This multi-functional office chair will give you an edge on comfort with its design and adjusting capabilities. Chair is attractively designed with its two-tone mesh upholstery that is seamlessly outlined in the seat and back of the chair. High back office chairs have backs extending to the upper back for greater support. The high back design relieves tension in the lower back, preventing long term strain. The locking back angle adjustment lever changes the angle of your torso to reduce disc pressure. The locking synchro tilt control allows the chair's back and seat to recline at different rates, increasing the angle between your torso and thighs. Chair easily swivels 360 degrees to get the maximum use of your workspace without strain. The pneumatic adjustment lever will allow you to easily adjust the seat to your desired height. The adjustable armrests take the pressure off the shoulders and the neck, which minimizes the risk of pain.
