HTB5B Backrest For First Chair : My back feels a lot better now.

I had bought this backrest to fit my Tama First Chair stool as I have been suffering from back pain for many years.

Installation was pretty straightforward and I could immediately feel more comfortable on my stool. I really like the fact that it can be folded for easy transport and use the lower part of the backrest as a handle for easy carrying. The only thing that I don't like about this backrest is that it does not move forward enough to fit my back snuggly. I solved this by putting a piece of perspex beneath the adjustment knob to act as a spacer so that the backrest can move forward even more when tightening the knob. Other than that this backrest is great and I can feel less pain in my back.
