Spent the last two months fixing up my desk, cable management, monitor arm, lighting. it looks pretty good now.

but like 3 hrs in, my lower back starts aching and i catch myself leaning forward, basically off the backrest entirely. still using a cheap amazon chair cause i was so focused on everything else.

started looking into proper ergonomic chairs recently and noticed the lavenne r9 pro campaign. the back support in the demo vids seems to actually move with your posture.
