Map The Work Surfaces Before Assessing Seating
Begin with the desks, tables and other surfaces that define the intended working positions. Record their relevant dimensions and the activities performed at each one. Then position the chair where it will actually be used, rather than judging the seat height in an unrelated room. Compare office chairs against a consistent set of observations: access to the work surface, space for the legs and the person's contact with the floor. If the workstation itself can be adjusted, assess that possibility separately. Avoid assuming an adjustable desk is present or that it will resolve every mismatch between a fixed seat and its intended user.
Understand What Fixed Seat Height Establishes
Fixed-height office chairs without headrests remove seat-height changes from the setup process. They do not establish a single standard seat dimension, nor do they confirm the presence or absence of tilt, armrests or other features. Ask for the actual measurements needed for the room and verify any movements that matter to the task. Keep these findings distinct in the assessment record. Two chairs can share the same basic configuration while placing a person differently relative to the work surface. The useful comparison is therefore between their confirmed dimensions and observed fit, rather than between broad descriptions that leave those differences unexplored during selection.
