I think I might actually like the comfort of this one above my select comfort mattress; however, I've been sleeping on a hard wood floor for a couple weeks, so I might be a bit skewed. The memory foam in and of itself tends to be a bit warmer than what I'm used to. If you don't like to feel a warm mattress, you might want to watch out, but it's very comfy. I did order a twin and ended up getting a Cal King. It created some issues because I had already bought twin sheets, but I guess I'm not complaining. I have a big mattress now!
