I'm really enjoying this mattress! I wish I could be one of the people who found that all their sleep issues disappeared the first time they lay down on this mattress, but I haven't been that fortunate--which probably proves that my old mattress was not the cause of my restless sleep. But I do find this mattress so comfortable! I bought it in Medium firmness, and it is exactly right. The mattress provides strong support, but with a slight sense of sinking into the mattress just enough to be cozy.
I read a lot of mattress reviews before deciding to order this one. And I was definitely concerned about the fact that you cannot return this mattress if you don't like it--while other mattresses offer very liberal return policies. But this mattress was hundreds of dollars cheaper than other mattresses I considered, and its reviews were as strong as or stronger than the reviews for those other mattresses. In the end, I'm glad I didn't fret too much over the no-return policy, because I'm completely satisfied and would never consider returning it.
