Herman Miller Mirra 2 and Mirra are both made for long desk days. I like both chairs for a home office, but they do not feel the same. The Mirra 2 feels more refined and gives me more ways to set the seat. The older Mirra has a simple feel that many users still enjoy. I looked at the back, seat, fit, tilt, and daily use of both chairs. For most US buyers, I would lean toward the Mirra 2 if the price fits the budget. In short, Mirra 2 is the better all-around pick, while Mirra can be a smart used-chair buy.
Herman Miller Mirra 2 Review
The Herman Miller Mirra 2 is a great office chair for people who like to move while they work. I like how the chair follows my body when I lean, reach, or change my sitting pose. The seat can adjust from about 16.2 to 18 inches in depth, which helps me find a better fit. I also like the choice of a TriFlex back or a softer Butterfly back. For long typing work, reading, and desk calls, the Mirra 2 gives me a firm but active feel. Its tilt system also makes leaning back feel smooth and easy. If I wanted one Mirra chair for daily home office use, this is the one I would choose.
Pros
- Flexible seat: I like that I can change the seat depth to better match my leg length.
- Moving back: The back gives me room to shift instead of forcing one fixed sitting pose.
- Good fit range: The height and seat depth controls make it easier for me to find a useful setup.
- Breathable design: I found the open back style helpful during long work hours.
- Strong build: The chair feels made for years of regular office use.
Cons
- High price: A new Mirra 2 can cost a lot, so I would compare the price with a good used model.
- Firm seat: I would not pick it if I wanted a soft, deep cushion like a padded executive chair.
- One main size: Buyers with very different body shapes should try the chair before making a big purchase.
Herman Miller Mirra 2 Overview
| Feature | Details |
|---|---|
| Power | Not powered; manual office chair |
| Size | About 41.8–43.8″H × 26.5–31″W × 26.5″D |
| Material | Flexible polymer or suspension back, mesh seat, strong plastic parts |
| Weight | About 35 lb, depending on setup |
| Cleaning | Wipe the hard parts with a soft cloth; follow fabric care rules |
| Warranty | 12 years on new eligible purchases |
The Mirra 2 has several setup choices. The back can be a TriFlex polymer style or a Butterfly suspension style. The seat depth can also be adjusted on supported versions. Seat height can range from about 14.8 to 22.2 inches, based on the chair setup. The chair is also rated for users up to about 350 pounds.
Is the Herman Miller Mirra 2 Good?
Yes, I think the Mirra 2 is a very good office chair for daily desk work. I like it most when I spend many hours typing, reading, and switching between tasks. The moving back helps when I do not want to stay in one pose all day. The seat also gives me a useful range for finding a better leg position.
I would pick the Butterfly back if I wanted a softer and more giving back feel. The TriFlex back makes more sense if I want a firm and open feel. I also like the forward tilt option for times when I lean toward my desk while typing or writing.
The main thing I would check is fit. The Mirra 2 is not a soft lounge chair, and its seat may feel firm at first. I would also check the exact setup before buying because arm, back, and seat options can change the feel of the chair.
For a US home office, I see the Mirra 2 as a long-term chair rather than a quick low-cost buy. If I planned to sit at the same desk most days, I would be willing to spend more for the right setup.
My Recommendation
I recommend the Mirra 2 to people who want an active office chair with many useful adjustments. I think it works best for remote workers, writers, gamers, and anyone who sits at a desk for long hours. I would tell budget buyers to look at a clean used Mirra 2 before paying full new-chair cost. If you want a softer seat or a more padded feel, I would test other chairs first. For my own pick in the Mirra line, I would choose the Mirra 2.
Knoll ReGeneration Review
The Knoll ReGeneration is a good pick for me when I want a chair that lets me move while I work. Its back feels flexible instead of stiff. I can lean, shift, and change my sitting pose without feeling locked in one spot. I like this most when I switch between typing, reading, and looking at papers. The seat also gives me a roomy place to sit during long desk work. In the Herman Miller Sayl vs Knoll Regeneration match, the ReGeneration stands out most for easy body movement.
Pros
- Flexible back: I liked how the back moved with me when I leaned or changed my sitting pose.
- Roomy seat: The wider seat gave me more space to move without feeling tight.

- Simple controls: The chair did not take much time for me to learn.
- Long-term build: I like the 12-year warranty for a chair that I plan to use for years.
Cons
- Weight limit: The chair supports up to 300 pounds, so I would check this before buying.
- Needs more room: Its wider shape may not fit well beside a small desk.
- Different back feel: The flexible back may take some time to feel normal if I am used to a firm office chair.

Is the Knoll ReGeneration Good?
Yes, I think the Knoll ReGeneration is good for people who like to move while they work. I found it useful when I changed from typing to reading or turned to reach something near me. The flexible back made these small moves feel easy. The wider seat also gave me more room than a tight office chair. I would not choose it only because of its looks.
