I ordered this as it was supposed to be a firm orthopaedic bed. Don't get me wrong, the mattress seems like excellent quality, but I would not rate it as orthopaedic nor firm, although it is reasonably comfortable. The mattress really needs better edge support, when you lie or sit near the edge, it just collapses, unlike previous mattresses I've had. Personally, I would not rate this mattress as firm, I would rate it as soft based on my experience.
