Sihoo has quietly become one of the more interesting names in the ergonomic chair space, and the company just made its next move. The Sihoo Doro C300 Pro V2 launched this week at a list price of $499.99, though an Early Bird promotion running from April 16 to May 15 cuts that to $429.99. Stack the coupon code SIHOOIGN on top of that and the price drops further to $404.20 with free shipping.
For a chair with this feature set, that pricing puts it well below comparable ergonomic options that regularly run north of $500.

The split backrest that actually makes sense
Here's the thing that separates the C300 Pro V2 from most chairs in its price range: the backrest is two completely independent components, not one semi-flexible piece.
The lower section handles lumbar and sacrum support, while the upper section covers your back and shoulders. Because they move independently, both sections can respond to your posture separately rather than forcing a compromise between the two. An auto-adjusting headrest sits above it all, filling in the neck and head support that most task chairs skip entirely.
This matters more than it sounds. Anyone who has spent a long session at a desk knows that a single rigid backrest forces you to choose between lower back support and upper back support. The V2 removes that trade-off.
Dynamic support for people who actually move around
The broader design philosophy behind the C300 Pro V2 is what Sihoo calls dynamic adjustability, meaning the chair's components work together to redistribute your weight evenly as you shift positions. The key here is that it handles this automatically rather than requiring you to stop and manually adjust every time you lean forward or recline.
For long gaming or work sessions where you're constantly shifting, rocking back to think, or leaning in during a tense moment, that kind of passive adaptation is genuinely useful.
Manual controls for when you want them
The automatic support doesn't lock you out of manual adjustments. The backrest height moves up and down to fit different torso sizes, and the seat depth slides forward or backward. The 8D armrests cover a wide range of angles and can fold sideways entirely if you need them out of the way.
Recline options include three locked positions at 105, 120, and 135 degrees, plus a rocking mode if you prefer something more fluid. A footrest is available as an add-on for $40, though it doesn't come standard.
Pricing window and what you get with it
The Early Bird promotion runs through May 15, after which the chair returns to its $499.99 list price. Sihoo backs the V2 with a 30-day return and replacement policy and a 3-year warranty, which is solid coverage for a chair in this range.
Also available on Amazon at $450.49 for those who prefer that route, though the direct Sihoo purchase with the SIHOOIGN code gets you the lowest current price.
For gamers spending serious hours at a desk, a well-specced chair at this price point is worth paying attention to. You'll want to check out our latest reviews for more coverage on gaming peripherals and gear, and browse more guides for setup tips across all kinds of gaming hardware.
