Haworth's Soji office chair offers customizable support to keep your body aligned and comfortable. Adjustable arm and seat height keep you in neutral alignment, while the waterfall seat edge takes pressure off legs and knees. The seat is upholstered in a durable wool-blend in charcoal that offers a beautiful blend of color, weave and texture. The airy mesh back in steel grey delivers firm support and naturally regulates body temperature by letting air pass through.
