Materials & Sustainability

  • Product Materials

    Liberty Ocean 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. Ocean plastic, including discarded fishing nets upcycled from ocean and coastal environments, is incorporated into select structural components.

  • Upcycled Ocean Plastic

    Select components in this product are made using up to 2 lbs of upcycled plastic from ocean and coastal environments, including discarded fishing nets. Each unit produced diverts material from marine ecosystems while delivering the same performance as virgin materials.

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.

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.

    Work at a sit

    I work at a sit-stand desk and the stool is perfect for brief seated work. Fabric feels cozy, mesh wouldn’t have been as nice in winter.

    Love the design and sustainability angle. Fabric is easy to clean, foot ring works great, and overall this is the most comfortable stool I’ve used.

    Comfortable and practical

    Comfortable and practical. Fabric back gives a soft feel but still provides good support. Adjusts easily when I move around, no levers needed, as advertised.
