Mid-back work chair offers a supportive mesh back and a fabric seat for responsive seating. Fixed position T-arms provide straight-forward support for forearms in nondemanding applications. Distance between arms measures 17", and the height from theseat is 8-7/8". Functions include 360-degree swivel, pneumatic seat-height adjustment from 19" to 22-5/8", dual-action synchro tilt, tilt tension, and tilt lock. Synchro-tilt allows the back to recline twice as fast as the seat. As the back reclines, the seat remains relatively level, promoting leg circulation and ergonomic function. Tilt tension adjusts the amount of resistance when reclining to accommodate individual weight and work styles. Tilt lock secures the chair in an upright position for constant back support when not reclining. Five-star base features 2-1/2" diameter dual black wheels and injection-molded plastic. Arms are also made with black injection-molded plastic and built-in polyurethane arms pad for comfort.
