Humanscale Liberty Chair

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. 

Humanscale Liberty Chair

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.

Liberty, with Form-Sensing Mesh Technology, is unlike any mesh chair you’ve seen or experienced. With its tri-panel construction, Liberty has the body-fitting contours that single-panel stretch mesh chairs simply can’t achieve. And it offers perfect lumbar support and balanced recline for everyone, without external devices or manual adjustments.

Design Story

"I’ve always insisted that the back adjust to the person and we have this unique Form Sensing Mesh that will accommodate any body shape and give you appropriate back support. Whether you’re short, tall, wide, narrow, the back will accommodate you."

Niels Diffrient, Designer

Inspired to create a minimal but functional mesh task chair with curved lines and a contemporary aesthetic, Niels Diffrient designed Liberty. As with the Diffrient World chair, Liberty features an innovative tri-panel non-stretch mesh backrest, which Diffrient said was based on the concept of a tailored men’s shirt. He worked closely with textile designer Elizabeth Whelan to create a mesh that was strong and supportive but still flexible.

More Information

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.
