What is the difference between Aeron B and C?

Here’s how the difference between the Aeron Size A, B, and C looks like at a glance

Thanks to its different sizes, the Herman Miller Aeron can cater to a variety of body types to better provide the posture and lumbar support that users need. The Aeron chairs are designed so that when you’re sitting, your body is positioned in an optimal way to best support the spine and hips. Choosing the wrong size for your height and weight may defeat the Aeron’s purpose. 

The Aeron Size B casts the widest net among the three sizes as it can fit more body types than size A and size C. In a nutshell, if you’re tall but tend to be on the lighter side, size B will most likely fit you best. Size B is good for users who weigh 125lbs to 325lbs, while size C is better for those who weigh 295 to 350 lbs. Another quick way to figure out whether to get size B or C is to compare your shoulder width to their backrest’s width. The Aeron Size B’s backrest measures 27″ wide while size C measures 28.25″.

Its mesh material is breathable and keeps you cool even when seated for extended periods. In addition, its armrests are plush and well-cushioned. 

The Aeron is equipped with five sets of dual wheel casters that glide smoothly on floors. It’s typically installed with standard caster wheels that work best on carpets, but they can be configured to be installed with the ones for hard floors as well. Apart from its unrivaled ergonomic features, what makes the Herman Miller Aeron worth every penny is its durability.
