What types of seat mechanisms are used on drafting chairs?

Drafting chairs use several mechanism types: (1) Standard tilt — seat and back recline together with tilt tension adjustment. (2) Knee-tilt — tilt pivots at the front of the seat (near the knees) rather than the middle, providing a more natural recline that keeps feet on the floor. (3) Synchro-tilt — seat and back move at different rates (usually 2:1 or 3:1), providing more ergonomic support through the recline range. (4) Multi-function — combines tilt, tilt tension, seat height, and often seat angle adjustments in one mechanism. For occasional use, a standard tilt works fine. For all-day use, multi-function or synchro-tilt mechanisms provide more ergonomic flexibility. FindOfficeFurniture.com — call 888-719-4960 for mechanism-specific recommendations.
