What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Sihoo 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. (2 sourced reviews, 2 lab-tested.)
Praised: All-day comfort over long work sessions; High-end, futuristic all-mesh design that looks good from every angle; Breathable mesh with good airflow.
Flagged: Armrests move/knock out of place too easily horizontally; Lumbar support height is not adjustable (fixed until you recline); Comfort depends on user height; short max height not ideal for taller users.
