## What reviewers say

**ErgoChair Pro** — Three whitelisted hands-on testers (TechRadar, Tom's Guide, Tom's Hardware) all found the Autonomous ErgoChair Pro a solid, highly adjustable mid-range chair with a comfortable, supportive mesh back and quick, easy assembly. TechRadar was wholly positive, calling it 'phenomenal' for the money. Tom's Guide and Tom's Hardware both flag thin seat padding and a poor fit for taller or larger users, and Tom's Hardware judged it merely average, lacking any standout feature for its ~$449 price. (3 sourced reviews.)

**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.)
