Posture is not the villain you were told it was
No single sitting position causes back pain. The position you hold for four hours without moving is a different matter.

What the studies show
Large reviews have failed to find a consistent link between a particular sitting posture and back pain. Slouchers and sitters-up-straight get the same amount of it.
What does matter
Time in one position, total load across the week, sleep and stress. Movement variety beats any single ergonomic rule.
A practical rule
The best posture is the next one. Change position roughly every half hour and the chair matters a lot less than you think.
