The mattress is a fantastic balance between firm and soft, it's supportive, and puts no stress on sensitive points on my body.
The only reason it's a 9 instead of a 10 is it doesn't keep quite as cool as I would like, but it's so much better than the pillowtop I was sleeping on before.
So far I love the way the bed feels. But the SMELL is pretty bad. I still haven't slept on it. It lays in the spare room. Everyday I go in and lay on it for a bit. And every day I take the sheetback off and let it air another day. It is getting better but I had NO IDEA that I would have to wait some weeks before sleeping on it.
