If you are choosing between Herman Miller vs HBADA, I would first look at how you plan to use the chair. I tested the Herman Miller Mirra and the HBADA J1 to see how they feel at a desk. The Mirra is the more advanced chair, while the HBADA J1 is made for buyers who want to spend less. I liked the Mirra more for long work days because it gives me more ways to set the chair to my body. The HBADA J1 is much simpler and takes less effort to adjust. Both can work well in a US home office, but they suit very different needs. In short, the Mirra is my pick for long work, while the HBADA is the better low-cost choice.
Herman Miller Mirra Review
The Herman Miller Mirra is the chair I would pick when comfort and fit matter most. I like its firm seat and flexible back during long desk work. The chair has many ways to adjust the seat, arms, tilt, and back support. That made it easy for me to set a work spot that felt right.
The back has an open design that lets air move through. I found this nice when I sat at my desk for many hours. The seat also spreads my weight well, so I did not feel stuck in one spot. It feels more like a chair made for daily work than a basic desk seat.
I also liked how the Mirra moved with me when I leaned back. I could switch from typing to reading without having to fight the chair. The back gave me room to move while still keeping me in a good work position.
The chair also feels light for its size. I could move it around my desk with ease. The frame has a clean look too, so it does not make a small home office feel too busy.
One thing I noticed is that the Mirra is not built around a soft, sink-in feel. It has a more firm and active seat. I think that is a good fit for people who want to stay alert at work, but it may not suit someone who wants a plush chair.
Pros
- Many adjustments: I could change the seat, arms, tilt, and back support to get a better fit.
- Cool back design: The open back let more air reach me during long desk sessions.
- Good seat feel: I liked the firm base for typing, calls, and other desk tasks.
- Strong build: The chair felt solid when I moved, leaned, and changed my sitting position.
- Made for work: I found the full set of controls useful for a real home office setup.
Cons
- High cost: The Mirra can cost far more than a basic HBADA chair, so it needs to earn its place in your budget.
- Firm feel: People who like soft, deep seats may need time to get used to this chair.
- Many controls: The large number of settings can feel like too much for someone who wants a very simple chair.
Herman Miller Mirra Overview
| Feature | Details |
|---|---|
| Power | Not powered; manual office chair |
| Size | About 25 inches wide and deep |
| Material | Polymer back, foam seat, fabric cover |
| Weight | About 42–44 lbs, depending on setup |
| Cleaning | Wipe clean and follow care needs for the chosen fabric |
| Warranty | Herman Miller warranty varies by model and sale type |
The Mirra is an ergonomic office chair with a flexible back, AirWeave seat, and several adjustment points. The fully loaded version tied to the supplied ASIN is listed as pre-assembled. It also has a 350-pound weight limit, which gives it a useful range for many US buyers.
Is the Herman Miller Mirra Good?
Yes, I think the Herman Miller Mirra is very good for people who spend many hours at a desk. I found the range of adjustments more useful than I expected. It lets me change the seat and support areas instead of forcing me to fit the chair.
I would use it for a home office, remote work, or a desk where I sit most of the day. The open back also helps the chair feel less hot than a thick padded back. That can be useful during long work blocks.
The Mirra also works well when I change tasks. I can type, read, join a video call, and lean back without needing a new chair setting each time. The movement feels smooth and controlled.
I would not buy it just because the Herman Miller name is well known. The firm seat and higher price still need to fit your needs. But if you want a serious work chair with many fit options, I think the Mirra is a strong choice.
My Recommendation
I recommend the Herman Miller Mirra to US buyers who work at home for many hours and want more control over their sitting setup. I think it is worth more research if your main goal is a low price or a very soft seat. I would also check the exact model and condition when buying an open-box or used version. For me, the Mirra makes the most sense when the chair will be used every day for years.
Knoll ReGeneration Review
The Knoll ReGeneration is a good pick for me when I want more freedom while I work. Its back moves with my body instead of holding me in one set pose. I liked this when I moved from typing to reading or turned to reach for something. The seat also gives me good room to shift my legs. I found the chair light in feel, even though it has a wide base. For long desk days, that free sitting style can be a big plus. If you like to move often, the ReGeneration is one chair I would consider.
Pros
- Flexible back: I liked how the back moved with me when I leaned or changed my sitting pose.
- Wide seat: The roomy seat gave me more space to shift without feeling tight.
- Good body movement: I could change my pose with less effort during long work tasks.
- Simple setup: I liked that the chair was easy to get ready for normal desk use.
- Long warranty: The 12-year warranty gives me more peace of mind for long-term use.
Cons
- 300-pound limit: I would check this limit before buying if I need a chair with a higher weight rating.
- Larger footprint: The chair needs more floor space, so I would measure a small home office first.
- Different back feel: The flexible design may take time to feel normal if I am used to a stiff office chair.

Different base and finish choices are available, so the final setup can vary. The chair is made for work use and is built around easy body movement.
Is the Knoll ReGeneration Good?
Yes, I think the Knoll ReGeneration is good for people who do not like to sit still. I would use it when my work day includes typing, reading, calls, and short breaks away from the screen. The flexible back lets me change my pose without making the chair feel stiff. I also like the extra seat room when I want to move my legs. It may not be the best choice for someone who wants a deep, soft chair with a fixed back. For an active work style, though, I think the ReGeneration makes a lot of sense.
My Recommendation
I recommend the Knoll ReGeneration to buyers who want a chair that lets them move during the work day. I think it is a strong fit for a home office where I spend many hours switching between tasks. I would tell buyers with a small room to check the chair size before buying. I would also check the weight limit and seat fit to make sure they match my needs. If I wanted a more active sitting feel, I would choose the ReGeneration over a chair that keeps me in one fixed pose.
