Ask Staff About Tasks Before Appearance
Introduce green base office chairs without headrests by explaining the work situations being assessed. Ask participants to identify their main desk activities, how often they change position and any support requirements that should shape the trial. Keep the initial discussion focused on what they need to do comfortably at the workstation. Then explain that the green base will also be reviewed within the room scheme. This order gives staff a clear way to separate practical observations from colour preferences. Record requirements in the user's own terms where possible, so that later comparisons remain connected to the activities that prompted each comment.
Use a Trial That Produces Specific Feedback
Give each participant time to locate and use the controls actually provided. Ask them to set up at a representative desk and carry out familiar work. Useful feedback describes an achievable position, a setting that is missing or a movement that feels restricted by the workstation arrangement. Office chairs should also be assessed alongside any equipment normally used, including foot supports where relevant. Avoid interpreting silence about a headrest as evidence that none is needed. Ask directly about head support after the task trial and record the response separately from comments about backrest contact, seat fit and access around the desk.
