Chadwick® High Task Chair

Smart. Comfortable. Easy. Accessible. Just Right.

Don Chadwick, a pioneer of ergonomic design, created a chair that marries the best of his thinking with the finest principles of Knoll design. From its streamlined form to its smart engineering, Chadwick is the office chair refined — and redefined. It responds to your body’s movements throughout the day with energizing comfort and a supportive ride.

Active Suspension

Active Suspension™ couples two unique features:

Synchronized Recline allows the user’s torso to open up, promoting health circulation and creating a ride that keeps the user’s back in contact with the chair.

Proprietary Suspension Fabric provides energizing support all day long, conforming to the user’s shape and minimizing pressure points. The open weave provides aeration.

Variable Seat Depth

The seat area automatically expands 2.5" from (16.9" to 19.4") when sitting in the chair. This is a function of the recline geometry, which helps accommodate a large range of users.

Built-in Forward Tilt

Built-in Forward Tilt automatically follows and supports users in forward and perching postures without adjustment. Optional Tilt Stop engages upright tilt limiter for less recline.

Lumbar Support

Chadwick features ample lumbar curvature and tension in the back suspension area. For users who require additional lumbar support, an optional lumbar attachment is available.

Straightforward Controls

Chadwick adjustments don't have to be learned. Minimal controls allow the user to adjust the chair to his or her body instantly with only a couple of effortless adjustments. Tilt Tension and Seat Height are standard controls, Tilt Stop is optional.

One of the world’s foremost experts in ergonomics, Don Chadwick received his principal design training at the University of California, Los Angeles. He then worked for architect Victor Gruen before establishing his own practice in 1964.

Over the last several decades, Don Chadwick has pioneered the use of modern materials, molding processes, and mechanisms to revolutionize the field of ergonomic chair design. In 1994, Chadwick designed the landmark Aeron Chair for Herman Miller, catapulting him to national attention.

In collaboration with Knoll, Chadwick applied his expertise to develop the Chadwick Chair in 2005. He returned to Knoll in 2009 to introduce the Spark Series. Knoll Design Director, Benjamin Pardo said of the Spark: "Don worked within the architectural constraints of the chair without adding unnecessary embellishments or sacrificing comfort. Spark's subtle design allows it to change personality through color, texture and pattern. This subtlety brings an enduring quality to the design that is consistent with our modern design heritage at Knoll."
