I have been having lot of body pains especially hip and back pain and realised it's time to replace my year old mattress with a more firmer one and ordered this. I wish there was a way to try it before buying becoz most firm mattresses are not that firm but boy i was wrong with this one. This is firm as a rock lol. It's forcing me to sleep only on my back but as a side sleeper i can't do that. I wish i had gone with a less firm mattress instead.
