I’d like to chime in here. Posture is terribly important. No chair can help fully if there is dis or misalignment (maybe even from previous chairs that gave you bad posture)

It is mentioned in the article briefly, and I feel it is a missed opportunity to discuss it.

I currently use a series of exercises that I designed specifically for combatting the ails of sitting, and it has been a big improvement. The chair i use matters less now.
