I bought this for my 4 year-old daughter's full bed. The kids have been a little sick and they have been sleeping with my wife. So, I have had plenty of time to sleep on this. It is fantastic! I feel very tired when I wake up and in a good way. It is as if I am being pulled out of a deep sleep. I love it. I think when we go to replace our bed, we might just get one of these. We were looking at a Tempurpedic, but this is a fraction of the price. I know it is not quite the same, but compared to a spring mattress, it is just awesome.
