I went from a memory foam mattress that was killing my hips and back nightly to sleeping on this. It was so much better after just one night. I have now tried it for two weeks and I still am sleeping great! I don't toss and turn or wake up sore anymore. It is amazing what a good mattress can do for your sleep. I am highly satisfied with this mattress and I definitely recommend it. [This review was collected as part of a promotion.]
