It's only been a few weeks so it's a little too early to rate, but so far so good. Suggestion: Add an arrow to plastic bag pointing to headboard/footboard. This would position the mattress to the right spot before cutting plastic. Once that sucker inflates it's hard to position. Especially people doing it by themselves, like me.
This mattress is a great value. I have never slept more comfortably than I do with this mattress. I woke up with no back or neck pain after just the first night, contrary to waking up every day with pain after sleeping on my old mattress.
I also find that I don't wake up hot and sweaty during the night. Actually, I don't wake up at all until morning. I also find that I have been waking up in the same position in which I fell asleep rather than tossing and turning. All of this is in stark contrast to how I slept with my old mattress and how I sleep on a variety of hotels where I stay as I travel for work.
