One of our greatest ergonomic innovations is Dynamic Variable Lumbar (DVL)® support — and it’s automatic with every sit. DVL® support intuitively adjusts to your body every time you move. Responding to your weight, height, position, and the amount of pressure you place on it, our DVL pivots with you to keep you comfortable and supported even as you change positions. That way, you’re always focused on your work, not your back.
