If you’ve been looking for a reliable ergonomic chair that won’t empty your wallet, the SIHOO M57 Ergonomic Office Chair might surprise you. After using it for months, I can say it’s one of the most balanced options in its price range. It gives solid lumbar support, smooth recline, and breathable mesh comfort for long hours of sitting.

What I Like

• Premium Design and Materials:
  The metal frame and smooth plastic finish give the M57 a premium feel. When I first assembled it, I noticed how sturdy and refined the parts looked — much better than most chairs in this range.
• Breathable Mesh Comfort:
  I love that the mesh seat and backrest keep me cool even during long work hours. Living in a warm climate, I really appreciate how it prevents sweat build-up — something leather chairs just can’t match.
• Excellent Ergonomics and Adjustability:
  The lumbar support feels supportive yet subtle, and the adjustable headrest helps during long editing or gaming sessions. The recline lock, tilt tension, and armrest adjustments make it easy to find the right posture for my setup.
• Solid Value for Money:
  Compared to high-end chairs like the Herman Miller Aeron, the comfort gap isn’t huge, but the price difference is massive. For most people, this chair gives 80% of the experience for a fraction of the cost.

What Could Be Better

• Armrest Cushioning:
  The armrests are a bit hard. After long sessions, I sometimes rest my elbows on the desk instead. A softer cushion would make this perfect for extended workdays.
• Limited Recline Angle:
  It reclines, but not as far back as I’d like. A few extra degrees would make it more relaxing during breaks or casual reading sessions.
• Headrest Adjustment:
  It takes patience to find the right headrest angle. Once it’s set, it’s fine — but I wish it had a slightly wider range of motion for easier customization.

Is the SIHOO M57 Good?

Yes — the SIHOO M57 is a great ergonomic chair for anyone who spends long hours working or gaming. I’ve used it for both, and it holds up very well. The mesh keeps you cool, the lumbar support helps your posture, and the frame feels built to last.

In everyday use, the SIHOO M57 Ergonomic Office Chair offers a balance between comfort and structure. You can easily switch from typing to leaning back and relaxing without losing support. And since it meets BIFMA and SGS standards, it’s certified for both safety and durability — which is something that matters a lot for U.S. buyers who want verified, long-lasting office furniture.

What I Like

• Solid Build:
  The frame feels strong. The polished aluminum base looks premium and holds weight well. The TUV-3 Chrome Gas Lift (D100) and BIFMA certification make it feel safe and sturdy.
• Breathable Mesh:
  The mesh seat and back keep me cool. It’s perfect for warm rooms or long hours in front of a screen. No sticky feeling, even in summer.
• Smart Ergonomics:
  The adjustable lumbar support helps my lower back. The 3D armrests move in all directions. The headrest adjusts to my height. I also like the adaptive recline mechanism — it leans smoothly with my weight.
• Easy to Set Up:
  The assembly was simple. The tools were all in the box. Everything clicked together neatly in about 20 minutes.

What Could Be Better

• Armrest Padding:
  The armrests are a bit firm. A softer cushion would make typing and editing more comfortable.
• Recline Angle:
  The chair reclines well but could go a bit further back. That would help during quick breaks or relaxed reading.
• User Manual:
  The printed guide could be clearer. The video tutorial helps, but I hope they update the paper manual for beginners.

Is the SIHOO M57 PRO Good?

Yes. The SIHOO M57 PRO is a great ergonomic office chair for daily use. I’ve tested it for both work and play. The support feels natural, and the seat stays cool all day.

The adaptive recline system is impressive — it shifts with your body, not against it. The lumbar support eases tension during long sessions. The mesh material helps airflow, making it ideal for warm offices or home setups.

For U.S. buyers, the BIFMA and TUV certifications mean this chair meets strong safety and durability standards. It’s a smart pick for anyone who values comfort and reliability.

Sihoo M57 vs M57 Pro: Detailed Comparison

I’ve been using both the Sihoo M57 and Sihoo M57 Pro for a few weeks in my home setup. At first glance, they look almost the same — but once I started working long hours, I noticed clear differences in comfort, design, and build quality. Here’s what I found from real use.

My experience:
Both chairs feel sturdy, but the M57 Pro has a smoother polish and a stronger aluminum base. It feels more stable when reclining. The M57 is light and practical, good for small home offices.

Head Support	Fixed angle	3D adjustable neck support
Lumbar Flex	Limited	Moves with your posture

My experience:
After sitting for 6–8 hours daily, the M57 Pro felt much better for my back. Its adaptive recline didn’t make me feel like I was falling backward. The M57 offered decent comfort, but it lacked the “floating support” feel that the Pro gives.

Verdict:
The Pro adapts better to body movement and offers superior ergonomic support.
Ratings:

My experience:
The M57 Pro wins big here. I loved how the Pro’s 3D armrests moved smoothly. The recline tension also adapted better to my body weight, while the M57 needed manual tweaking.

My experience:
As someone who works long hours editing and writing, lumbar support is key for me. The M57 Pro’s adjustable lumbar felt like it moved with my spine. The M57’s support was fine, but static — after hours, I started to feel a bit of tension.

The Sihoo M57 remains a strong pick if you’re just starting your ergonomic setup or want solid comfort on a smaller budget. But for long work hours and daily use, the Pro feels like an investment in your comfort.

If you’re in the U.S. and often work from home, I’d suggest the M57 Pro — it’s designed for long-term sitting, smooth reclining, and it fits modern work-from-home setups perfectly.
