Ever sit at your desk and feel your chair just isn’t pulling its weight? If back pain, lack of support, or endless fidgeting have become part of your daily work routine, it might be time for something better. The Sihoo M57 Ergonomic Office Chair is making waves in the world of home and office furniture, thanks to its thoughtful design, high adjustability, and impressive support. With a mesh back, 3D adjustable armrests, and a customizable headrest, this chair may just be the game-changer your workspace needs.
As a professional reviewer here at RatedByMia, I get to test and evaluate hundreds of ergonomic solutions every year, and the Sihoo M57 caught my eye for good reason. It’s backed by strong Amazon ratings, glowing user feedback, and a lot of buzz from posture-conscious professionals.
In this article, I’ll walk you through everything you need to know in this Sihoo M57 ergonomic office chair review — from its build quality to features, setup process, alternatives, and everything in between.
Who Is It For?
The Sihoo M57 is ideal for:
- Desk-bound professionals working 6–10 hours a day
- Remote workers or gamers seeking lumbar and neck support
- Anyone with mild to moderate back discomfort caused by poorly designed chairs
If you work from home or spend extended hours in front of a computer, having an ergonomic chair is non-negotiable — and this model makes healthy sitting more affordable and accessible. The Sihoo ergonomic office chair M57 provides key features found in premium chairs, such as a mesh design for breathability, lumbar support, and multi-directional adjustability.
That said, those seeking plush cushioning or a laid-back recliner-style experience may not find this chair ideal. It’s a firmer, more upright chair meant to improve posture and reduce fatigue.

Design & Build
Crafted with both function and form in mind, the Sihoo M57 sports a contemporary ergonomic design that looks sleek in a variety of settings — whether that’s a modern home office or a corporate workspace.
The build quality is immediately noticeable the moment you unbox it. The breathable mesh back is tightly woven and offers excellent airflow — a lifesaver during long workdays in warmer climates. The seat cushion is firm yet comfortable, offering just the right balance for all-day use without sinking in.
The base is made of a polished aluminum alloy, giving the chair instant stability and an upscale feel. With smooth-rolling casters and well-fitted moving parts, the chair exudes durability while remaining fluid in motion. It supports up to 330 pounds, which is above average for chairs in its category.
Features & Functionality
Ergonomics are the name of the game, and the Sihoo M57 doesn’t disappoint in that department. Let’s break down some of the most helpful features you’ll enjoy:
- 3D Adjustable Armrests – You can raise, lower, shift forward/back, and pivot the armrests, so your arms stay supported exactly where you want them.
- Built-in Lumbar Support – The lumbar system cradles your lower back and promotes a natural spinal curve. It’s adjustable for height and firmness too.
- Mesh Backrest – Keeps your back cool and fresh, even after long sitting sessions.
- Reclining Mechanism – The chair tilts from 90° to 125°, with a lockable tilt feature that’s smooth and reliable.
- Adjustable Headrest – Tilt and height adjustable, particularly useful for folks around 5’5” to 6’2”.
- Sturdy Class-4 Gas Lift – Ensures stability and safe seat height adjustment underneath a range of desk setups.
These elements work together to actively support healthier posture habits and help reduce back strain over time.
Ease of Use
Setting up the Sihoo M57 is surprisingly straightforward. The box includes all necessary hardware, clear step-by-step instructions, and Allen wrenches required for assembly. If you’ve built an IKEA chair before, you’re already more than qualified to assemble this in under 25–30 minutes solo.
Once put together, adjustments are intuitive. The controls for adjusting height, tilt, and armrests are within reach and react smoothly. There’s virtually no learning curve — just sit down, tweak a few knobs and levers, and you’re good to go.
Performance / Effectiveness
This is where the Sihoo M57 ergonomic office chair truly stands out. It delivers on its promise of comfort and ergonomic performance, especially for extended work sessions. The lumbar support is among the best in its class, especially considering this isn’t a $1,000+ chair. Over multiple workdays, I noticed a significant reduction in shoulder tension and slouching fatigue.
The headrest also does a great job of relieving neck strain — especially handy for those who find themselves leaning forward or looking at screens for long stretches.
Its breathability deserves another shout-out here — thanks to the mesh back, you won’t experience the heat or clamminess that often comes with padded faux leather chairs.
Value for Money
When it comes to ergonomic office furniture, many shoppers struggle to strike a balance between quality and affordability. The Sihoo M57 lands comfortably in the mid-tier segment — offering premium-level adjustability, a solid build, and great ergonomic support.
While you won’t find luxurious extras like memory foam or leather, you will get performance and durability typically reserved for more expensive chairs. You’ll be hard-pressed to find another model with this set of features at such competitive positioning.

Pros & Cons
Pros:
- Highly adjustable (armrests, headrest, lumbar support)
- Durable metal frame with smooth recline
- Breathable mesh design prevents overheating

Alternatives & Comparisons
If you’re considering other ergonomic chairs, one notable competitor is the Hbada Ergonomic Office Chair. It’s also mesh-backed with adjustable features but leans more toward a budget-friendly option. It offers decent support, though its build quality and armrest adjustability aren’t quite on par with the Sihoo M57.
If you’re willing to spend more for premium features, the Steelcase Series 1 is a professional-grade choice that comes with superior build quality and long-term durability — albeit at a much higher price point.
All in all, the Sihoo chair hits a nice sweet spot for those looking for upper-mid-range features without going over budget.
