Adjustable armrests in height, width and depth (3D) are adjustable in height, width and depth. This means that the armrests have the same properties of 2D armrests, extended with covers or armrests (plastic or upholstered top on which your arm rests) that can be moved forward and backward. This can usually be done using a button located under the armrest. Because the armrest can be slid forward and back, you can lengthen or shorten the distance from your forearm to your desktop so that you can get closer or further from your keyboard and computer screen without having to lower your armrests. It also makes it easier for you to maintain the 90° rule of your elbow, which provides support for your forearm.

Adjustable armrests in height, width and depth (3D) are a crucial component of ergonomic office chairs, designed to provide optimal comfort and support during long working hours. Below we explain how these armrests function, why they are important for good ergonomics, and what you should pay attention to when choosing an office chair with 3D armrests.

How Do Adjustable 3D Armrests Work?

1. Height adjustment

• As with standard 2D armrests, you can adjust the height of 3D armrests. This ensures that users of different heights can adjust their armrests so that their shoulders remain relaxed, without being hunched up.

2. Width adjustment

• The width adjustment makes it possible to change the distance between the two armrests. This is especially useful for wider or narrower users, ensuring that the armrests are always at a comfortable width.

3. Depth adjustment

• The depth adjustment, which is a unique feature of Adjustable armrests in height, width and depth (3D), allows the armrests to be moved forward or backward. This makes it possible to optimize the distance from the forearm to the desktop, which is very important for accessing the keyboard or mouse without excessive strain on the elbows or shoulders.

Why Are 3D Armrests Important?

• Ergonomic Benefits : They allow the user to find a position that is natural and comfortable, which reduces pressure on the shoulders and neck.
• Flexibility : Their adaptability makes them ideal for workplaces used by multiple people, such as shared offices or flexible workspaces.
• Prevention of RSI : Through correct positioning of the arms, 3D armrests can help prevent repetitive stress injuries, which are common with prolonged typing or mouse use.

What do you have to pay attention to?

1. Quality of Mechanisms

• Choose a chair whose armrests are sturdy and easy to adjust. The mechanisms must be durable and able to withstand frequent use.

2. Material of the Armrests

• The top of the armrests should be comfortable. Options include soft plastic, upholstered surfaces or even gel cushions, depending on personal preference and comfort level.

3. Work Environment Compatibility

• Make sure that the chair with 3D armrests fits well with your desk height and work setup. This prevents the armrests from being too high or too low, which can undermine the ergonomic benefits.

4. Overall Ergonomics of the Chair

• While armrests are important, you should also consider other ergonomic features of the chair, such as lumbar support, seat depth and the ability to adjust the backrest.

Conclusion

Adjustable 3D armrests provide an advanced level of ergonomic adjustment that can help increase comfort and productivity in the workplace. When choosing an office chair with this feature, consider the build quality, the comfort of the armrests, and how well they integrate with your existing office setup. By investing in a chair that is well suited to your needs, you can enjoy improved ergonomics and comfort.
