I can truly state that I am very happy with my new Sweetnight mattress.It is firm but not overly firm.It sleeps a little warm but not hot and I LOVE it ! It was delivered promptly and arrived safe and sound. Unpackaging was straight forward and I following the included instructions.I waited 72 hours to allow the full expansion of the mattress and it is indeed a full 12". I like this pillow top very much as it is not overly soft but instead allows some compression and then it firms up gently. 

Overall, I would recommend this mattress to anyone who does not want a spine damaging "soft" mattress and likes to sleep in any position. I am sleeping on my tummy again, something I haven't done in so many years. You know it's a good mattress when you like going to bed instead of "staying up".
