Branch Ergonomic Chair Pro vs Sihoo Doro C300 Pro V2 Office Chair

The Branch Ergonomic Chair Pro is the better pick for most people: 14 adjustment points, 5D armrests, a removable two-way lumbar support and a 7-year warranty, backed by 1,745 ratings at 4.5. The Sihoo Doro C300 Pro V2 is the stronger choice if you want a chair that moves with you: self-adaptive lumbar, a back-glide recline to 135 degrees, 8D armrests and a wide 3D headrest, with a higher 330 lb capacity and a taller height range. Owners of the Branch praise comfort, tool-free adjustment and easy assembly; Doro owners say support follows them as they move but note it takes a few sessions to dial in. Build is solid on both, but the Branch's longer track record and warranty make it the safer buy.

• Choose the Ergonomic Chair Pro if you want proven, highly adjustable support with a long warranty and a large base of owner reviews.
• Choose the Doro C300 Pro V2 if you want adaptive lumbar and a reclining back that tracks your movement, plus a higher weight limit and taller fit.
