Last Updated on November 7, 2025 by Cassie Moorhead

If you’re stuck choosing between the Hbada P3 vs Sihoo M18, here’s the quick truth — both are great ergonomic chairs, but they suit different kinds of users. After months of using them for long workdays, I found the Hbada P3 fits smaller spaces and offers better posture control, while the Sihoo M18 feels sturdier and wider for taller users. From my experience testing office chairs across the U.S. market, I’ll walk you through how each one performs in real daily use so you can pick the one that truly fits your comfort.

Hbada P3 Review

The Hbada P3 Ergonomic Office Chair surprised me with how well it supports my posture during long hours at my desk. It’s built for people who sit a lot—whether working from home, gaming, or doing creative work. I’ve been using it for weeks now, and the 2D adjustable lumbar support and 145° stepless tilt have made my lower back pain almost disappear. The breathable mesh keeps me cool even during long video calls.

If you want an ergonomic chair that feels premium but doesn’t cost a fortune, the Hbada P3 is a smart pick. It’s a great mix of comfort, function, and solid build quality. In short, it’s a chair that truly makes long sitting hours easier on your body.

What I Like

• Superb lumbar support: The 2D adjustable lumbar system feels like it’s made for my spine. I can tweak it until my lower back feels perfectly aligned, which helps keep my posture straight and relaxed during long typing sessions.
• Comfort that lasts all day: The breathable mesh fabric and soft foam padding make a big difference. Even after hours of work, I never feel sweaty or stiff.
• Smooth tilt and recline: I love the 145° stepless tilt—it lets me lean back for short breaks without losing balance. It feels stable and safe, thanks to the high-strength metal frame and nylon construction.
• Fully adjustable design: Both the headrest and armrests adjust easily. I can fine-tune them for reading, writing, or gaming.
• Certified for quality: Knowing it’s TUV and BIFMA certified gives me peace of mind. It meets safety and durability standards that many U.S. buyers look for when choosing an ergonomic chair.

What Could Be Better

• Assembly could be simpler: The setup took me longer than expected. A clearer manual or labeled parts would help first-time buyers.
• Armrest padding: While the armrests adjust well, the padding could be a bit softer for extra comfort during long typing stretches.
• Color options: I wish there were more finishes available in the U.S. market. A few extra tones beyond black and gray could make it fit better with different home office styles.

Sihoo M18 Review

The Sihoo M18 Ergonomic Office Chair is one of those chairs that feels right from the moment you sit down. It supports your back, adapts to your shape, and keeps you comfortable even during long work hours. I’ve been using it in my home office, and the lumbar support and adjustable headrest make a huge difference when I’m typing or leaning back for a quick break.

It’s sturdy, stylish, and easy to adjust. Whether I’m working at my desk or doing late-night gaming, the Sihoo M18 keeps my posture in check. In short, it’s an ergonomic chair that balances comfort and design without costing a fortune.

What I Like

• Real lumbar support that works: The Sihoo M18’s adjustable back support gives me just the right amount of lower-back comfort. It helps me keep a healthy posture during long sessions in front of my laptop.
• Adjustable everything: The 2D armrests move up, down, and sideways. The headrest tilts to match my neck angle perfectly. It feels like I can customize the chair to fit my body instead of the other way around.
• Cool and breathable: The mesh backrest keeps me cool, even on hot days. It doesn’t trap heat, which is a big plus if you live in a warmer U.S. state or work long hours indoors.
• Comfortable for tall users: I’m 5’10”, and the chair fits my height well. It’s ideal for people around 5’6” to 6’2”, which makes it a solid pick for many users.
• Reliable build quality: The BIFMA certification and 1136 kg static pressure test show this chair is built to last. It’s not flimsy or light—it feels solid and well-balanced when I lean back or move around.

What Could Be Better

• Seat cushioning: The memory foam seat is supportive but could use a little more depth for those who prefer extra padding. After a full day, it feels slightly firm.
• Assembly takes patience: Putting the parts together wasn’t too hard, but the screws took some effort to line up correctly. Clearer labeling would make setup faster.
• Limited color options in the U.S.: I wish the M18 came in more modern colors—something beyond black and gray would blend better in creative workspaces or gaming setups.
