I hurt my lower back in November and was seeing a chiropractor for months and it wasn't getting better. After having this bed for less than a month, the support it provides made the pain go away almost completely. I love it. I am only giving four stars because I was expecting more because of the hype. I was hoping it would fix my problem of constantly being tired, but it does not. My boyfriend hated it at first, but he said he is finally having dreams again, meaning his REM sleep is back. Overall, I like this bed a lot. But is IS very expensive. I would however like to try the other mattresses
