We have had this mattress for a few weeks now and I can honestly say that I have slept much better. I used to wake up much more often throughout the night. I still briefly awaken with my usual hot flashes, but I can get back to sleep and sleep deeply. That is a significant change from our old mattress. This mattress has a nice, flat surface and supports my body well. I can sleep in any position (and I move often during the night) and I am comfortable. The mattress is neither too soft nor too firm, so it is very comfortable at the medium level. The only thing that concerns me is that I hope the memory foam doesn't flatten out and holds its shape for many years to come, and that we don't start feeling the springs poking us while we are trying to sleep! This is our first experience with a hybrid mattress and, so far, it feels great!
