What is the correct armrest height for an office chair?

The correct armrest height places your forearms horizontal with your elbows at roughly 90°, shoulders dropped naturally — not elevated. When at the keyboard, armrests should be at or slightly below keyboard height so you can slide the chair in close without armrests bumping the desk edge. The biggest mistake users make is setting armrests too high, which chronically elevates the shoulders and causes neck and trapezius muscle fatigue. If you can't achieve a relaxed shoulder position with armrests in, try flipping them up or removing them temporarily as a diagnostic.
