What distinguishes the C300 Pro V2
The V2 sits between the flagship Doro S300 and the standard C300 Pro in Sihoo's lineup, and it is the only chair in the range built around adaptive support end to end. The lumbar unit is Sihoo's Self-Adaptive Dynamic Lumbar Support 2.0, which tracks your posture as you shift rather than holding one fixed shape. The recline uses Smart Mechanism 2.0 to calibrate resistance to your body weight automatically, so there is no tension dial to tune. Sihoo cites a 40 kg to 100 kg calibration range. The full review breaks down what each of those systems changes and who the upgrade is for.
The 8D bionic armrests are the spec that separates it from the rest of Sihoo's lineup: they adjust in eight directions, including 360 degree rotation and a tilt mode that keeps forearms supported while reclined. The C300 Pro gets 6D arms, while Sihoo's current US C300 page lists 4D coordinated arms. Add the widest headrest in the Doro line, which Sihoo says has a 28 percent larger contact area than the previous model, and the V2 remains the adjustment leader. Its 330 lb rating matches the capacities on Sihoo's current C300 Pro and standard C300 pages rather than topping them.
Historical pricing only
The 2026 sale prices have expired
The Black Standard model was $429.99 during the Independence Day campaign. That figure is retained as a record of the promotion, not as a current offer. Check the official store for today's variant prices and stock.
What the 2026 discount was
The V2 launched in June 2026 at $499.99 and held that price through Sihoo's June sale, where the launch promotion was giveaway entry rather than a markdown. This was the first time the official store listed it lower, so there was no long price history to weigh. The campaign ended July 12, and these figures are retained only as historical context.
We do not show "was" prices for the rest of the lineup on this page because Sihoo's list prices on older chairs sit well above what they have sold for this year. For the V2 the comparison is legitimate: $499.99 is what buyers paid last month.

The Independence Day discount has expired. Use the current-price link on this page to check what Sihoo is charging today before buying.
What was the C300 Pro V2 Independence Day price?

Is the Footrest version worth the extra cost?
It adds a flip-out leg rest that pairs with the 135 degree recline lock. It makes the most sense for reading or rest breaks; upright typists get the same core chair features from the Standard version.
What warranty and return terms come with the C300 Pro V2?
Sihoo publishes a 3-year warranty and a 30-day trial for the C300 Pro V2 bought from its official US store. Confirm the current terms on Sihoo's site before ordering.
