Sihoo Doro C300
Ergonomic office chairs — mid-range full-mesh with self-adapting lumbar · Reviewed by Katie · amazon.com live, Sept 9 2026
Why it scored a 79
At $299.99 the Sihoo Doro C300 is the brand's flagship full-mesh chair and the most-reviewed Herman Miller look-alike on Amazon. Value leads at 85 and Warranty at 88 on a 3-year policy, and Features reaches 74 thanks to a lumbar that tracks your back as you recline, backrest-height adjustment and a headrest, all rare under $400. Quality trails at 64: owners say the headrest sits too low for anyone over six feet, the armrests slide too freely, the mesh seat is firm, and assembly takes two people an hour. It is for an average-height user who wants the most adjustability under $300 and does not mind a firm seat.
