I have had lower lumbar back pain, especially while sitting for 8hrs a day. A chiropractor recommended the Mackenzie Roll, I tried the two stiffness levels and personally liked the firmer one. My product arrived on time, it was wrapped and I inspected it. There were no tears, rips, or visible imperfections. I really like it and it does get uncomfortable in the beginning but once you use it for a few weeks it really makes a difference!
