It took several months for me to adjust to the new mattress. In fact, initially, I did not feel that I was sleeping any better than with our previous mattress. However, now I am sleeping much better, and I like the "soft" feel of the mattress; it is somewhat reminiscent of the waterbed I had when I was in my 20's, though not nearly as unstable! We bought this mattress to help my wife to be able to sleep better. She has major chronic pain issues, and she frequently had to sleep in a recliner instead of bed due to her pain. Now, she has been sleeping exclusively in the bed, and sleeping much more comfortably. She is a major fan! If she were writing this review, she would rate the mattress as "Great!" In short, we are both much happier now with our Helix mattress.
