Ferris Office Chair
The Ferris office chair generally refers to the Do/More Chairs designed by William Ferris. It is an important representative in the development history of office chairs worldwide, driving innovation in both functionality and design.

Background and Designer
The true emergence of office chairs globally was in the 1970s when office settings gradually diversified, and people had higher demands for the functionality and comfort of office furniture. William Ferris keenly captured this need and designed the Do/More Chairs. This chair broke the limitations of traditional office chairs, providing office workers with a more convenient and comfortable user experience, becoming an important milestone in the history of office chair development.
Functional Changes
- Swivel Function: The Do/More Chairs feature a swivel function, which significantly enhances office flexibility. During work, people do not need to frequently get up and move the chair. By simply turning their bodies, they can easily communicate with those around them, access materials from different directions, or operate office equipment, greatly improving work efficiency.
- Caster Design: The addition of casters makes the movement of the office chair smoother and more convenient. Office workers can freely move around in a large office area without the need to carry the chair, reducing physical exertion. At the same time, it also makes the layout of the office space more flexible, allowing for adjustments according to different work needs at any time.
- Height Adjustment: The height adjustment function is another important innovation of the Do/More Chairs. Office workers of different heights can adjust the chair to a suitable height according to their own needs, maintaining a comfortable sitting posture and reducing physical fatigue and health problems caused by prolonged incorrect sitting postures, such as cervical and lumbar spine diseases.
Development Impact
After years of development, office chairs represented by the Do/More Chairs have undergone multiple changes and improvements in terms of swivel, caster, and height adjustment functions. The continuous optimization of these functions has made office chairs more in line with ergonomic principles, better meeting the diverse needs of office workers and becoming an indispensable piece of furniture in modern office environments.
