was using old gaming chair during MCO period, sitting down 6 to 7 hours per days really made my lower back and butt area extremely pain. After intensive research and finally decide to get Ergohuman from Amoffice, after less than a week sitting on that, most of my pains are gone.

When you are young, sitting of any chair are fine, but when older age, these things really matter.

I think is the V1 from the look of the arm support.
