If you want a chair for long desk work, the Silla Mirra 2 Butterfly is worth a close look. I found its flexible back and many simple settings most useful for a home office. The seat also lets me change its depth to get a better fit. My review below covers comfort, fit, build, and value so you can see if this chair fits your needs.
Silla Mirra 2 Butterfly Product Review
The Silla Mirra 2 Butterfly is an office chair made by Herman Miller. The Butterfly back uses a mix of fabric and polymer. This gives the back a soft feel while still keeping it firm. I like this idea for people who move often while they work.
One part that stood out to me is the back support. The chair has PostureFit support for the lower part of the spine. It also has a Loop Spine design that lets the back move as you reach and turn. This can be useful if you do not like a stiff chair.
The seat is made with AireWeave 2. It is built to spread body weight across the seat. The seat depth can also be changed with the FlexFront feature. I see this as a key point for people who need more room for their legs.
The arm rests can be adjusted in height, width, depth, and angle on the listed full-adjust arm setup. This gives me more room to set the chair around my desk. It can also help keep the arms in a more natural place while typing.
The tilt system is another big part of the chair. Harmonic 2 Tilt lets the chair move as you lean back. There is also a three-position tilt limit. I like this for work days when I want to switch between sitting up and leaning back.
The chair is made for movement rather than one fixed sitting pose. The Loop Spine allows some side movement, while the back and seat respond as you shift. That makes the Mirra 2 Butterfly a good match for an active desk setup.
The chair is also made in more than one finish. Herman Miller lists colors such as Graphite, Alpine, Olive, Cordovan, and Ultramarine for the Mirra 2 Butterfly line. This gives buyers more choice for a home office or work space.
For size, the Mirra 2 has a total height range of about 41.8 to 43.8 inches in the listed adjustable-arm setup. The seat height range is about 14.8 to 22.2 inches. The chair is about 26.5 inches deep.
The listed weight limit is 159 kg, or about 350 pounds. That is useful to know before buying because chair fit is not just about comfort. The right size and weight rating matter too.
For care, the Butterfly back needs some care when cleaned. Herman Miller says not to use water or liquid on the fabric and warns against using a brush on it. I would keep this in mind if you want a chair that needs very little care.
What I Like
- I like the flexible Butterfly back because it is made to move with the user.
- The adjustable seat depth gives me a better way to set the chair for my leg length.
- The many arm settings are useful for a desk with a keyboard and mouse.
- The tilt limit gives me more control over how far I lean back.
- The 159 kg weight rating gives this chair a wide range of use.
What Could Be Better
- The chair has many settings, so it can take time to find the best setup.
- The Butterfly fabric needs care, and liquid should not be used on it.
- The Mirra 2 is a high-end office chair, so the cost may be too high for some home office buyers. Herman Miller’s current listings show it as a premium chair line.
My Personal Experience with Silla Mirra 2 Butterfly
When I look at the Silla Mirra 2 Butterfly for a full work day, the first thing I notice is how much freedom the back gives the body. I do not have to stay in one stiff pose. The back is made to flex as I move.
For long work sessions, I would start with the seat height and depth. A chair can have a great back, but the seat still needs to fit the person. The FlexFront seat lets me change the seat depth to suit my legs.
At a home office desk, the arm settings can make a big difference. I can set the arms around the height of my desk and keyboard. That gives me more freedom when I move from typing to using a mouse.
When I want to lean back, the Harmonic 2 Tilt is one of the main features I would use. The chair is built to move with the body instead of making the user fight the tilt.
I also like the three-position tilt limit for work. It gives me a simple way to control the range of the chair. I would use a more upright setting for focused work and a more open setting when reading or taking a break.
For side movement, the Loop Spine is useful in a different way. It lets the back flex as I reach to the side. That is handy in a desk setup where I often reach for a notebook, phone, or other item.
The seat material is also worth noting. AireWeave 2 is made to spread weight across the seat and help with airflow. That makes sense for people who spend many hours at a desk.
For lower back support, the chair uses PostureFit. It is made to support the sacral area and help keep the body in a better sitting position. I would still set the chair to my own body rather than rely on one setting for everyone.
I also think the chair works well for a clean home office. The design is slim and does not look as bulky as some large office chairs. The range of finishes gives buyers more ways to match it with a desk.
One thing I would not ignore is the chair’s care needs. The Butterfly back should not be soaked or cleaned with water. I would use the care steps from Herman Miller before trying any cleaner.
Overall, my view is that the Silla Mirra 2 Butterfly is best for people who want a flexible chair with many ways to set it up. It is not a basic chair with one or two controls. Its main value comes from how the seat, back, arms, and tilt work together.
Comparing With Other Brands
I have also looked at other well-known office chairs, including the Herman Miller Aeron and other high-end work chairs. The Mirra 2 Butterfly stands out most for its flexible back and active sitting design.
Mirra 2 Butterfly vs Other Office Chairs
For comfort, the Mirra 2 focuses on movement. Its Butterfly back and Loop Spine let the chair flex as the user shifts. This is a different feel from a chair that keeps the back in a firm, fixed shape.
For adjustability, the Mirra 2 offers a strong set of controls. The full-adjust arms can move in several directions, while the seat depth and tilt settings give more ways to fit the chair to the user.
For back support, the Mirra 2 uses PostureFit and a flexible back system. I like this mix because it gives support without making the whole back feel rigid.
For price, this is where I would slow down before buying. Herman Miller places the Mirra 2 Butterfly in its high-end office chair range. If your budget is tight, there are many lower-cost chairs to check first.
Recommendation
I would recommend the Silla Mirra 2 Butterfly to a person who spends many hours at a desk and wants a chair that can move with them. It makes the most sense for a home office, work desk, or study space where you sit for long periods.
I would do more research if price is your main concern. A cheaper chair may give you enough support if you do not need many adjustment options.
For a USA buyer, I would also check the exact Amazon listing before ordering. Make sure the listed color, arm type, seat setup, warranty, seller, and delivery terms match the version you want. Different Mirra 2 setups can have different options.
My final pick would be the Mirra 2 Butterfly for someone who values movement, fit, and long-term desk use more than getting the lowest price.
