What to Check Before Choosing a Chair?
Seat Height
Your feet should sit flat on the floor, with knees close to a 90-degree angle.
Lumbar Support
The backrest should support your lower back without forcing an awkward posture. Look for support that moves as you recline, not a fixed pad that stays in one position.
Armrest Position
Armrests should help your shoulders relax, not push them upward. Multi-directional armrests make the biggest difference if you type, use a mouse, or switch between tasks often.
Recline Control
A good recline should feel stable and usable, not loose or decorative. Synchro-tilt recline - where the seat and back move together - is worth prioritising for long sessions.
