Very happy with purchase so far. I'm sleeping much better and I'm more alert in the mornings (though I don't think you will ever be able to describe me as a "morning person). Bed provides solid support for my back. Only possible complaint is I sometimes wake up hot, but I think that has more to do with my sheets/blanket than the bed itself. A solid purchase.
I've had the bed for a little over a week, and so far it's been super comfy and I fall right to sleep. The only problem I had was receiving it. I ordered on the 31st, has some issue to validating who I was solved by the 4th and finally received it the 11th. Not really the 2-5 business days advertised. It would have been okay, except I was sleeping on the floor while I waited (I moved out of a place and owned no bed).
