Liberty, with Form-Sensing Mesh Technology, is unlike any mesh chair you’ve seen or experienced. With its tri-panel construction, it has the body-fitting contours that single-panel stretch mesh chairs simply can’t achieve. And it offers perfect lumbar support for everyone, without external devices or manual adjustments. Liberty’s mesh back is formed by combining three panels of non-stretch mesh in the same way a tailor combines multiple pieces of material to form a shirt. Its contours are custom-made to both fit and support the human body in unprecedented comfort.
