This chair has a frameless 3D Intelligent Suspension back that allows freedom of movement, while providing targeted back support and moving heat away from the body. The suspension is supported by a Y-tower and anchored at the bottom by the ArcSpan. The chair has an upholstered seat with foam padding and passive Posturefit back support. The Synchronous tilt provides continuous balance and lets the body recline naturally, pivoting at the ankles, knees, and hips. This color varies in colors of the seat upholstery, back, base, and frame.
