Last Updated on October 15, 2025 by Cassie Moorhead

If you’re comparing the Sihoo M102C vs M57, I’ve tried both and learned what sets them apart. The M102C feels softer and easier to fit in small spaces, while the M57 gives stronger support for long sitting hours. Both are great, but they suit different needs. Let’s look at which one fits your work style and comfort best.

Sihoo M102C Review

The Sihoo M102C ergonomic office chair is simple, strong, and comfortable. I built it myself and started using it right away. It feels solid and supportive, even after long hours of sitting. The seat has a firm base, and the mesh keeps you cool. The folding armrests and easy lumbar support make it great for work or study. If you want an ergonomic chair that works well every day, this one is a smart buy.

What I Like

• Clear setup – The parts were well labeled and easy to follow. It took me some time, but the steps were simple. I liked how every screw had its place, and the tool felt strong.
• Good fit for tall users – I’m over 6’4”, and the chair fits me well. The lumbar support moves up and down to match my back, and the headrest sits right where I need it.
• 3D folding armrests – These move in many ways. They slide forward and back, turn inward, and lift up. It helps when switching between typing and relaxing. They also save space when folded.
• Cool mesh and firm cushion – The seat feels firm but not hard. The mesh lets air move through, so it never feels hot during long use.
• Trusted quality – The M102C has TÜV and BIFMA safety marks. These show it passed strong tests for build quality and comfort. It feels safe and made to last.

What Could Be Better

• Takes time to build – The setup was easy, but there were many parts. A few pre-built sections could make it faster.
• Limited recline – The back leans enough for comfort but doesn’t go very far. More tilt range would help during breaks.
• Armrest padding – The armrests work well but feel a bit firm. Softer padding could make them nicer for long typing sessions.

Is Sihoo M102C Good?

Yes, the Sihoo M102C is a great ergonomic chair for work or home. It supports your back, neck, and arms in all the right ways. I’ve used it for long work sessions and gaming, and it stays comfy all day. The mesh keeps me cool, and the lumbar knob lets me set the right height fast. For people in the U.S. working from home, it’s a space-saving, budget-friendly pick that still feels premium.

What I Like

• Strong build and sleek design – The chair feels solid right out of the box. The metal frame adds strength, and the clean lines make it look premium. I like how it fits into a modern office setup, especially in brighter home offices in the U.S.
• Cool and breathable mesh – The mesh back and seat keep air flowing. Even after hours of sitting, it doesn’t trap heat. This is perfect for warm climates or rooms without much ventilation.
• Custom fit and comfort – I appreciate how easy it is to adjust. The lumbar support moves to fit my lower back. The headrest and 3D armrests adjust in every direction, which helps during typing, reading, or calls.
• Stable base and smooth motion – The aluminum base feels strong, and the wheels glide well across wood and carpet. It gives me confidence that it will last for years.
• Good value – Compared to pricier ergonomic chairs, the M57 offers most of the same features at a fraction of the cost.

What Could Be Better

• Armrest padding – The armrests adjust well but feel hard after a few hours. Softer padding would make them more comfortable for long typing sessions.
• Lumbar rigidity – The lumbar support is firm and might not fit everyone’s back curve perfectly. More flexibility or padding would help.
• Assembly time – It took a while to put together. The instructions are fine, but a few steps could be clearer.

Is the Sihoo M57 Good?

Yes, the Sihoo M57 is a very good ergonomic chair. It’s made for long work hours and daily comfort. The mesh feels supportive but never hot. I’ve used it during long meetings and gaming sessions, and it stays stable and breathable. The lumbar and armrest adjustments help reduce back and shoulder strain. For most U.S. users, especially remote workers, it’s a smart pick that balances comfort, design, and price.
