Evolution Of Office Chair Armrest Support Based On Ergonomic Research

Our heart has a question about the armrests of office chairs: Is the armrest of the office chair really useful? Is there a need to exist? When we work, we often put the whole arm on the table, rarely use the handrails, and the handrails are just furnishings. This is the majority of the voices. This issue combines Steelcase's ergonomic research to explain the correct opening of the office chair armrest.


The evolution of office chair armrests:

When the personal computer was just installed in the office in the 1980s, the armrest was just an accessory for the president's chair, and the setup was simple and unadjustable.

By the end of the 1980s, as the demand for computer work increased, the design of office chairs changed. In order to promote longer sitting time, the upper and lower armrests were adjustable. The design was designed to closely match the human elbows when sitting. The relaxed height, the calculated 7-11 inch height adjustment range still applies to the needs of most office workers.

In the 1990s, advanced ergonomic seats added handrails with adjustable width and angle. The width adjustment ensures that the support for the arms is close to the body, while the angle adjustment ensures further support for a range of arm positions. Coupled with the height adjustment feature, these features, especially the ability to move the armrest support inwardly to the edge of the seat, are even more critical, as it provides arms from arm to shoulder and regardless of the user's size. Natural support from wrist to elbow.

In the past 10 years, the armrests of some office chairs have been added with depth adjustment function. This is because the flat computer display replaces the traditional heavy display. In order to free up more valuable desktop space, users can push the display to the deepest part of the desktop. But it also caused the collision of the front end of the armrest with the desktop or the computer keyboard bracket, which not only affected the proper viewing distance of the screen, but also caused a squat sitting posture, bending forward or leaning forward, these sitting postures would cause the neck and Discomfort in the shoulders. The front and rear slidable armrests ensure that many users get closer to their work and help them maintain a healthier posture.

New discovery of armrest design

Steelcase's ergonomics researchers systematically analyzed the sitting posture of 2,000 employees from 11 countries on six continents. Based on other trends, researchers have discovered that new, smaller, touch-screen-based devices, such as smartphones and tablets, are changing the way the human body sits and the way employees handle work. This research has fully demonstrated that the diversity of postures employed by today's employees has far exceeded the range of existing seat armrest designs.

Providing an appropriate armrest height and increasing the width of the adjustment range provides support for the person using the phone and tablet, moving the device to the appropriate line of sight to avoid bending of the head and neck. In addition to providing a wider range of adjustments, ease of use is also an important consideration for office chair armrests.

Which office chair armrests are ergonomic?

1, Steelcase World Leap ergonomic chair


The Leap ergonomic chair supports four directions (front and rear) and angle adjustment without twisting the wrist and lifting the elbow so that the wrist, arms and shoulders are properly supported. On the left side of the handrail contact surface, there is a handrail adjustment manual, and on the right side is the adjustment instructions of other parts. The design is very intimate, and the upper and lower adjustment distance of the handrail is 9 cm.

2, Steelcase Century Think Engineering Chair


The height, width, width, rotation and depth of the Think ergonomic chair can be adjusted to provide customized support for the arm. The armrest support frame is made of recyclable nylon material, which is durable and durable. The contact surface is made of PU leather, which is soft and comfortable to touch.

3, Herman Miller Herman Miller new Areon ergonomic chair

The armrests of the new Aeron ergonomic chair can be adjusted from left to right and up and down, the adjustment switch is behind the seat back, and the armrest and the back of the chair are connected together. When the human body leans back, the armrest can be adjusted accordingly to suit the human body. The pressure of sitting posture.

Herman Miller's new Aeroon ergonomic chair has been introduced, and although it retains the unique contours of this classic seat, each design component has been upgraded to take comfort to a new level.
