Measure the user and workstation
Define chair fit from the person and deskA chair cannot be selected from height or a weight limit alone. Body proportions, desk and keyboard geometry, floor, work pattern, movement preference and a real sitting trial determine whether the adjustment range is useful.
01
Person
Record the measurements that affect fit
Measure lower-leg length with work shoes, thigh length, hip width, elbow height and the intended seated and reclined postures.
- Seat
- The feet need stable support while the seat edge avoids pressure behind the knees.
- Width
- Seat and arm spacing must fit without forcing the elbows or leaving the controls unreachable.
02
Desk
Map the complete workstation
Measure keyboard, pointing device, desk underside, monitor, footrest and arm clearance. A chair cannot repair a desk that is too high or a keyboard placed too far away.
- Arms
- Test whether the selected arms clear the desk and support the actual input position.
- Floor
- Choose casters or glides for the floor and confirm rolling resistance and stability.
03
Work
Describe movement and duration
Record concentrated typing, calls, drawing, reclining, forward work, shared users and how often posture changes.
- Trial
- Use the exact configured chair for a representative session rather than a short showroom sit.
- Boundary
- No adjustment count or ergonomic label guarantees comfort, posture, pain relief, productivity or a medical outcome.
