In this Sihoo Doro S100 review, I’ll share how it feels to sit in it for hours, what works well, and what could be better.

If you’re hunting for a chair that makes long workdays easier, this might be the one worth checking out.

Sihoo Doro S100 Review

I’ve spent years testing chairs, but the Sihoo Doro S100 surprised me. It feels solid, smart, and comfortable right out of the box. If you sit all day for work or gaming, this chair could save your back. It’s easy to adjust, looks sharp, and supports your posture better than most chairs I’ve tried.

What I Like

• Real Lumbar Support That Moves With You
  The Dual Dynamic Lumbar Support works. It shifts as you move. When I lean back, it supports my lower back. When I sit up, it adjusts again. My back stays relaxed all day.
• Backrest Adjusts for Any Height
  The independent backrest is a win. I’m tall, and my girlfriend is short. We both fit this chair without trouble. You can raise or lower it fast. It always hits the right spot for your spine.
• 4D Armrests Feel Smooth and Easy
  The 4D armrests move in every direction. Up, down, forward, or sideways — whatever feels best. I can rest my elbows when typing or drop them lower when gaming.
• Seat Shape Reduces Leg Strain
  The waterfall seat cushion supports your legs well. It takes pressure off your thighs and helps blood flow. I can sit longer without my legs going numb.
• Strong Frame, Light Feel
  The aluminum frame feels tough. Yet the mesh back keeps you cool, even in warm rooms. I live in the U.S., and during long summer days, that breathable design really helps.
• Smooth Recline and Quiet Rollers
  The recline is silent and soft. The wheels glide easily. They don’t scratch my floor or make noise.

Every part of this chair feels built to support you — not fight you.

What Could Be Better

• Setup Takes Time
  It took me about 30 minutes to build it. Not hard, but you’ll want to follow the guide closely.
• Seat Is Firm
  It’s great for posture, but not plush. If you like soft chairs, this one may feel stiff at first.
• Few Color Options
  I’d love more shades. It only comes in a few basic colors. A darker tone would fit my office better.

These are small things, but worth knowing before you buy.

My Personal Experience with the Sihoo Doro S100

After two weeks, I can say this chair lives up to the hype. Here’s what stood out:

• I can sit 8 hours without back pain.
• My posture is better than before.
• The lumbar support moves like magic.
• Adjustments are fast and tool-free.
• The recline is smooth and relaxing.
• Great for gaming and office work.
• Mesh back keeps me cool in summer.
• Works for tall and short users.
• The chair feels premium and solid.
• For the price, it beats many high-end models.

It’s one of those chairs that actually makes sitting feel right.

Comparing With Other Brand

I’ve also used the Herman Miller Aeron — a top-tier chair. It’s amazing but pricey. The Sihoo Doro S100 gives me 90% of that comfort for less than half the cost.
