What does synchro-tilt mean on an office chair?

Synchro-tilt links the seat and backrest so that when you lean back, the seat tilts at a lower ratio than the back — roughly 2:1 or 3:1. Your thighs stay more level and your hip angle stays comfortable during recline, instead of tipping you backward uncomfortably. It's the standard mechanism on mid-range and premium commercial chairs. Multi-function mechanisms take it further by letting you adjust the seat and back independently. FindOfficeFurniture.com notes tilt mechanism type in every chair spec — call 888-719-4960.
