Humanscale meet the highest environmental standards


The Liberty Task chair is an intelligent mesh task chair engineered to provide automatic lumbar support for every user, as well as offering simplicity and complete ease of use. Liberty was designed to offer a unique, minimal aesthetic and to provide custom comfort for every person who sits in it. Like Humanscale’s Diffrient Smart and Diffrient World chairs, Liberty uses Humanscale’s revolutionary Form-Sensing Mesh Technology and mechanism-free recline for perfect support and unprecedented comfort. 

With a minimal aesthetic that complements any space, the Liberty chair is the ideal seating solution for the modern work environment. With advanced features, including automatic, weight-sensitive recline, armrests that are attached to the back of the chair for constant support, and an innovative tri-panel mesh backrest, Liberty combines performance, simplicity, and beauty. With fewer parts than traditional task chairs, Liberty is a timeless and environmentally friendly design.


About the designer

As the pioneer of ergonomics, Niels Diffrient aimed to redefine the concept of the traditional task chair and instead design seating solutions that efficiently adapt to users, allowing them to move freely from posture to posture. Diffrient’s unique approach removed complexities found in other chairs, such as cumbersome recline levers and back tension dials. He realized that movement during recline took the pressure off the user’s body, and transferred it to the back of the chair. As a result, he developed the weight-sensitive, self-locking recline mechanism, definitively reinventing the features of modern task seating to be truly simple, beautiful, and functional.
