Best ergonomic chairs for plus-size users
This is one of the audiences generic office-chair guides serve worst: most comparisons assume an average weight range and barely mention real maximum capacity, or whether that capacity changes depending on the size chosen within the same model.
To choose safely, check three things: the certified weight capacity for your specific size (not the generic model figure), the actual seat width, and whether the frame and gas lift are engineered for that weight range or simply “hold up” without a specific manufacturer guarantee. Brands like Herman Miller, Kinnarps and Duorest document this fairly clearly on their largest sizes.
Below are several options with documented weight capacities above 330 lb (150 kg), ranging from more affordable picks to premium references.

FAQ
How do I know if a chair safely supports my weight?
Always check the maximum weight listed by the manufacturer for the specific size you're buying, not just the generic model figure: many chairs offer different sizes with very different weight capacities.
Is a wide seat the same thing as a plus-size chair?
Not necessarily. A wide seat helps comfort, but weight capacity also depends on the frame, the gas lift, and the recline mechanism, which need to be certified to safely support that weight.
Which brands offer dedicated high-capacity sizes?
Herman Miller (Aeron size C, up to 400 lb / 181 kg), Kinnarps (6000, up to 396 lb / 180 kg) and Duorest (Executive, up to 353 lb / 160 kg) are among the options with the clearest, best-documented capacity data per size.
