What is the role of casters in office chairs?

1. Provide adjustment for height

2. Enhance aesthetic appeal

3. Facilitate smooth, friction-free movement

4. Support upper body alignment

The correct answer is: Facilitate smooth, friction-free movement

Casters play a crucial role in facilitating smooth, friction-free movement of office chairs. They allow users to easily glide across different surfaces, promoting mobility and flexibility within the workspace. This movement is essential for enabling individuals to reach different areas of their desks or collaborate with colleagues without the need to stand up or struggle against resistance. While other aspects such as height adjustment and aesthetic appeal are important in the overall design and functionality of office furniture, the primary function of casters is to enhance the chair's ability to move effortlessly and efficiently, which is key to creating a comfortable and productive work environment.
