This mattress exceeded my expectations, I was so happy with this purchase, it's made in USA and I can say the materials used was good quality. The firmness of the bed is just exact what i wanted. I've been using it now for like a week, no over heating. The mattress has 10 inches when I got it out of the box and wrapped around plastic (it inflated immediately like 30 minutes). No weird smell.  I love it and would buy it again for my mom!
