Which is better for long workdays?

Both are built for 8-hour sitting. The Branch wins on fit because 14 adjustment points and 5D armrests let you dial in posture; the Sihoo wins if you lean back often, since it reclines to 130° with a headrest.

The Branch backs its powder-coated aluminum frame with a 7-year warranty; the Sihoo offers 3 years. The Sihoo is BIFMA and TUV certified, so both are built to commercial standards, but the Branch's coverage is the stronger long-term signal.

Is the Branch worth stepping up to over the Sihoo?

Step up if fit and warranty matter most: more adjustment points, forward seat tilt and a longer warranty. Stay with the Sihoo if you weigh over 275 lb or want a recliner with a headrest included.

Which suits taller or heavier users?

The Sihoo handles more weight at 330 lb. The Branch offers an optional tall cylinder for taller users, but its 275 lb limit is the binding constraint for heavier shoppers.

Do I need the Branch's optional headrest?

Only if you recline at your desk. The Sihoo includes an adjustable headrest; on the Branch it is an add-on with two-axis adjustment.

Branch Ergonomic Chair Pro vs Sihoo Doro C300

The Branch Ergonomic Chair Pro is the more configurable chair: 14 adjustment points, 5D armrests, two-way lumbar, forward seat tilt and a 7-year warranty. The Sihoo Doro C300 counters with a higher 330 lb capacity, a 130° recline, a headrest included and BIFMA/TUV certification, but only 4D armrests and a 3-year warranty. Owners of the Branch praise comfort, tool-free adjustment and back relief; Sihoo owners like the dynamic lumbar and recline for long sessions. Buy the Branch for fit and long-term support, the Sihoo for heavier users and reclining.

Choose the Ergonomic Chair Pro if you want the widest range of fit adjustments, a forward-tilt seat and the longest warranty.
Choose the Sihoo Doro C300 if you need a higher weight capacity, a deep recline and a headrest without adding options.
