Concise guidance on fit, adjustment, measurement, and the questions worth asking before choosing equipment.
A useful chair is one whose adjustment ranges suit the user and task. Check seat height and depth, back support, armrest movement, control usability, and the clearances around the desk. More adjustments are not automatically better if they are inaccessible or poorly matched.
Workstation fit connects seat support, foot contact, work-surface height, input-device reach, display sightlines, and task duration. Adjust one element at a time, observe the effect, and preserve regular movement rather than searching for one fixed posture.
An inertial measurement unit commonly combines accelerometers and gyroscopes; some also include magnetometers. Selecting one requires attention to sampling, range, noise, drift, coordinate systems, synchronization, mounting, software, and access to raw data.
A well-made product can still be a poor match. Physical dimensions, adjustment ranges, controls, compatibility, the room, and the work itself determine whether equipment can support the intended user. Limitations are part of the decision, not fine print.
