Hah! How about this: So they don’t end up injuring themselves.
There’s a reason why ergonomic chairs exist and why they all follow the same exact design rules (to varying degrees).
Most important features, in order of importance:
Adjustable arm wrests. Height is more important than swinging out/in. The out/in feature is more for convenience of getting them out of the way on occasion than anything to do with ergonomics.
Adjustable height. The base of which all ergonomic chairs were developed.
Adjustable lean. Meaning: You can control how far back it tilts.
Also important: Men and women have different ergonomic requirements! A woman’s spine is curved and should not have the chair configured the same as a man.
I mean at the base of the spine. Also, women’s ischial tuberosities are farther apart and the weight distribution is completely different. This means that ideal ergonomics for women require narrower, contoured upper back rests as well as a lumbar pad due to that deeper, inward curve at the base of the spine.

Everyone’s spine curves. It is just more pronounced in women because of their other curves. If you don’t have lumber curve, you’ve got scoliosis.

Hence why ergonomic chairs are so configurable.
