Bests & Worsts Reviews from Amazon

I tend to congest all of my stress in my cervical and thoracic vertebrae. I can pop my c4-c7 easily on my own. I have issues with my thoracic vertebrae and usually need assistance. I had to put a silk cover over it before laying on it because the balls are a rubbery material that was sticking to my hair which didnt allow me to "slide" down. With the cover I could maneuver better and it seems like it may help me keep my C's in line but make my T alignments more noticeable.
