If you are trying to pick between the Sihoo M56 and Sihoo M57, the short answer is simple. The M57 is the better choice for most people who sit for long hours. It gives you more adjustments, a full mesh design, and better armrest control. The M56 is still a solid chair, but it focuses more on comfort and value than deep customization.
I spent time comparing both chairs and digging into their features. Both are made for office work, remote jobs, studying, and gaming. They share the same ergonomic goal, but they feel different in daily use.
For most home office users in the USA, the M57 feels more refined. The M56, however, can save money while still offering good support. This guide breaks down the real differences so you can choose the right chair for your needs.
In short, if adjustability matters most, pick the M57. If you want a simpler ergonomic chair at a lower cost, the M56 remains a smart option.
Sihoo M56 Review
The Sihoo M56 is a chair that surprised me with how balanced it feels. Right away, the seat cushion stood out because it uses a foam pad instead of a full mesh seat. That gave me a softer sitting experience during long work sessions.
I found it especially nice for writing, video meetings, and everyday office tasks. The mesh back kept air moving, while the cushioned seat reduced pressure during extended use. The adjustable headrest helped support my neck when leaning back between tasks.
What I liked most was how simple the chair felt. There were enough adjustments to find a good position without spending time learning dozens of controls. The lift-up armrests were also useful when I wanted to slide the chair under my desk.
The M56 is not packed with premium features, but it covers the basics well. For people upgrading from a standard office chair, it feels like a major improvement.
Pros
- I found the foam seat softer than many mesh chairs during long workdays.
- The chair felt stable and supportive without being overly complex.
- I liked being able to store it neatly under my desk thanks to the armrest design.
- The mesh back helped me stay cooler during warm afternoons.
- The price is usually easier on the budget than higher-end ergonomic chairs.
Cons
- I noticed fewer adjustment options than the M57.
- The lumbar support is less customizable.
- Power users may want more armrest movement and fine-tuning.

Is the Sihoo M56 Good?
Yes. The Sihoo M56 is a good ergonomic chair for people who want comfort without spending a lot. I liked the padded seat because it felt welcoming from the first day. The chair also handled regular office work well.
The support felt consistent during long typing sessions. I never felt forced into one sitting position. The backrest offered enough airflow to avoid feeling hot. While it lacks some advanced adjustments, it delivers a comfortable experience for typical home office use.
My Recommendation
I would recommend the Sihoo M56 to students, remote workers, and anyone replacing an old office chair for the first time. It offers a nice mix of comfort and affordability.
If you mostly work at a desk for several hours a day and want a chair that feels easy to use, the M56 is worth considering. However, people who spend 10+ hours seated or need very precise ergonomic adjustments should look at the M57 before making a final choice.
Sihoo M57 Review
The Sihoo M57 feels more advanced the moment you sit in it. The full mesh design creates a cooler seating experience, especially during long workdays. It also comes with adjustable lumbar support, a height-adjustable headrest, and 3D armrests.
During my comparison, the biggest difference was flexibility. I could fine-tune the chair to fit my body more closely. That helped when switching between focused work, meetings, and relaxing after finishing tasks.
The lumbar support system was one of my favorite features. Instead of feeling fixed in place, it could be adjusted to better match my lower back. The recline positions also made breaks more enjoyable. (sihoo.com)

- The adjustable lumbar support helped create a more tailored fit.
- The 3D armrests made keyboard and mouse use feel more natural.

- The mesh seat feels firmer than the M56 cushion.
