This chair is ideal for anyone who does a great deal of typing throughout the day and needs good back support. The locking back angle adjustment lever changes the angle of your torso to reduce disc pressure. The locking synchrony tilt control allows the chair's back and seat to recline at different rates, increasing the angle between your torso and thighs.
