We really like this mattress. We find it comfortable and like the  pillow top. The firmness has already helped us with our back pain. But we would consider this mattress, semi firm and not medium as advertised. It seems a little more firm than what we've experienced with other medium mattresses. The height is a really added plus providing greater comfort getting in and out of the bed. The quality seems excellent and good workmanship. One complaint we do have is that the edges are not that firm, and they sink when you sit on the edge of the bed. The cold gel feature really does work. It does not get as warm as our previous mattress did, which do not have the cooling gel technology. I would recommend this mattress for anybody who's looking for a semi firm mattress.
