I love my new mattress, firm yet very comfortable. No chemical smells ever. The reason it gets a nine is because there could be more support around the edge of the mattress. If you're not prepared you can get launched out of bed!
Great bed and super fast service! We had a terribly old mattress and I was in so much back pain. This bed arrived literally 24 hrs from the time I hit purchase. We've been sleeping great. Price point was perfect.
