What reviewers say about the Doro C300
Two whitelisted testers (Tom's Guide, TechRadar) reviewed the exact Doro C300 after weeks of hands-on use; both recommend it as a comfortable, high-looking all-mesh chair at a mid-range price. Both flag armrests that slide out of place too easily. RTINGS, Wirecutter and PCMag published nothing on this exact model; the Pro/Pro V2/S300 variants (TechRadar has a separate Pro V2 review) were excluded.

I've found the SIHOO Doro-C300 to be comfortable during daily use despite the fact that its lumbar support lacks adjustability
Another hangup I had with the SIHOO Doro-C300 was that its armrests move too easily for my liking.
the non-adjustable lumbar support can be hard to get used to
Assembly time (timed by reviewer): 45 minutes
I have yet to have a day of sitting in this chair that we feel fatigued or like a pressure point is being pressed in any way.
the lower back support is a highly functional lumbar support and provides relief in all the right places
I end up almost falling because the armrests move unexpectedly
