Really impressed with how well it is packaged. Once it is opened it expands slowly into the most comfortable thing that I've ever rested on. 
I have had issues with my lower back and hip for quite a bit of time, more than 10 years, and have not found the exact firmness or softness I needed to feel comfortable while in bed. With this topper, I feel the firmness of my mattress and the contour of the topper. 

I highly recommend this topper if you are hurting while you're asleep.
