The Design Story

Niels Diffrient designed the Liberty chair based on his idea for a fully functional, yet minimal, mesh task chair. The Liberty has curved lines and a contemporary look and feel. The features of the Liberty chair include an innovative tri-panel non-stretch mesh backrest, which he based on the concept of a tailored men’s shirt. Working closely with textile designer Elizabeth Whelan, the end result is a mesh that is a flexible, as well as strong and supportive.

"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."

Seat Fabric

Fourtis - Grade 1

Inspired by the Latin word fortis, meaning strong, this fabric is the ultimate ratio of durability and flexibility thanks to a unique weave of two-blended colors, and offering a four-way stretch.

Corde 4 - Grade 1

Constructed from cotton, Corde 4 includes a four-way stretch and a small, modular weave. The result is a dimensionally ribbed surface on the face of the fabric that remains soft to the touch.

Lotus - Grade 1

This four-way stretch textile is water repellant and easy to clean, making it an ideal textile for healthcare and hospitality environments. Its polyurethane finish with nylon backing boasts a soft texture while offering exceptional durability. It exceeds all standards for contract upholstery and healthcare tests.

Sensuede - Grade 3

Sensuede was developed to be the best and most luxurious engineered suede available. The faux suede's soft touch comes from the use of breathable and wrinkle resistant recycled microfibers that are finer than a human hair but are extra-strong, resulting in a very resilient fabric. This material also was selected because of its environmentally sensitive content and manufacturing process.

Ticino Leather - Grade 1

Ticino is a semi-aniline dyed leather available in a variety of rich colors inspired by nature. It is a top, corrected grain leather to create a more natural aesthetic and ensure the leather remains as unique as the hide itself.

Corvara Leather - Grade 3

Corvara is a semi-aniline dyed leather that offers a smooth, silky feel and ultimate durability. It is a top, full grain leather that is embossed lightly for a consistent, uniform grain structure.


Box Stitching Color

Choose from a variety of different color box stitchings for your chair. This option is only available for leather upholstery.

Seat Cushion

The Liberty's thin seat cushion is designed specifically for long-term sitting comfort, whether with the double foam seat or the optional Technogel cushion that maximizes weight distribution and comfort. Both seats are very comfortable, but the gel seat upgrade offers better long-term support and relief of pressure points for users that sit in their chair 8 to 10 hours a day.

  • Standard foam seat is contoured to fit your body and reduce pressure points, and is both comfortable and supportive
  • Technogel seat cushion is a non-degradable, non-compressible Technogel layer on top of a foam core that provides maximum pressure distribution and offers unmatched, long-term comfort
  • Technogel seat is available only with the Lotus and Vellum fabrics and is not available with leather or Sensuede

Please Note: Technogel has a firmer "sit" than the standard foam that softens up somewhat after a few minutes and will offer better back support if you are seated for long periods of time. Users who are up and down more may prefer the foam.

Humanscale Freedom Chair Seat Cushion

Seat Height

The Humanscale Liberty Chair is available in your choice of four cylinder heights. Seat heights are measured from the floor to the compressed front center of the seat cushion:

Standard 16'' - 21'' H
Low 15.25'' - 19.5'' H
Tall 17'' - 22.25'' H
Return to height 17.7'' - 19.9'' H


The Humanscale Liberty Chair is available with your choice of standard casters, soft casters for hard floors, or stationary glides.

Standard Hard Casters 2 1/2'' double-wheeled for carpeted floors
Soft Casters 2 1/2'' soft double-wheeled for hard floors
Glides Non-rolling glides for fixed location use

    The chair is good. Our secretary likes it better than I do but I like mine more than hers.

    Humanscale Liberty Chair

    Posted by BD on Apr 25th 2013

    Love everything about it. I originally intended to buy a Herman Miller Aeron chair, but this was SO much more comfortable. The price through The Human Solution was excellent, I saved hundreds of dollars compared to the price at a competitor's showroom, where I originally sat in the chair. No complaints with the chair or with Human Solution.

    Liberty Chair

    Posted by Cathy Vee on Jul 29th 2011

    I purchased 50+ of these chairs for conference room/training room seating. They tend to "disappear" into private offices because folks find them so comfortable. Overall, a very good chair for the money -- good to look at too!

    Love the back rest on this chair

    Posted by Jenny A on Feb 25th 2011

    This chair fits me perfectly especially around the back when I lean back in my chair. The mesh material is flexible and really comfy. The chair looks great and I'm satisfied. The only request is a headrest model, I don't think I'd use a headrest but it would be nice to have an option to attach one.

    Happy Back, Happy Behind

    Posted by Anon A. Mouse on May 28th 2010

    I originally ordered the chair with a regular foam seat, which ended up being too hard for me and I ordered a replacement gel seat. The gel seat is much better. I like the adjustable arms so they fit under my desk without bumping. I got the short piston, as I'm 5'1", but it really is not that much lower than the regular. Excellent customer service from one person, not so good from another.

    Great Chair

    Posted by Patricia on Mar 22nd 2010

    I bought this chair from the Human solution. It arrived in perfect condition, takes literally 30 seconds to put together (a selling point in my book) and is so comfortable I hate getting up. Worth every, single penny. And, "Bridget strip Carmine" with black monofiliment mesh is gorgeous.

    My butt has never been more comfortable. Although expensive, I should have made this purchase a long time ago.
