The catch
Herman Miller Aeron
A stiff seat rim makes cross-legged sitting awkward, and the wrong size can leave pressure points.
Side by side
If cooling, a floating recline and a mesh seat in the right size top your list, Aeron is the pick. Embody works better if you want a broader padded seat and shift your legs around often.

The catch
A stiff seat rim makes cross-legged sitting awkward, and the wrong size can leave pressure points.
The catch
Getting Backfit right takes patient adjustment. The exposed back structure may also make small noises when it moves.

Decide whether you want the cool, suspended mesh or the flexible upholstered seat.
This one comes down to seat and back feel first, then to the limits of your own setup.
Day to day
The Aeron selected here is Size B, so switching users leaves its seat depth where it is. On Embody the front of the seat moves to suit different thigh lengths. Pick Embody if two regular users need different depths that fall within its adjustment range. Pick Aeron only once both users fit the selected size, and don't assume its separate A and C versions can be reproduced with a lever.
Herman Miller gives the Size B seat depth as 17 inches. Embody lengthens its seat with two front handles. That is a difference in adjustment. It does not prove that either suits every user.
When adjustable lower-back support is why you want Aeron, check the real configuration instead of trusting the Size B and Mineral labels. Within the same family, Herman Miller sells different back-support packages. Embody has a documented Backfit control, which is a different and confirmed way to tune the curve of the backrest. Go with Aeron once the seller names the support option you need, or with Embody if that Backfit adjustment suits the job.
Aeron’s buying guide separates zonal support, adjustable lumbar and PostureFit options. The size and color in the catalog don't say which one is fitted. The point is to verify the package. We make no claim that the selected Aeron lacks adjustable support.
Which one fits
Herman Miller Aeron lists “8Z Pellicle mesh in three frame sizes” for seat, while Herman Miller Embody lists “Layered fabric seat with adjustable depth”. For seat, this affects body support and how well the adjustments suit you. A feature list cannot replace checking the comfort yourself.
Herman Miller Aeron lists “Firm, size-dependent and highly ventilated” for back feel, while Herman Miller Embody lists “Flexible with a tunable Backfit curve”. For back feel, this affects body support and how well the adjustments suit you. A feature list cannot replace checking the comfort yourself.
Coverage from the manufacturer is unusually long, within the stated limits on user, shift and upholstery.
A mesh or open suspension back lets more air through than a backrest that is fully upholstered.
The seat, back support and controls cope well with long sessions if you pair them with regular movement breaks.
The backrest or padded lumbar system touches the lower back over a broader area, with less of a pointed feel.

Herman Miller, Size B, Mineral
This all-mesh task chair is the benchmark of its kind. It comes in three body sizes, tilts exceptionally smoothly and gives firm support inside its frame.

Herman Miller, Charcoal Rhythm
Backfit control, a narrow back and a depth-adjustable seat make this flexible upholstered chair a good match if you change posture often.
