Materials & Sustainability

  • Product Materials

    Liberty is constructed using die-cast aluminum, steel, engineered polymers, contoured seat cushion, multi-layer Duron arm pads, and upholstery textile. Die-cast aluminum and steel form the structural frame and recline mechanism. Engineered polymers are used for components requiring flexibility and impact resistance. The back features patented Form Sensing tri-panel fabric that takes on the exact shape of the sitter's back, providing a personalized fit and maximum adaptability.


Who It's For

- Ideal for home offices where you want the chair to blend seamlessly with your furniture

- Great for cooler rooms and workspaces where fabric adds a warmer, more comfortable finish

Care, Maintenance & Longevity

  • Upholstery

    Vacuum regularly using a soft brush attachment. For deeper cleaning, wipe down with a damp cloth — no soap required for routine maintenance. For stubborn marks, a small amount of mild soap solution can be applied and wiped clean with a damp cloth. Allow to dry fully before use.

  • Frame, Base & Components

    Clean metal and plastic components with a soft, damp cloth and mild soap if needed. Dry thoroughly.

A world-class ergonomic task chair with minimalist charms, this office chair projects versatility in both style and function.

The ergonomic designs are not just made for comfort, but also with the hope that they reduce the industry's footprint and use of potentially-harmful chemicals.

This chair looks as good as it feels, with sharp aesthetics centered around lined, tri-panel mesh.

Design By Niels Diffrient (1928–2013)

Niels Diffrient was a pioneering industrial designer known for his human-centered approach and belief that design should be intuitive and effortless. Often called “the last of the mid-century modernists,” he focused on simplicity, allowing form to follow function in its purest sense. A Cranbrook Academy graduate alongside Charles and Ray Eames and Eero Saarinen, Diffrient went on to shape some of the most iconic products of the 20th century. His work at Henry Dreyfuss Associates helped define modern industrial design, while his research into human factors redefined how products support the body. His partnership with Humanscale introduced a new standard in seating, creating designs that automatically adapt to the user. Diffrient’s legacy lives on in products that are simple, timeless, and designed to improve the human experience.
