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.
