Have been sleeping on my new Helix Twilight Luxe mattress for about one month now, I do sleep better but not great. My back pain is mostly gone but my neck and shoulder pain while it has improved some is not completely gone as I had hoped, but since I am a side sleeper I guess it is expected. Overall, I do like my new mattress and I was use to a very firm mattress and this one is medium firm I do see a different in my sleep as both husband and I are sleeping longer and deeper so it has helped. The mattress does sleep hot at first but within a couple of weeks we adjusted to it and now it seems much better, I even got the cooling gel top for the mattress and it still was very hot to sleep on for the first couple of weeks, but don't give up it does adjust to your body and now there is not an issue with the heat. Overall, it is a good mattress.
