How they differ in real use
The core difference is philosophy: automatic versus manual lumbar support. The Sihoo Doro C300 uses a dynamic lumbar that tracks your movement and firms on its own as you shift and recline, so support stays on your low back without you touching a knob — ideal for people who move a lot or simply don't want to fiddle. The Autonomous ErgoChair Pro takes the opposite approach with a six-inch sliding lumbar you position manually up or down the backrest, plus 4D arms and an adjustable headrest across nine points of adjustment, so you can tune every contact point exactly. That control is the ErgoChair's strength and, for some, its weakness — it takes time to set up right, and reviewers consistently rate its out-of-the-box seat comfort as good rather than great, whereas the Doro C300's molded seat and automatic support feel dialed-in immediately. Price and warranty also separate them: the Doro C300 costs around $300 with a 3-year warranty, while the ErgoChair Pro runs closer to $500. The ErgoChair counters with the adjustable headrest the Doro C300 lacks and a wider tuning range for unusual body proportions. Both use breathable mesh backs and both recline to offload the spine.

Common questions
Automatic or manual lumbar — which is better for my back?
Both can work; it's about preference. The Sihoo Doro C300's dynamic lumbar adjusts itself as you move, which keeps support in place effortlessly and suits people who shift position often. The Autonomous ErgoChair Pro's sliding lumbar lets you fix support at an exact height, which is better if you want to place it precisely and leave it. If you don't want to fuss, go automatic (Doro C300); if you want control, go manual (ErgoChair Pro).
Is the ErgoChair Pro worth about $200 more than the Doro C300?
Only if you value what it adds: a manually positioned sliding lumbar, an adjustable headrest, and a wider range of adjustment for tuning to unusual proportions. If those matter to you, the premium is justified. If not, the Doro C300 delivers automatic low-back support and immediate comfort for around $300 with a longer 3-year warranty, which is why it ranks above the ErgoChair Pro on our list.
Which is more comfortable right out of the box?
The Sihoo Doro C300. Its molded seat and self-adjusting lumbar feel dialed-in with minimal setup, while reviewers rate the ErgoChair Pro's seat comfort as good rather than exceptional and note it takes time to tune. If you want to unbox, sit, and feel supported quickly, the Doro C300 is the safer choice; the ErgoChair rewards the patience to adjust it.
