Adjustable height, width, depth and swivel (4D) armrests provide the highest level of customization and ergonomic support for office chair users. Here are some key features and benefits of 4D armrests:

1. Height adjustment : As with other adjustable armrests, 4D armrests can be adjusted in height to find the optimal position for the arms, reducing tension in the shoulders and neck.
2. Width adjustment : In addition to height adjustment, 4D armrests can also be adjusted in width, allowing users to adjust the distance between the armrests according to the width of their body for comfortable support.
3. Depth adjustment : A unique feature of 4D armrests is the depth adjustment, which allows users to adjust the distance between the armrests and the desktop. This provides optimal support for the forearms and prevents the arms from moving too far from the desktop.
4. Swivel Covers : The swivel aspect of the armrests allows users to rotate the covers in or out, allowing them to position their arms closer to the keyboard while typing. This reduces strain on the shoulders and promotes a more relaxed and natural typing position.
5. Flexibility and comfort : Through the combination of height, width, depth and swivel adjustment, Adjustable armrests in height, width, depth and swivel (4D) offer an unparalleled degree of flexibility and comfort. This makes them ideal for users who do long-term desk work and strive for the most comfortable support for their arms and shoulders.
6. Ultimate ergonomics : The use of office chairs with 4D armrests in combination with a height-adjustable desk ensures an optimal ergonomic workplace. Users can adjust their chair to their individual needs and preferences, allowing them to work comfortably without being exposed to excessive strain or fatigue.

In short, adjustable 4D armrests offer a comprehensive range of adjustment options that ensure optimal ergonomic support and comfort for users during long periods of sitting. This contributes to a healthy and productive working environment.
