What is a synchro-tilt mechanism on a drafting chair?

A synchro-tilt mechanism on a drafting chair coordinates the movement of the seat and backrest — when the back tilts, the seat also tilts slightly (but at a different rate), maintaining the user's thigh angle and reducing the gap between back and seat. Standard tilt mechanisms only move the back while the seat stays level. Synchro-tilt is more ergonomic for extended reclining because it keeps the pelvis in a more natural position throughout the tilt range.
