The Liberty Task chair is an intelligent mesh task chair engineered to provide automatic lumbar support for every user, as well 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, arm rests 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.

Effortless Recline

Liberty’s intelligent mechanism-free recline uses the laws of physics and the sitter’s weight to automatically provide the perfect amount of support through the full range of recline. Without manual controls to adjust, the user can change postures effortlessly throughout the day.

Custom Fit

Liberty’s mesh back is formed by combining three panels of non-stretch mesh material in the same way a tailor combines multiple pieces of fabric to create a shirt. Its contours are made to custom fit and support each individual sitter throughout the day.

Encourages Movement

Liberty was engineered to automatically adjust to whoever sits in it, instantly accommodating each user regardless of size and weight. Because it has no manual adjustments and features Humanscale’s weight-sensitive recline, the user can move easily and without restrictions.
