There are several different types of chair arms that provide different levels of support, comfort, and adjustability. Here are some of the most common types:
Fixed arms: Fixed arms are attached to the chair and cannot be adjusted. They provide a basic level of support for the user's arms and are typically found on budget chairs.
Adjustable arms: Adjustable arms can be adjusted up or down to provide a custom fit for the user. They are typically found on mid-range to high-end chairs and provide improved comfort and support.
Width-adjustable arms: Width-adjustable arms can be adjusted to provide a custom fit for users with wider or narrower shoulders. They are typically found on high-end chairs and provide a high level of customization.
Overall, the type of chair arms you choose depends on your personal preference and the level of adjustability and comfort you need.
