Tech journalist Mack Ashworth recently put the SIHOO Doro C300 Pro ergonomic chair to the test in a GameRevolution review. Over two weeks, he used the chair in both office work and long gaming sessions, evaluating its design, comfort, and adaptability. His verdict gives a clear picture of where this chair excels—and where it could improve.
Futuristic design that works anywhere
The Sihoo Doro C300 Pro has a modern “exoskeleton” look that suits contemporary office spaces and tech-savvy setups. Ashworth highlights that it accommodates a wide range of users, comfortably supporting people from 5 feet to 6’3” in height and up to 300 pounds in weight. While very tall users may find it slightly restrictive, the chair aims for inclusivity without feeling generic.
Comfort features that matter
A standout feature is the ergonomic gaming chair lumbar support, which automatically adjusts to the spine, encouraging better posture during extended periods at a desk or in front of a screen. The backrest is flexible, responding to different sitting positions. While the lumbar system lacks manual depth adjustment, it still provides strong support for most users.
The seat depth is adjustable, paired with a generous cushion, which makes it a comfortable gaming chair for long hours. These elements combine to deliver a seating experience that’s tailored to individual needs.
Flexible armrests—with minor limitations
The 6D armrests allow for a wide range of movement: up, down, forward, back, in, out, and rotation. This makes them versatile for typing, gaming, or reading. However, Ashworth notes that without a locking mechanism, the armrests can move unintentionally—a small frustration but not a deal-breaker. Here, the chair shows its strength as a gaming chair adjustable armrest option.
Simple adjustments, slight learning curve
The chair uses a single-handle adjustment system to control height, tilt, and seat depth. While convenient, it may take some experimentation to find the perfect setup. The headrest adjusts in multiple directions, but Ashworth describes it as “clunky,” with a noticeable click when repositioned—minor quirks in an otherwise well-designed chair.
Verdict: strong performance with minor trade-offs
Overall, Ashworth finds the SIHOO Doro C300 Pro ergonomic chair a solid choice for both work and play. While the headrest and armrest quirks exist, the chair delivers modern styling, adaptability, and ergonomic support.
