How to choose an office chair
The four decisions that determine whether a chair works for you, and the specifications that answer each one.
Most chair specifications do not matter. Four decisions do, and each has a specification that answers it.
Does the lumbar support adjust, and on how many axes
A fixed contour is a guess at the average back. Height adjustment fits the curve to your spine; depth adjustment sets how firmly it pushes. Two axes is meaningfully better than one, and one is meaningfully better than none.
Can the seat depth be set
A seat pan that is too long presses behind the knee; too short and it carries no thigh. Look for a slider, and treat its absence as the reason a cheaper chair is cheaper.
How far do the armrests move
Armrests exist to take the weight of your arms off your shoulders. Fixed arms do that only if they happen to land at the right height. 3D and 4D arms adjust in enough directions to be set rather than tolerated.
What happens after four hours
Thick padding reads as comfortable in a showroom and compresses by the afternoon. Breathability, even tension and a recline you can actually lock matter more across a working day than first-sitting softness does.
What we cannot tell you
Fit is personal, and no specification captures it. These guides narrow the field to chairs whose support is real and documented; the last step is still sitting in one.
