Hbada E3 vs Sihoo S300: My Candid Review After Weeks of Use

Last Updated on October 30, 2025 by Cassie Moorhead

Choosing between the Hbada E3 and Sihoo S300 can be tricky — both promise ergonomic comfort but deliver it in very different ways. After using each for weeks, I found that the Sihoo S300 feels more advanced for long hours, while the Hbada E3 fits smaller workspaces and tighter budgets. From my experience testing both chairs in a U.S. home office setup, the real difference lies in back support and build quality. In this guide, I’ll break down what truly matters so you can decide which one fits your daily routine best.

Hbada E3 Air Ergonomic Office Chair Review

I’ve tested a lot of ergonomic office chairs, but the Hbada E3 Air Ergonomic Office Chair honestly surprised me. It’s one of the most adjustable and comfortable chairs I’ve sat in, even when compared to much pricier options. From the three-zone lumbar support to the gravity-sensing reclining system, every part feels designed to match your body—not the other way around. If you sit for long hours, this chair might be the closest thing to a custom-fit seat you’ll find under $600.

What I Like

• Incredible lumbar design: The Three-Zone Elastic Lumbar Support is the best I’ve seen in a mid-range ergonomic chair. I could tweak the height, depth, and even the curve to match my lower back. It feels natural and stays supportive, even after hours of sitting.
• Smart ergonomic adjustability: The T-Shape Support System makes posture adjustment easy. The 3D headrest and 3D armrests let me set my perfect height and angle in seconds. I also like how the seat depth can be moved forward—great for taller users like me.
• Smooth reclining system: The gravity-sensing chassis automatically adapts when you lean back. I didn’t have to adjust tension or find the “right” balance—it just followed my movement naturally.
• Comfort for long sessions: The breathable mesh backrest keeps airflow steady and prevents heat build-up, which is great if you’re working from home in warmer areas like many of us in the U.S. during summer.
• Inclusive and durable build: It’s solid, stable, and rated for higher weight support than most office chairs in its class. The materials feel premium but still flexible enough for everyday comfort.

What Could Be Better

• Seat height range: While it fits most people, taller users (I’m 6’8″) could use a slightly longer gas lift for more leg clearance. A taller piston option would make it nearly perfect.
• Armrest proximity: The armrests sit a bit wide, which sometimes pushes me a few inches back from my desk. I’d love more inward slide range for close typing.
• Footrest lock: The fold-out footrest is great for reclining, but it doesn’t lock firmly in place. A small latch or lock system would make it feel more stable.

Sihoo S300 Review

The Sihoo Doro S300 Ergonomic Office Chair feels like comfort meets smart design. From the first sit, it molds to your body and moves as you move. The dual dynamic lumbar support hugs your back with gentle pressure, and the 6D armrests shift in every direction. After a full workday, my back felt supported, not stiff. If you sit for long hours, this chair can make a real difference.

What I Like

• Smooth Recline That Feels Weightless: The aerospace-grade elastic system makes leaning back feel natural. You can stop at any angle without locking it. It’s like floating in air.
• Smart Back Support: The bionic lumbar pads move with your spine. When I type or lean, the support adjusts on its own. It feels alive, not rigid.
• Cool and Soft Fabric: The Italian velvet mesh stays cool even on long days. It’s soft, breathable, and easy to clean.
• Solid Metal Build: The frame is aluminum alloy. I’m 6’4” and 200 lbs, and it holds steady without a sound.
• Quick Adjustments: The controls are simple. Seat height, recline, and armrest angles change fast and stay firm.

What Could Be Better

• Price: It’s a premium chair and may feel costly for some. A mid-range version could attract more buyers.
• Seat Depth: A little more range would help taller users stretch out.
• Color Options: Fewer colors to choose from. More tones would help match U.S. home office styles.

Hbada E3 vs Sihoo S300: Detailed Comparison

I’ve used both the Hbada E3 and the Sihoo Doro S300 for weeks while working from home. Both promise ergonomic comfort, but they deliver it in very different ways. The Hbada E3 is simple, light, and ideal for compact spaces. The Sihoo S300, on the other hand, feels more advanced — like a luxury car seat that adjusts to your every move. Let’s break down how they compare in real use.

Design and Build Quality: Hbada E3 vs Sihoo S300

Feature	Hbada E3	Sihoo S300
Frame Material	Nylon and steel blend	One-piece aluminum alloy
Backrest Design	Mesh with flexible lumbar pad	Four-axis coordinated support system
Seat Material	Breathable mesh	Italian velvet mesh + DuPont TPE
Look & Feel	Light and minimalist	Futuristic, premium, steampunk vibe

I loved the E3 for its simplicity — it fits small spaces and feels airy. The S300 felt more solid and sculpted, like it was built for long-term comfort. If you value build quality and design, the S300 stands out.

My Rating:

Hbada E3 – 8/10

Sihoo S300 – 9.5/10

Seat Depth	Fixed	Adjustable slide system
Lumbar Support	Basic dual pads	Dynamic (bionic) lumbar system
Recline Mechanism	Manual tilt with lock	Aerospace-grade elastic system (weightless recline)

The E3 gave me solid comfort for short work sessions, but the S300 felt like it was reading my posture. I could lean back at any point, and it stayed balanced — no locks needed. The dual dynamic lumbar support kept my spine straight even when shifting around.

My Rating:

While both support the spine, the S300’s system moves with your body — it’s almost “alive.” The E3 gives basic lumbar comfort, but it doesn’t adjust dynamically. The S300 wins for adaptive ergonomics, especially if you sit for 8+ hours a day.
