Inspired by the natural suppleness and beauty of a fern leaf, this office chair provides new levels of balance, flexibility, and performance. Designed in consultation with experts in biomechanics, physical therapy, and kinesiology, Fern evenly distributes weight as you move to relieve pressure. The patented Wave Suspension system mimics the human spine and cradles the body in comfort. Innovative 4D arms not only adjust in height but also move in multiple directions for customized support. Upholstered in a durable black textured fabric, the seat is complemented by a black airy mesh back that delivers firm support and naturally regulates body temperature by letting air pass through.
