I have been doing the Mckenzie stretches and exercises for three years now-this has really helped me to deal with consistent back pain from a slight tear of a disc-and prevent further injury. Be careful when you try this on-they say you can't return it if opened and they run too large per the description. If you have anything less than a 40 inch waist you need to consider the medium rather than the L/XL. They probably need a few more sizes and they definitely need to do something about the strap. Otherwise it's probably going to work and I like the fact I can roll over with it on.

not real comfortable for sleep, I guess if I used them often I would adjust, it does seem to help back discomfort when back sleeping; I just cant seem to get a good nights sleep b/c it is kind of in the way when I roll over

This product does help maintain the arch in the back but I was hoping for a comfortable fit and it is not. Hard to sleep with it on. It is not contoured to fit well.

I used this roll for a month to try and ease my back pain caused by sacral fracture, but I didn't get any relief; so have stopped using it, unfortunately. It's good quality and good value.

I like the product but it was a bit to small. I can use it but its not as easy to use when it doesn't fit right. I would definitly recommend it but make sure you pick the correct size.
