If chairs were living, breathing animals, subject to the same ruthless laws of natural selection other creatures are, the iOO would represent a pinnacle of evolution — a sleek, powerful product of generations of development and refinement, and an obsession with perfection. It is adjustable, yet effortlessly simple. All of its controls have been integrated into a single mechanism. The iOO adapts, overcomes and excels. Available in all mesh seat and back or fabric seat with mesh back, in both black and white frames.
