Backboard Stretch Adjustable Lumbar Support
I have been using this product for about 3 weeks now, and have definitely seen a significant difference it has made in reducing my lower back pain.
It was a bit uncomfortable to start with, and only tried 5mins in the morning. Now on 5mins in the morning and after my work has finished sitting at my desk, I use again.
I am going to try going up to level 2 in the next few weeks, just to see if that improves my back stiffness and pain further.
Would definitely recommend this product, and it's been a great buy.
