This multi-functional office chair will give you an edge on comfort with its design and adjusting capabilities. This chair features a comfortably padded seat and back with built-in lumbar support for long hour work days. A mid-back office chair offers support to the mid-to-upper back region. 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 synchro tilt control allows the chair's back and seat to recline at different rates, increasing the angle between your torso and thighs. The waterfall front seat edge removes pressure from the lower legs and improves circulation. 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.
