Product Description

Liberty, with Form-Sensing Mesh Technology, 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. Choose with or without arms.

The Designer

One of the century’s pre-eminent designers, Niels Diffrient has endeavoured throughout his career to emphasise the “human factors” of industrial design, using ingenuity and intuition to provide consumer products that meet their needs. His emphasis on meeting human needs was codified in the three volume Humanscale, an influential sourcebook for designers that examined the movements and dimensions of the human body.

His quest to create workplace environments fitted to the needs of their users; continues unabated with “Liberty,” a task chair that conforms to its user’s shape without an array of knobs and levers. Movement is essential for a healthy back. People are spending more time sitting than ever before.

Not surprisingly, this increase in sitting has been accompanied by a proportional increase in back problems. Our bodies were designed to move. In fact, movement, more than anything else, provides nourishment for the spine, keeps the joints lubricated and flexible, improves circulation and therefore keeps us comfortable. Conversely, when we don’t move, the elasticity of our spine and joints is reduced and our muscles become fatigued. The key to healthy and comfortable sitting is being able to move without restrictions.
