We have had our mattress for about 3 weeks and it has been a dream. It really holds your body and prevents much of the tossing and turning. The firm is not too hard and actually feels more like a medium. Maybe it is just me, but I have been dreaming like crazy! When I am out.....I don't move until the morning. Expensive, but worth the price. At first it was a little difficult to turn over, but once I figured it out.....all good. I was worried about the heat (live Hawaii),, but it is not a problem.
