innerspring) buy. There is nothing to fault of the supplier, all Top because I would order again.
