My wife and I very happy with our mattress. She doesn't wake up with backaches anymore and I sleep very well. We had a 3" memory foam top that we put on that made the hardness just right, otherwise our medium hard choice might have been a little too hard. The only drawback was that the dimensions were off by 3" on the length and 2" on the width (from the listed dimensions), which made it a little too short and wide for our bed-- although we can live with the difference. Overall we are very happy with the price and the mattress and would buy it again.
