PROS: The delivery amazed me. It worked exactly as they said. It's really comfortable, not too soft or squishy, about what I expected out of a medium. CONS: I don't like that I can't flip it over, and the sides slope down a bit (not a whole lot). My roommate got a soft, and the sides slope a lot more on hers. My old mattress cover didn't fit on the 12" mattress, but that was more my problem than the mattress's.
