I opted for this mattress mainly because of its "cool" feature. I still felt a little warm, but it is cooler than traditional memory foam beds. The bed is fairly firm but is quite comfortable. I was somewhat disappointed because it slightly hangs over my box spring. It is about 3 1/2 inches to wide and 2 inches too long. I have deep sheets so fortunately I was able to force the mattress to fit them. The mattress went up to 9 1/2 inches deep instead of 10 which didn't make much of a difference to me. The mattress comes rolled up and is wrapped very well. I had to drag it through the slushy Chicago snow and it didn't tear or soak through the packaging.
