I did not realize this existed or how helpful it would be until it was suggested while undergoing PT. I had tried other seat type cusions, etc. for driving and prolonged sitting and got no appreciable relief, the Lumbar Roll made an immediate impact providing comfort and promotong better posture. 4 stars

I experience pain and discomfort from Sciatica, and there was a point when it made driving almost unbearable. After doing proper stretches and changing how I bend and such, combined with the Mckenzie roll & tush cush, I feel much better. I noticed an immediate difference in how I felt while sitting the car while using this product. I recommend it to anyone with lower back pain. The only problem I have with the roll is the strap that comes with it. It doesn't do a very good job of keeping it in place on my seat, to the point where I just took it off the strap completely and just place it myself every time I get in my car. It is a minor inconvenience I suppose, but still worth noting. 4 stars

I have this McKenzie Lumbar Roll strapped to one of my desk chairs and I am trying it out there. I did try their suggestion of wearing it attached around the waist and then having access to lumbar support wherever I sat. I find it bulky and the elastic is too loose for this idea to work for me.
The roll is stiff and unforgiving. But if I am sitting in one position at my desk for a long period, then I appreciate the lower back support it provides. Probably could save money by getting a small, firm pillow for the same job.
I greatly prefer the McKenzie Super Lumbar Roll. 3 stars

My husband is using this and he has it in his car and it eases a lot of back discomfor when driving. He put the second one is his office chair for the same purpose. He is marveled at how such a little product produces so much relief. 5 stars

The Mckenzie Lumbar Roll helps me get the support I need while sitting for long hours at my desk. I recommend it to anyone with neck or back pain or discomfort. 5 stars
