How Does a Herman Miller Aeron Chair Help Posture?

Ergonomic Design Elements

The Herman Miller Aeron Chair, heralded for its innovation in ergonomics after its introduction in the mid-1990s, improves posture primarily by means of its proprietary PostureFit system. PostureFit refers to the system of design elements that control and support the lower back sections of the Aeron Chair. Each chair's PostureFit system can be adjusted in multiple dimensions to achieve a customized fit for each user. The personalized lower back support creates conditions in which the most comfortable sitting position is also the most posture-perfect and ergonomic.

The chair back and armrests on the Aeron chair are also wider than those of other office task chairs, providing greater support. The chair back is contoured and exceptionally high, providing comprehensive support even when reclining.

The front of the seat features what Herman Miller calls a "waterfall design," meaning that the seat slopes forward under the thighs and knees rather than abruptly dropping off. This reduces stress on the veins in the thighs and legs, helping to prevent cardiovascular problems.

Features That Promote Better Spine and Muscular Support

In addition to the ergonomic features discussed above, the Aeron Chair boasts other features that help reduce strain on the muscles and spine. A key feature is the chair's use of pellicle in place of traditional upholstery. Pellicle is a thin, flexible mesh that is stretched over the contoured frames of the seat and back. These thin panels conform to the unique shape of each user, vastly extending the length of sitting time that users can spend before experiencing discomfort or fatigue.

The system of moving parts in the chair also contribute to better spinal and muscular help. The pivot points can be adjusted for tension and all move smoothly and fluidly, eliminating any need for straining. The chair back and seat also move together to maintain ergonomic support regardless of the user's sitting position. This reduces stress in the long term when it comes to repetitive motions such as reaching for drawers and cabinets without standing or leaning back while talking on the phone.

Other Comfort-Enhancing Features

While not directly related to posture or ergonomics, there are other design features that make the chair more comfortable and, therefore, encourage users to spend more time with full ergonomic support. One of those design benefits is delivered by the pellicle seat panels. Since pellicle is a mesh, it allows for an unprecedented level of ventilation and moisture dissipation, providing users with a cool, comfortable and breathable sitting experience.

For users with special ergonomic needs, there are also many lumbar support accessories that have been designed specifically for the Aeron chair. These accessories create new dimensions of customization that may be important to users with chronic back pain or spinal injuries.
