Design differences
Branch Ergonomic Chair
A mesh-back task chair with adjustable seat depth, lumbar that adjusts in height and depth, multi-directional arms, tilt tension and tilt lock. It has a clean office look without a headrest.
Sihoo Doro C300
A high-back mesh chair with adaptive lumbar, adjustable headrest and multi-directional arms. It offers more upper-body support for reclining.
Comfort and support
The Branch’s lumbar is set manually and stays where you put it, offering predictable support. The seat-depth slider makes it comfortable across a wide range of leg lengths.
The Doro C300’s adaptive lumbar moves with you, supporting the lower back as you lean. The headrest adds neck support during reclined calls or reading. Its lumbar can feel strong at first for some users.

Fit and adjustability
If seat depth is critical for you, as it is for petite and tall users, the Branch is the safer choice. If headrest and upper-back support matter more, the Doro C300 has the advantage. Check each chair’s seat height range against your measurements.
Build and warranty
Both chairs are well built for their price. Compare warranty lengths, weight ratings and parts availability on current listings. The Branch is usually priced higher than the Doro C300.
How to choose
Choose the Branch for predictable, manually set lumbar, seat-depth adjustment and a clean office look. Choose the Doro C300 for a high back, headrest and adaptive lumbar at a lower price.
A simple way to decide is to picture your typical afternoon. If you spend it typing upright with occasional calls, the Branch’s precise fit pays off. If you spend it alternating between work and leaning back for long meetings or reading, the C300’s headrest and moving lumbar will get more use.
Who each chair suits best
Petite users (under about 5’4″)
The Branch’s seat-depth slider lets you shorten the seat so the backrest actually reaches your back. Pair it with a footrest if the lowest seat height still leaves your feet dangling.
Tall users (over about 6’0″)
The C300’s high back and headrest give more upper-body support, but confirm the maximum seat height. The Branch can also work well if its seat depth is extended fully.
People with lower-back fatigue
Try the Branch if you want a fixed, predictable support point you can set and forget. Try the C300 if you shift position often and want support that follows you.
Video-call heavy roles
The Branch’s lower, cleaner silhouette looks more professional on camera. The C300’s headrest is comfortable for long calls but is more visible in frame.
Setup and care for either chair
Assemble on a soft surface, tighten bolts evenly and re-tighten after the first week. Set seat height, then seat depth where available, then lumbar and arms. Clean mesh monthly with a vacuum brush attachment and a cloth dampened with mild soapy water. Avoid kneeling on the seat or leaning heavily on one armrest, both of which strain the mechanism and mesh over time.
Keep receipts and register warranties on delivery, since both brands handle claims faster when the purchase is on file.
