I purchased this mattress almost two years ago after suffering with back pain for 5 five years. Within two weeks, I was waking up without pain and getting a good night's sleep, not tossing and turning to get comfortable. It is semi-firm, but conforms to your bady shape within minutes of getting in. It took a couple of weeks to get used to the temperature change as well. The memory foam is quite a bit warmer than a regular mattress and it was noticable for the first few weeks, but once that adjustment period was over, it's perfect. I absolutely love this mattress and hate that when we go to a hote or on vacation that I can't take it along. There's nothing like it.
