I know the Herman Miller/ErgoHuman gets recommended alot. I know shelling out for a chair is important since you spend a lot of time in it. Right now can't afford that. What would be the difference in ergonomics be in getting something like a Herman Miller vs a chair like this (https://www.officeworks.com.au/shop/officeworks/p/baku-mediu…) and a lumbar cushion?
i'd recommend secondhand herman/steelcase/haworth/ergohuman
