Follow The Sequence Of Everyday Work
Assess unstandardised office chairs without armrests through a realistic sequence: approach the desk, begin the main task, reach for nearby items and leave the seat. This reveals how the chair interacts with the workspace over several movements. A brief stationary sit provides only part of that picture.
Ask users to follow their normal habits before suggesting changes. Record any obstruction, repeated repositioning or forward reach, then identify its source. The absence of arms removes one possible contact point, but other chair dimensions and the surrounding furniture can still influence how freely someone uses the space.
Locate Support At The Working Surface
Without chair arms, assess what happens to the forearms during keyboard work, writing and other activities. Check equipment placement and the desk edge together. Ask whether the person can carry out the task with relaxed shoulders, rather than assuming that an open chair automatically produces an appropriate working position.
Compare office chairs with the same initial workstation arrangement. If a participant changes the keyboard position or another element, record why and what difference it makes. This helps distinguish a seating issue from a workspace issue, and gives the manager a practical basis for planning any necessary changes.
