A practical sequence for setting chair height, foot support, seat depth, backrest, armrests, recline, keyboard position, and monitor placement.
Start with the chair and feet
Sit fully back in the chair and adjust the seat height so the feet are supported. If matching a fixed-height desk requires a higher seat position, use a stable footrest rather than leaving the feet unsupported.
Keep enough room behind the knees to avoid pressure from the front edge of the seat. If the seat is too deep and cannot be adjusted, a different chair may be needed.
Set the backrest
Adjust the backrest or lumbar support so it contacts the lower back without creating a hard pressure point. The goal is comfortable support, not forcing one rigid posture.
Use recline and tilt tension so the chair moves with you and remains stable. Try small changes and reassess after working for several minutes.
Set the armrests and desk relationship
Adjust armrests so the shoulders can remain relaxed and the elbows can stay near the body. If armrests prevent the chair from approaching the desk, lower, shorten, move, or remove them if the design permits.
The keyboard and pointing device should be reachable without lifting the shoulders or reaching forward for long periods.
Finish with the screen and movement plan
Position the screen so the head can remain generally aligned with the torso. Laptop-only work often needs an external keyboard and pointing device when used for extended periods.
No chair setting eliminates the need to change posture. Build in brief movement, task changes, and standing or walking opportunities.
Questions to ask before deciding
- Does the published range fit the user and desk?
- Can the controls be reached and understood during normal work?
- Do armrests, base, and recline fit the room?
- What testing, warranty, parts, and return evidence is available?
- Can the chair be tried with realistic tasks?
