The mattress in general is good. My husband loves it, saying its like sleeping on cloud. I dont feel it though. Theres no discomfort, but it certainly hasnt eased my back pain much. Like some other reviewers mentioned, there are buttons in its surface that create some considerably depths, dents, which is not comfortable to sleep on. We bought a thick mattress topper to solve the problem. The mattress is categorised as firm, but compared with other products we have from the same brand, Id say, its more like medium firm. Weve only had it for a couple of months, so its hard to tell its life span. So far so good, but not that firm.
