It's so hard to say because whats comfy for me may not be comfy for you. I currently have a Kingcoil inner spring mattress with 2" pillow top. But I also have a thick down feather mattress topper, plus another 2" memory foam topper on TOP of all that LOL. That's from all the desperation before I knew what was wrong with my spine. It's a firm mattress, but firm kills me when my shoulder bothers me (as I sleep on my side) and sometimes it killed my back, though soft was worse. So I have firm, with layers of softness on top of it. For me it's comfortable when I'm not having alot of pain. When I have severe pain, absolutely nothing is comfortable. I've thought about the air beRAB or memory foam beRAB, but they are soo expensive and I would probably not be comfy on those either when in alot of pain. But everyone likes something different. I wish I could have helped you more in your decision.
