Last Updated on October 30, 2025 by Cassie Moorhead

Choosing between the Hbada E3 Pro vs Sihoo Doro S300+ can be tricky — both promise great comfort and sleek design. After using both chairs for weeks, I found that Hbada focuses more on breathability and posture, while Sihoo delivers plush comfort and deeper recline support. From long workdays to quick breaks, each chair shines in different ways. If you’re shopping in the U.S., the Doro S300+ stands out for its premium feel, while the Hbada E3 Pro gives solid value and ergonomic performance. Let’s explore which one truly fits your workspace.

Hbada E3 Pro Ergonomic Office Chair Review

The Hbada E3 Pro Ergonomic Office Chair is easy to like from the first sit. It feels strong, looks modern, and gives real back support. I’ve used many chairs, but this one stands out for comfort and balance. The 3-zone lumbar support moves with your body, so your back stays relaxed all day. If you want a chair that blends comfort, build quality, and good looks — this is a great choice.

What I Like

• Comfort that moves with you: The 3-Zone Dynamic Lumbar Support fits the shape of your back. It helps keep your spine straight but never feels stiff. I can sit for hours and still feel good when I stand up.
• Lots of adjustments: The 6D armrests and 4D headrest make a big difference. I like that I can raise, move, or tilt them until it feels just right. It works well for typing, meetings, or relaxing.
• Cool and durable: The mesh seat and back let air flow through. I live in a warm part of the U.S., and this helps a lot during long work sessions. The polypropylene frame and alloy steel base feel strong and stable.
• Nice design: The ombre color mix of pink and blue looks fun yet clean. It fits both home and office setups.

What Could Be Better

• Price: At around $549, it’s not cheap. It costs more than basic ergonomic chairs, but less than high-end brands like Herman Miller.
• Assembly: Putting it together takes time. The headrest clip is tricky and needs patience to align.
• Seat firmness: The seat is firm. It’s good for posture, but if you like soft cushions, this might feel a bit hard at first.

Hbada E3 Pro Ergonomic Office Chair Review

The Hbada E3 Pro Ergonomic Office Chair stands out as a well-built, stylish option for long work hours. It’s a great match for anyone who values posture, flexibility, and comfort. I’ve used it for weeks while writing, editing, and working from home—and I can feel the difference in my back support. The 3-Zone Dynamic Lumbar Support adapts as I move, keeping my lower back relaxed. If you’re choosing between the Sihoo Doro S300 and the Hbada E3 Pro, the E3 Pro gives a more flexible fit for mixed-use setups—ideal for both home offices and study spaces.

What I Like

• Strong posture support: The 3-Zone Lumbar System feels natural and active. It moves with my back instead of pushing against it. During long sessions, this helps me stay upright without effort.
• Excellent adjustments: The 6D armrests and 4D headrest make it easy to find the right position. Whether I’m typing or leaning back to think, I can fine-tune everything in seconds.
• Cool and comfortable mesh: The breathable nylon mesh keeps me from overheating during long work hours. For warmer U.S. climates, this is a real plus.
• Smooth recline: The Auto-Gravity Recline System feels light and balanced. It lets me lean back easily and return upright without any jerky motion.
• Premium build: The polypropylene frame and steel base feel strong. I don’t hear creaks or wobbles, even when I move often during the day.

What Could Be Better

• Firm seat cushion: The seat feels a bit hard at first. It helps posture but may take a few days to get used to.
• Assembly: It took me about 30 minutes to set up. The headrest clip needed extra patience.
• Price: At around $549, it’s more than entry-level chairs. But given the features, it still feels fair for its class.

Recommendation

The Hbada E3 Pro is perfect for anyone who spends hours working at a desk, studying, or gaming. It’s especially good for taller users, offering a full range of motion and strong lumbar support. If you work in warmer U.S. regions, the mesh design will help you stay cool and comfortable.

But if you want a more balanced, breathable, and posture-focused chair for daily office use, the Hbada E3 Pro is a smarter buy.

In short, it’s a durable, ergonomic, and adaptable chair that keeps comfort and spine health front and center—all without the steep premium of ultra-high-end brands.
