How does lumbar support work on an ergonomic chair?

Lumbar support fills the natural inward curve of the lumbar spine (approximately L2–L4 vertebrae) to prevent the lower back from rounding forward during prolonged sitting. Adjustable lumbar support moves height-wise to match each user's spinal anatomy; lumbar depth adjustment varies the degree of support applied.
