I know it's a firm mattress, but I was expecting a little bit more cushion on top, from the diagram. It's actually quite difficult to tell which side is the top, because there's almost nothing after the springs. If I dig in with my finger, I can even feel the positions of individual springs. But it's fine to sleep on. Also I gotta say, it was impressive how small the box it shipped in was. idk if that's specific to this mattress company but they compressed the sh** out of this thing and rolled it up tight, which was pretty convenient.
