Organise the trial around different users
For a shared workspace, identify representative users and give them a consistent set of activities to try. Ask each person to settle at the desk, work with normal equipment and change position as the role requires. Record their observations individually, including where they feel support and where they encounter unwanted contact.
Black base office chairs without headrests leave the seat and backrest arrangement central to this trial. Check available adjustments directly and note which settings each user needs. The stated combination does not confirm a particular mechanism, lumbar support or armrest configuration, so these features require separate verification before they enter the comparison.
Test clearance as part of desk use
Assess the seating with the workstation arranged as it normally operates. Include desk legs, storage units, cables and any equipment used near the feet. Measure the base footprint and check the space needed to sit down, approach the work surface and leave the seat without disturbing nearby furniture or other users.
Floor contact should also be reviewed directly. A black base description does not identify the components that touch the floor or establish their compatibility with a particular surface. Confirm the intended arrangement and include normal repositioning in the assessment where movement is part of the seating's documented use at the workplace.
