What I Like

• Good Back Support:
  The adjustable lumbar support keeps my lower back from slumping. It helps me stay straight even after long hours at my desk.
• Nice Headrest and Foldable Arms:
  The headrest keeps my neck from bending forward when I’m reading or on a call. The folding armrests make it easy to slide under the desk — great if you have a small space.
• Cool Mesh Design:
  The breathable mesh keeps my back cool. No more sweating during long meetings or editing sessions.
• Strong Build:
  The frame feels solid. The TÜV and BIFMA marks show it passed global safety tests. That gives me peace of mind.
• Fair Price:
  It costs less than a gaming chair but gives real comfort. It’s good value for daily work or study use.

What Could Be Better

• A Bit Firm at First:
  The seat feels stiff for the first few days. It gets softer with time.
• Limited Lumbar Range:
  The lumbar support only moves up and down. I wish it had more depth control.
• Setup Takes a Bit:
  It took me about 25 minutes to build. The guide was clear, but a few parts could come pre-assembled.

Is the Sihoo M102C Good?

Yes, it is. I’ve used it for both work and gaming, and it does the job well. The lumbar support eases my lower back, the mesh backrest keeps me cool, and the headrest saves my neck.

It feels built for people who sit a lot — not just for looks. In short, the Sihoo M102C is a simple, comfy, and reliable chair for home or office use.

What I Like

• Dynamic Lumbar Support Feels Natural:
  The adaptive lumbar system moves with your back as you shift. It gives gentle pressure in the lower spine, helping me sit upright. At first, it felt odd, but after a few hours, it felt just right.
• Smooth Headrest Movement:
  I love how the headrest tilts and slides in all directions. It’s easy to find a spot that fits my neck, whether I’m typing or leaning back.
• Cool, Breathable Mesh:
  The mesh seat and back keep me cool, even after long work sessions. I live in a warm area of the U.S., so airflow matters — and this chair delivers.
• Quiet Weight-Sensing Recline:
  The tilt system adjusts based on body weight. It’s smooth and steady, with no jerky motion when I lean back. It also feels stable — I never worry about tipping over.
• Modern Design:
  The triangular back frame gives it a sleek, modern look. It fits well in both home and office setups without screaming “gaming chair.”

What Could Be Better

• Lumbar Pressure Takes Getting Used To:
  The lumbar support can feel too strong at first. It pushes the back slightly forward, which some users may not like.
• Armrest Stability:
  While the armrests adjust well, they can shift if not locked firmly. It’s minor, but worth noting.
• Seat Depth Fixed:
  The seat doesn’t slide forward or back. A deeper seat option would help taller users find a better fit.

Is the Sihoo Doro C300 Good?

Yes — the Sihoo Doro C300 is one of the best ergonomic chairs under $300. It’s comfortable, flexible, and smartly built for daily use. I’ve used it for both work and gaming, and my back feels supported all day.

The mesh fabric, dynamic lumbar, and weight-sensing tilt make it feel more premium than its price. While the plastic frame isn’t luxury-grade, it’s solid enough for long-term use.

If you’re in the U.S., you’ll also find good customer service and quick delivery options online.
