The Humanscale Liberty mesh chair, with its unique Form-Sensing Mesh Technology, is unlike any mesh chair you’ve sat on before. Its Mesh back fits the contouring of the body via its tri-panel construction, and naturally offers perfect lumbar support for everyone, without external devices or manual adjustments. Liberty’s tri zone mesh back tailored like a shirt and is formed by combining three panels of non-stretch mesh. Its contours are tailor-made to both fit and support the human body in unprecedented comfort.
Humanscale Liberty Mesh Chair

















The Humanscale Liberty Mesh chair with form sensing Mesh back features a revolutionary counter-balance mechanism, based around movement. Your body weight automatically balances the force required to recline the chair. So the recline tension is always perfectly adjusted to let you move while keeping you fully supported in all positions. The Liberty Mesh chair features a breathable mesh back and a seat with built in seat slide to adjust the seat depth finished in Oxygen Black Fabric.
