Define the Intended Seating Assignment
Office chairs with fixed arms without lumbar support warrant a clear distinction between individual and shared use. For an assigned chair, assess the named person's usual workstation and tasks. For a shared arrangement, include representative users because the fixed arms remain in the same position for everyone. Do not assume that one person's preferred arm placement describes the needs of the group. Record the desks involved as well as the people. A chair that fits one arrangement may encounter different clearances elsewhere, and those differences need checking before conclusions are extended across a department or room.
Test Fixed Arm Geometry at the Desk
Begin with natural arm placement, then examine how the fixed rests relate to the worktop. Ask the person to reach the keyboard and pointing device without deliberately shifting into a demonstration pose. Note any contact between the arms and desk, and whether the chair stops farther away than the person would choose. Also test leaving the desk and approaching it again. The purpose is to understand the existing dimensions in use. Other adjustments, if present, should be checked individually rather than treated as a guaranteed remedy for an unsuitable armrest position or spacing.
Assess Backrest Fit Without Lumbar Support
When examining office chairs with fixed arms without lumbar support, focus on the back contact users actually experience. Ask where the backrest meets them, whether that contact remains useful during familiar tasks and what changes as they move. The absence of lumbar support does not describe the complete backrest shape or its available settings. Verify those details separately. Avoid adding an accessory during the initial comparison, because that would change the arrangement being assessed. First establish how the chair itself fits, then record any further requirement clearly as a separate workplace consideration for the manager.
