I am SO happy with this mattress. It is supremely comfortable and has relieved the aches and pains that I had before buying this one. I knew nothing about hybrid mattresses but after trying all of the different choices in the showroom my decision was obvious. I was sold on this one. Although it is very heavy to maneuver for changing sheets I love the loft. That would be the ONLY negative thing that I have to share, it is far removed from the positives.
