A guide to headrest fit, recline mechanisms, tilt tension, lock positions, and posture variation.
Recline is about variation
A chair that supports controlled recline can make it easier to change posture during the day. The mechanism should feel stable and should not require excessive effort to move.
Tilt tension should be adjusted to the user, while locks should be used selectively rather than keeping the chair rigid all day.
Headrests are task dependent
A headrest may be useful during reading, calls, or reclined work. During upright typing, a poorly positioned headrest can contact the head too early or encourage a forward head position.
Check height, depth, angle, and whether the headrest can be removed if it does not fit.
Mechanism terms vary
Synchro-tilt, knee-tilt, centre-tilt, back-angle adjustment, and multi-function controls describe different relationships between seat and back movement. Compare diagrams and manuals rather than relying on marketing names alone.
A seat that rises sharply at the front during recline may reduce foot contact for some users.
Test the full range safely
Recline gradually with the chair on a stable surface. Do not exceed the stated use limits or use a chair with a loose, damaged, or unpredictable mechanism.
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?
