SIHOO Doro C300 Ergonomic Office Chair

Pros

• +Self-adjusting dynamic lumbar tracks your spine as you move, eliminating the 'lumbar gap' of fixed-lumbar chairs — a feature usually reserved for $600+ chairs, here at $290
• +Three locking recline angles (105 / 120 / 135 deg) give true mid-day-break recline range
• +Full breathable mesh on both backrest and seat — keeps you dry on long workdays better than foam-seat rivals
• +Wide seat (20.28 in) and 300 lb capacity make it fit a broad range of body types
• +Ultra-soft 3D armrests and a solid frame that TechRadar and SitBetterLab call the best ergonomic chair for the price

Cons

• −Seat depth (16.8-17.8 in) runs slightly shallow for very tall users
• −Mesh seat is less plush than a padded seat for users who prefer cushioning
• −Warranty and post-sale support trail legacy office brands like HON and Steelcase
• −All-mesh build feels cold in unheated winter workspaces
