The short answer: buy the SIHOO Doro C300 if you want a headrest, an all-mesh seat that stays cool, and the lowest price. Buy the Branch Ergonomic Chair if you want a padded seat, a cleaner office look and a 7-year warranty instead of 3. Both are mesh-back home office chairs under $400 with adjustable arms and a sliding seat.
Prices in November 2026: SIHOO’s own store has the Doro C300 at $269.99 with code BF20 through November 27, 2026 (regular $559.99), and it’s about $310 on Amazon. The Branch Ergonomic Chair is about $359 on Amazon and $369 to $389 on Branch’s site, with no Black Friday discount on the chair itself.
The standard Branch Ergonomic Chair was recalled on September 3, 2026 because its backrest can detach. Only chairs made from September 10, 2025 to April 22, 2026 are affected, and owners get a free repair kit. Details are below.

Specs are from SIHOO’s US listing and Branch’s spec sheet.
Seat and Comfort
This is the most noticeable difference. The C300’s seat is mesh, stretched over a frame, like its back. It stays cool and doesn’t flatten, but it’s firmer, and some people feel the frame edge on long days.
The Branch has a padded foam seat under a mesh back. It feels softer right away and suits people who find mesh seats hard, but foam runs warmer and compresses over years of use.
Lower-Back and Neck Support
The C300’s lumbar is a sprung pad that moves with your back as you lean and recline, rather than one you set to a fixed height and depth. SIHOO calls it dynamic lumbar support. It works without fiddling, but if it lands at the wrong height for your spine, you can’t move it much.
The Branch’s lumbar is a pad you slide up and down, and you can take it off entirely if you don’t want it.
The C300 includes a headrest, which helps if you recline on calls or lean back to read. Branch sells a headrest separately.
Recline and Arms
The C300 reclines to about 130° with lock points at 110°, 120° and 130°. The Branch uses a synchro-tilt with a 20° range and a tension knob. If you like to lean far back between tasks, the C300 reclines further.
The C300’s 4D arms also move in more directions than the Branch’s 3D arms, which helps line them up with a keyboard tray or a narrow desk.
Weight Capacity, Warranty and Returns
SIHOO rates the C300 to 300 lb and Branch rates its chair to 275 lb. Neither is meant for very heavy users; see our guide to office chair weight limits for chairs rated to 400 lb and up.
The warranties differ more. Branch covers parts for 7 years for the original buyer from Branch or an authorized reseller. SIHOO’s help pages give a 3-year limited warranty on its chairs. Both offer 30-day returns; Branch deducts a $40 fee per returned chair, and it extends returns to January 15 for orders delivered November 5 to December 15.

The Branch Ergonomic Chair Recall
On September 3, 2026, Branch and the CPSC recalled about 16,000 Branch Ergonomic Chairs in the US (recall number 26-735):
- Hazard: one or more of the three backrest anchors may not have been installed correctly, so the backrest can detach. Branch had 11 reports and no injuries.
- Affected chairs: the standard Ergonomic Chair only, made September 10, 2025 to April 22, 2026, with SKUs starting 11-01-00. The manufacture date is on the label under the seat cushion. The Ergonomic Chair Pro is not part of it.
- Remedy: stop using the chair and request a free repair kit (replacement backrest, three bolts and an Allen key) at branchfurniture.com/recall. Branch offers no refunds under the recall.

The C300 is the better value during SIHOO’s Black Friday sale: it costs about $90 less than the Branch and includes a headrest and a deeper recline. The Branch is the better choice if you want a padded seat and a long warranty. If you can stretch to about $494, the Steelcase Series 1 is rated to 400 lb and has a lifetime frame warranty.
