Articulating the sophistication of European styling, along with the functionality of a multi-positional chair, this chair is sure to please. Mid-back office chairs are the logical choice for performing an array of tasks, offering 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 contoured seat dissipates pressure points for greater comfort. 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.
