FAQ
1. What makes the Sihoo M57 stand out?
The Sihoo M57 features a full mesh design that promotes superior airflow, ensuring you stay cool and comfortable even in hot weather. It also includes dual-adjustable lumbar support and 3D adjustable armrests for personalised ergonomic support.
2. How does the full mesh design benefit me?
The full mesh backrest and seat provide optimal airflow, preventing sweat and discomfort during long sitting periods. This is ideal for warm environments or extended workdays.
3. Can I adjust the lumbar support?
Yes, the M57 features dual-adjustable lumbar support, allowing you to adjust both vertically and horizontally to fit your spine's natural curve, providing continuous lower back comfort throughout the day.
4. How does the M57 compare to the M18?
- M57: Full mesh construction for maximum airflow and cooling, contoured backrest for “S” shaped spinal support, 3D adjustable armrests, and up to 126° recline.
- M18: Soft sponge cushion for cosy seating, breathable mesh back, height-adjustable armrests, and also reclines up to 126°. The M18 is more suited to users who prefer a cushioned seat, while the M57 is perfect for those who prioritise airflow and cooling.
5. How does the M57 compare to the S100?
The S100 has dual lumbar support, similar to the M57, but offers a greater recline angle of 135° and a more modern design. It's great for users seeking deep recline and extensive shoulder and back support, while the M57 focuses more on cooling and airflow.
6. How do I choose between the M18, M57 and S100?
- Choose the M57 if you need a full mesh design for superior cooling and adjustable lumbar support.
- Choose the M18 if you prefer a cushioned seat with breathable mesh on the back only and adjustable lumbar support for everyday comfort.
- Choose the S100 if you prioritise deep lumbar support, a larger recline angle, and a modern design for both work and relaxation.
7. What is the recline range of the M57?
The M57 reclines up to 126°, allowing you to comfortably relax during breaks.
8. What's the return and exchange policy for the M57?
Every M57 comes with a 3-year warranty, and change-of-mind returns are accepted within 7 days of delivery (see our Refund Policy for the conditions). You can also try the M57 in person at our Sydney or Melbourne showroom before you buy.
M57 is comfortable to sit on, whether that's for a couple hours or more a proper marathon work slog. It's functional and keeps you upright in a comfy way. And I suppose that's sort of perfect given it's a work chair.
Georgia Cogganfrom CREATIVE BLOQ, M57 ergonomic chair review
A quick turn of the wheel behind the chair can lessen or deepen the intensity, and I've found that when working, the soft retention against my spine keeps me comfortably upright.
Aleksha McLoughlinfrom techradar, functional ergonomic chair M57 review
If your budget can't stretch to the higher one, consider M57 fully adjustable ergonomic chair by Sihoo, it comes with a remarkable array of adjustable features and it is great for plenty of adjustments and breathable mesh.

M57 适合谁
M57 适合想要一把像样的人体工学椅——腰托可调、扶手可调、带头枕、全网布坐垫——又不打算升级到高端椅的人。它是澳洲评价数量最多的西昊椅，这是有原因的：坐直伏案所需要的调节它都有；椅背和坐垫都是网布，夏天工作一整天也不闷热；而且用起来不折腾。买它的有学生，有第一次布置家庭办公室的人，也有一次要配六到八个工位的公司。
它不太适合工作时经常后仰的人——椅背绕固定转轴转动，不会跟着你移动——也不太适合身高约 185 cm 以上的人，后者需要坐垫更深的 DORO-C300 Pro V2，或高大身材办公椅系列里的椅子。
想了解腰托、头枕和固定式椅背的实际表现，以及它们适合什么样的人，可阅读我们完整的西昊 Sihoo M57 评测。
适配与尺寸
| 项目 | 数值 |
|---|---|
| 适合身高 | 约 155–185 cm |
| 座高 | 42–52 cm |
| 承重 | 150 kg |
| 后仰 | 可锁定，最大 126° |
| 腰部支撑 | 双向可调：高度和深度 |
| 扶手 | 3D：高度、前后、最多旋转 34°；PU 扶手面 |
| 头枕 | 高度行程 8 cm，旋转 45° |
| 网布 | 椅背和坐垫均为全网布，坐垫前缘为瀑布式 |
| 认证 | BIFMA、SGS |
先调座高，让双脚平放在地面、膝盖与髋部齐平或略低；再把腰托往上调，直到它落在下背部的曲线里，然后调深度，调到有力但不把你往前顶。大多数人在这把椅子上腰托都调得不够，它的调节范围比看上去大。
灰色还是黑色？
同一把椅子，两种配色。黑色是黑色网布配黑色框架——共用办公室的稳妥之选。灰色是浅灰网布配白色框架，在小的家庭办公室里显得更轻盈，和白色或橡木色桌子很搭。两种颜色都带头枕，以及图中所示的抛光铝饰面底座。
M57、M57 Pro 与 DORO-C300 Pro V2 对比
| M57（本款） | M57 Pro | DORO-C300 Pro V2 | |
|---|---|---|---|
| 腰部支撑 | 双向可调腰托 | 自适应——随你移动而伸缩 | 自适应，跟着你动 |
| 椅背 | 固定转轴 | 固定转轴 | SyncroFlex，后仰全程随动 |
| 扶手 | 3D | 4D | 8D 仿生 |
| 后仰 | 最大 126° | 最大 134° | 最大 135°，阻力自动校准 |
简单说：M57 是坐直伏案的实惠之选；Pro 增加了 4D 扶手、自适应腰托和更深的 134° 后仰；C300 Pro V2 再上一级，椅背会跟着你动。我们的 M57、M57 Pro 与 C300 Pro V2 对比逐项讲了其中的差别，最佳人体工学椅指南则把 M57 放到其他品牌中间来看。
