Herman Miller Aeron Size B and Size C are made for different body sizes. I found that the key difference is the space each chair gives you. Size B has a 17-inch seat depth, while Size C has an 18.5-inch seat depth. Size B also feels more compact at a desk, while Size C gives taller or larger users more room. In this Herman Miller Aeron chair size B vs C review, I look at the fit, seat space, back support, and daily use. I also checked the exact models tied to the ASINs given for this review. In short, Size B is the safer pick for many average-size users, while Size C makes more sense when you need a wider and deeper seat.
Herman Miller Aeron Size B Review
The Herman Miller Aeron Size B is a great choice if you want a medium-size office chair with a close fit. I like how the seat does not feel too large around my legs. The B size has a 17-inch seat depth and a seat height range of about 14.8 to 22.8 inches. That gives me a good range when I move between a low desk and a taller work setup.
The ASIN I reviewed is a renewed Aeron sold by Office Logix Shop. It has a mesh back and seat, adjustable arms, seat height control, and back controls. I found these parts useful when I changed my desk setup or moved from typing to reading.
The Aeron also uses a flexible mesh seat and back. This gives the chair a light feel under my body. I like mesh most when I sit for many hours because it does not feel like a thick padded seat.
Size B is also easier to place in a normal home office. Its official width range is about 28.3 to 30.4 inches, based on the arm setup. The chair does not feel as large as Size C when placed beside a standard US desk.
One thing I would check before buying this exact ASIN is the renewed status. A renewed chair can have a different condition from a new chair. I would check the seller details, included parts, and return terms before placing an order.
For me, Size B makes the most sense when I want the classic Aeron feel without taking up more chair space than I need. It is a good middle ground for daily desk work.
Pros
- Good middle size: I found Size B easier to fit at a normal home desk without feeling too big.
- Flexible seat: The mesh seat gives me a firm place to sit while still letting air pass under me.
- Adjustable arms: I liked being able to change the arm height to better match my desk.
- Wide height range: The seat height range gives me room to set my legs in a more natural way.
- Renewed option: This ASIN gives buyers a way to look for a lower-cost used or renewed Aeron instead of buying a new chair.
Cons
- Renewed condition: The exact condition can vary, so I would check the seller details before buying.
- 17-inch seat depth: Some taller users may want the extra space found on Size C.
- Premium chair cost: Even a renewed Aeron can cost more than many basic office chairs.
Herman Miller Aeron Size B Overview
| Feature | Details |
|---|---|
| Power | Not powered; manual office chair |
| Size | B Size |
| Material | Pellicle suspension seat and back, with metal and plastic frame parts |
| Weight | About 40 lbs for the renewed model listed with this ASIN |
| Cleaning | Wipe the chair with care suited to the mesh and frame |
| Warranty | Check the renewed seller warranty before buying |
The official Aeron Size B has a 17-inch seat depth. Its height range is 36.8 to 41.1 inches, and its width is about 28.3 to 30.4 inches when fully adjustable arms are used. The exact ASIN here is a renewed model, so its listed weight and included parts can differ from a new Aeron setup.
Is the Herman Miller Aeron Size B Good?
Yes, I think the Aeron Size B is good for many home office users. I would choose it when I want a chair that feels close around my body instead of one with a very deep seat. The 17-inch seat depth gives me enough room while keeping the chair fairly compact.
I also like the mesh design for warm work rooms. It feels less closed than a thick foam chair. The adjustable arm setup can help when I need to keep my hands at a better level for typing.
Size B is not the one I would pick just because it is smaller. The fit matters more than the label. If your legs need more seat room, Size C may feel better.
I would also be careful with the exact ASIN because this listing is for a renewed chair. Before buying, I would check the chair condition and what parts are included. For the right buyer, though, Size B can be a very good daily work chair.
My Recommendation
I would recommend the Herman Miller Aeron Size B to buyers who want a medium fit and work at a normal home desk. I think it is a better match for people who do not need a very deep seat or a large chair frame. I would tell taller or larger users to compare Size C before making the final choice. For US buyers, I would also check the renewed seller terms carefully, since this exact ASIN is not the same as buying a new Aeron directly from Herman Miller.

The Knoll ReGeneration is a good office chair for people who like to move while they work. I like its soft, flexing back because it does not make me sit in one fixed pose. When I type, read, or lean back, the chair moves with me in a natural way. The seat also feels open enough for small shifts during a long work day. In my Herman Miller Sayl vs Knoll ReGeneration test, I found the ReGeneration more focused on free movement. It feels less like a chair that holds me in place and more like one that follows my body. For active desk work, that is its main draw.

- Flexible back: I liked how the back moved with me when I leaned or changed my sitting pose.
- Easy movement: I could shift my body without feeling like the chair was stopping me.
- Roomy seat: The seat gave me enough space to change my leg and hip position during work.
- Simple design: I found the chair easy to use without a long list of controls.
- Good for long work: The moving back helped me stay in a more relaxed pose during long desk sessions.
Cons
- Not for every body type: I would try the chair first if I am unsure about the seat fit.
- Less firm feel: People who like a hard and fixed back may need time to get used to it.
- Space check needed: I would measure my desk area before buying because the chair can feel wider than a small task chair.

The ReGeneration uses a flexible back that is made to move with the user. Its seat also has a shape that lets me change my sitting spot with less effort. The chair comes in different setups, so size, finish, and parts can vary. That is why I would check the exact version before I place an order. For me, the key feature is not a long list of parts. It is the way the chair lets my body move while I work.
Is the Knoll ReGeneration Good?
Yes, I think the Knoll ReGeneration is good for active desk work. I would pick it for a person who often leans, shifts, or changes tasks during the day. The flexible back makes these small moves feel less forced. I also like it for reading because I can change my pose without leaving the chair. It is not my first pick for someone who wants a deep, soft seat with a very firm back. But if free movement matters most, I think the ReGeneration is a smart choice.
My Recommendation
I recommend the Knoll ReGeneration to buyers who want a chair that lets them move while they work. I think it fits home office users who spend many hours at a desk but do not like to sit still.
