Niels Diffrient, the designer of all of the Humanscale seating, is an icon in the industry and has led the way in designing chairs with Passive Ergonomics. He strives for simplicity of design and simplicity of use, so that the user sets some adjustments, in this case seat depth and back height, and afterward the chair simply moves with the person sitting in it. With Form-Sensing Mesh Technology, Liberty 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. The Liberty Chair comes with fixed height arms, which we only recommend for conference seating, or height adjustable arms that drop down far enough to be out of the way when you don't want them.

Our recommendation: The gel seat has a firmer "sit" that takes a few minutes to warm up and get soft. If you sit all day and have back problems, you'll likely love it. If you are up and down more, you may prefer the standard foam cushioning.
The standard cylinder on the Liberty fits most of our users, but taller and shorter individuals might want to opt for the tall or short cylinder to make sure their legs get the support they need. Drafting chairs configurations are also available for high chairs with a foot ring.
