We are combo sleepers. But wanted more support for back sleeping. We added the luxury mattress pad to soften the firmness. I have been sleeping very well and have not experienced any back pain so far. So high grades for the mattress in month one. In a year or two I'd like to report back. One issue I do have is with the two free pillows that came with the bed. They are hard and not in the least heavenly. I have had a stiff neck every night. A new expensive down pillow arrives tomorrow. Advice to Helix is don't offer a freebie unless its has quality and is worthwhile. It gave me a queasy feeling about the quality of the bed underneath.
