Mattress is everything as described! So comfortable, and you can definitely feel the cooling technology when you sink into it. When I got it, I opened it and let it expand for 48 hours without so much as sitting on it in that 48 hours. I didnt want to stunt the growth! It expanded to exactly 14". It is the best sleep I have experienced in years! Also the shipping was extremely fast. I think the delivery man had a hard time with the box because the top was completely open when it arrived but the mattress is shrink wrapped so that was not a big deal at all:-)
