Read The Desk And Chair As One Arrangement
Begin with the working surface, equipment positions and the user's normal approach to the desk. Armless office chairs with fixed-height backrests have no chair arms to assess, so establish where forearm support comes from during typing, reading and pauses. Ask the person to move through those activities without rearranging everything for the demonstration. Note whether reaching changes their contact with the backrest. The objective is to understand how the complete workstation supports the task, rather than treating the chair as an isolated object whose suitability can be judged away from the working environment.
Check Back Contact Before Wider Allocation
Because backrest height cannot be changed, its existing vertical position needs direct assessment with each intended user. Ask where contact occurs and whether that contact remains useful when the person settles into an ordinary working position. If a mismatch appears, record it clearly. Do not assume another adjustment is available or that changing an unrelated setting will resolve it. Office chairs used across a team need a broader trial than a single person's initial impression, particularly where several colleagues will rotate through the same desks and cannot alter backrest height between their individual sessions.
