The primary difference between a size B and a size C Aeron Chair lies in their dimensions: size B is the standard model, while size C is the larger, plus-size version. These distinct sizes are designed to accommodate a wider range of body types, ensuring optimal ergonomic support and comfort for various users.
Understanding Aeron Chair Sizes
Herman Miller's Aeron Chair is renowned for its ergonomic design, and a key aspect of its customization is the availability of three distinct sizes: A, B, and C. This sizing system ensures that users can find a chair that fits their body proportions, which is crucial for maintaining good posture and reducing discomfort during long hours of sitting.
Size B: The Standard
The size B Aeron Chair is considered the standard size and is the most commonly sold model. It is designed to fit the widest range of users, typically those of average height and build.
- Target User: Individuals ranging from approximately 5'3" to 6'6" in height and weighing between 130 to 300 pounds.
- Dimensions: Offers a balanced seat width and depth, along with appropriate backrest height, for a broad segment of the adult population.
- Versatility: Its "standard" designation means it's often the safest choice when unsure of the exact user dimensions, or for shared workspaces.
Size C: The Plus-Size Model
The size C Aeron Chair is the plus-size model, specifically engineered to provide enhanced comfort and support for taller and heavier individuals. It features larger dimensions across the board compared to the B size.
- Target User: Individuals who are generally taller than 6'6" or weigh more than 300 pounds.
- Dimensions: Provides a wider and deeper seat pan, a taller backrest, and a more robust frame to accommodate larger body frames comfortably.
- Enhanced Support: Ensures that individuals with a larger build receive adequate support for their thighs, back, and shoulders, preventing pressure points and promoting proper spinal alignment.

Choosing the Right Size
Selecting the correct Aeron chair size is paramount for long-term comfort and ergonomic benefits. While size B is the standard, opting for size C (or even size A, the smallest, for petite users) based on your body dimensions can significantly improve your experience.
Consider the following when making your choice:
- Height and Weight: These are the primary determinants. Refer to Herman Miller's official sizing charts, which often provide more precise recommendations.
- Body Proportions: Even if you fall within the general height/weight range for a B, if you have particularly long legs or a long torso, a C might offer better support for those specific areas.
- Comfort and Fit: The most reliable way to choose is to sit in both sizes if possible. Pay attention to:
- Seat Depth: Ensure there are 2-4 fingers' width between the edge of the seat and the back of your knees.
- Armrest Height: Can you comfortably rest your forearms parallel to the floor?
- Back Support: Does the lumbar support align with the natural curve of your lower back?
- Headroom: For taller individuals, ensure the backrest provides adequate support up to your shoulders.
Choosing the right size ensures that the chair's ergonomic features, such as the PostureFit SL back support and Kinemat tilt, function as intended for your unique body, promoting health and productivity.
