What types of lumbar support mechanisms exist on executive chairs?

Executive chairs offer several lumbar support types: (1) Fixed lumbar pad — built into the back at a set position; works for users whose lumbar curve aligns with the pad's position. (2) Height-adjustable lumbar pad — slides up or down a track to align with your specific lumbar curve; the most versatile option. (3) Inflatable lumbar — a pump mechanism inflates or deflates a bladder to adjust depth of support; very precise but less common. (4) Contoured back — the entire backrest is shaped to provide lumbar support through its curve without a discrete pad. For ergonomically optimal all-day support, adjustable (height and ideally depth) lumbar support is the gold standard.
