An armrest can be comfortable in isolation and inconvenient at the desk. It may strike the desktop before the chair is close enough for typing, or its pad may push the elbow away from the body. Evaluate the chair and desk together rather than treating the armrests as a separate premium feature.
Begin with the chair's seat height and back support adjusted for the user. Then lower or raise the armrests within their permitted range. The shoulders should remain relaxed; lifting them to reach high pads is not the goal. At the other extreme, pads that are too low may offer little useful support.
Check all the directions that matter
Height is only one adjustment. Width changes the distance between the pads, while fore-and-aft movement changes where the support meets the arm. Some pads also pivot. These features are useful only when their ranges fit the person and the work. A long list of adjustment names does not establish that fit.
Bring the chair toward the desk. Check the underside, drawer fronts and any projecting edge. If the armrests collide, see whether a suitable adjustment permits access without compromising the sitting position. Do not assume that lowering the seat is the answer; that may make the work surface too high.
The armrest shape can affect handwriting. A large pad may obstruct the elbow when turning toward a notebook, even if it works well for keyboard use. Test a few normal movements rather than judging only a straight-ahead sitting pose.
Compare the chair with and without support
Some users prefer armrests for pauses or certain tasks and move them out of the way for others. A chair designed with removable or flip-back arms may offer that option. Follow the manufacturer’s instructions and do not remove structural components or make unauthorized modifications.
For a shared desk, make sure the controls can be changed without tools if users need different settings. Pads that drift or rotate unexpectedly can be frustrating, so check that the mechanism holds its intended position. Report damage rather than compensating with tape or improvised wedges.
The useful question is not whether the chair has armrests. It is whether those armrests support the user's activity while allowing the rest of the workstation to fit. A simpler, well-matched arrangement can work better than a highly adjustable chair whose arms are always in the way.
