I bought this to go with the 7 inch firm foam mattress on this site and the combination is awesome. Very comfortable--soft and then highly supportive together. There was a little odor but not bad, I had no space in my apartment to unroll and air out for 48 hours but it was fine and I'm pretty sensitive to scents. I'm not sure if it will fulfill its "coolness" promise in the summer. It seems really cozy, though not sweaty hot here in the middle of winter.
