Materials & Sustainability

  • Product Materials

    Freedom Ocean is constructed using die-cast aluminum, steel, engineered polymers, contoured seat and back 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. 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 4.2 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

    Care instructions vary depending on the selected upholstery. Vacuum regularly using a soft brush attachment to remove dust and prevent dirt from working into the fibers. For spills, act quickly — blot liquids with an absorbent cloth before they set. Stains should be removed by gently dabbing with a lint-free cloth or sponge dampened with clean, warm water. If necessary, add a small amount of mild dish soap, then finish by dabbing with clean water. Avoid rubbing, as this may damage the textile surface. For wool textiles, professional dry cleaning is recommended for anything beyond surface stains. For detailed care instructions by upholstery type, refer to the Humanscale Care Guide.

  • Frame, Base & Components

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

The gold standard in office seating has been set by the Freedom chair by Humanscale.

Truly a grail chair... as much of a centerpiece for a home office as an Eames chair for a living room.

Sets a high standard for ergonomic seating.

Comfortable enough to sleep in.

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.

    I've been sitting on

    I’ve been sitting on this chair for about 3 weeks now. My lower back has never felt better. Arms move easily but sometimes slide down if I’m not careful. Still, worth it.

    Can fine-tune height

    I love the adjustability. Can fine-tune height, tilt, arm position. My back thanks me every day.

    Use mine in the lab

    I use mine in the lab. Moves around easily and keeps me comfortable during long experiments. Was worried the material would be hard to clean, but it’s perfect.

    Great chair overall

    Great chair overall. Took a bit to get the seat height right for my short legs. Feels sturdy and surprisingly comfy for long conference calls.

    Chair replaced a 15-year old model

    This chair replaced a 15-year old model. Felt like sitting on clouds compared to my old one. Highly recommend if you work from home.
