Humanscale's World office chair offers full performance with a chic, minimalist design that focuses on comfort and simplicity. Featuring a sculpted foam seat upholstered in faux leather, the chair uses one's own body weight to ease into a supportive recline. The tri-paneled mesh back takes on the exact shape of the sitter's back for custom support and comfort. Multi-surface caster wheels and adjustable-height arms add to the task chair's exceptional features.
