Overall it is comfortable and my wife is happy, although I don't see us using this mattress more than a year or two. I've undergone two back surgeries and will have a third this summer (thus the desire to get a new mattress). This model is advertised as a 9-10 firmness which is what we wanted as our iComfort we bought 10 years ago was firm. This mattress is not firm. It is a 6-7 on the firm scale. We do like the mattress height.
