YES YS-84 Mid Back
The Office Master YES YS-84 is the mid-back YES chair with a synchro mechanism, same mesh back and cushioned, saddle-contoured seat as the rest of the range, but a different way of moving. It suits desk work where people recline through the day rather than sitting bolt upright: private offices, management workstations and meeting-adjacent spaces.
The difference is the Management Synchro (-1) mechanism. Rather than setting seat and back angle separately, the seat and back tilt together in a fixed ratio, so the sitter's hips and torso open up as one and the feet stay planted. A tension knob matches the resistance to body weight, and the tilt locks in three positions, enough choice to be useful, few enough that people actually set it once and get on with their work.
