Last Updated on October 15, 2025 by Cassie Moorhead

If you’re trying to decide between the Sihoo Doro S100 vs Hbada E3, both chairs offer solid ergonomics but cater to different needs. After using them for weeks, I found the Sihoo Doro S100 excels in firm lumbar support and durability, while the Hbada E3 feels lighter and more flexible for long work sessions. Each has its strengths depending on your sitting style and workspace setup. In short, if you want lasting posture support, go for Sihoo; if comfort and easy movement matter most, the Hbada E3 is worth it.

SIHOO Doro s100 Review

If you sit at a desk all day, this chair can change everything. The SIHOO Doro s100 Ergonomic Office Chair is made for comfort and balance. It feels light but strong, simple but smart. I’ve used it for long editing and writing sessions, and it has made a big difference. The Dynamic Lumbar Support moves with you, and the Intelligent Gravity Mechanism adjusts on its own. You don’t need to pull levers or twist knobs — the chair just fits how you sit. In short, it’s a great mix of support, freedom, and price.

What I Like

• Dynamic Lumbar Support that adapts to you
  The back support follows my every move. When I lean forward to type or recline to rest, it stays right with my spine. It’s smooth and keeps my back happy all day.
• 3D Armrests that move any way you need
  These armrests are super flexible. I can slide them up, down, forward, or back. I even turn them in or out. It helps when I switch between typing, sketching, or gaming.
• 3D Adjustable Headrest for neck comfort
  The headrest adjusts in three ways — up, down, and tilt. I love this feature when I’m on long calls. It supports my neck just right and helps reduce tension.
• Breathable Mesh Seat keeps me cool
  The mesh seat and backrest allow air to flow through. I work from home in the U.S., and it stays cool even on warm days. No sticky feeling like leather seats.
• Trusted safety and quality
  It has BIFMA and TÜV certifications, which means it’s built to last and meets global safety rules. That adds real peace of mind when buying online.

What Could Be Better

• Assembly takes a bit of time
  Putting it together was fine, but some screws were tight. Clearer steps or pre-set bolts would help.
• Seat depth feels short for tall users
  I wish the seat had a bit more range. Taller people might want extra thigh support.
• Armrest padding could be softer
  They adjust well, but feel a bit firm after long hours. A soft top would make them even better.

Is SIHOO Doro s100 Good?

Yes, it’s a great choice. The SIHOO Doro s100 feels like a premium chair at a fair price. The Intelligent Gravity Mechanism reacts to your body weight. When I lean back, it adjusts without effort. No need to twist or guess.

The Dynamic Lumbar Support keeps my lower back in line. I noticed less strain after long sessions at my desk. For U.S. remote workers, this chair fits well with ergonomic office setups that promote health and focus.

I think I’ve finally found an ergonomic chair that truly fits like it’s made for me — the Hbada E3 Air Ergonomic Office Chair. It’s sleek, flexible, and built for long hours at the desk. What surprised me most is how well it adjusts to different body shapes. From the lumbar support to the armrests and headrest, every part can be tuned for comfort.

After weeks of use, I can say it’s one of the few office chairs that feels both supportive and relaxing at the same time. It adapts to my posture, not the other way around. If you’re searching for a big-and-tall ergonomic chair that’s actually worth it, the Hbada E3 might be the one.

What I Like

• Incredible lumbar support – The 3-zone dynamic lumbar system is a game changer. It supports the lower back and adapts to movement, helping me sit straight without strain.
• Super adjustable design – I love how the 3D armrests, seat depth, and headrest all move to match my setup. I can change it from work mode to gaming mode in seconds.
• Gravity-sensing recline – The smart tilt system adjusts automatically to my weight. It reclines smoothly without needing a tension knob.
• Comfort for tall users – I’m over six feet tall, and this chair still fits perfectly. The seat depth and back height make it ideal for tall people who struggle with small chairs.
• Build quality – The frame feels strong yet light, and the mesh keeps me cool during long hours. Plus, it’s BIFMA certified, which means it’s built to last.

What Could Be Better

• Price point – While cheaper than premium brands like Herman Miller, it’s still on the higher side for new buyers. A mid-range version would attract more users.
• Armrest placement – I wish the armrests could move closer to the desk. They sometimes push me a bit too far back.
• Footrest lock – The fold-out footrest is great, but it slides a bit when I move. A locking option would make it perfect for full recline sessions.

Is Hbada E3 Office Chair Good?

Yes — the Hbada E3 is one of the best ergonomic office chairs I’ve tried. It’s not just comfortable; it’s adaptive. Whether I’m working, gaming, or relaxing, it shifts to fit my body. The 3-zone lumbar system gives my back constant support, and the adjustable seat depth helps with leg comfort.

In the U.S., where many people work from home, this chair feels like a smart investment. It suits taller users well and can handle up to 240 kg, which adds to its durability. For me, it’s the perfect mix of comfort, tech, and build quality — without spending a fortune on luxury brands.
