Main trade-off
SIHOO B300 Pro
Automatic tension does not set seat depth or guarantee the resistance each user prefers.
Head-to-head
Choose B300 Pro for frequent handovers and quick arm clearance. B300 combines flip-up arms with automatic resistance, plus lumbar height and depth controls. Choose original Branch if a padded seat and manual tension are the stronger preferences. Branch’s arms are removable, but that is different from flipping them away between tasks. Neither linked package includes a footrest, and Branch’s optional headrest is not included.
Before you choose
If the chair is pushed under a desk after work and handed to another person later, B300 offers two relevant conveniences: the arms flip away and recline resistance responds to the sitter. Branch can remove its arms, but that is a different setup choice, and tension remains manual. Those differences become more useful as handovers become frequent. A single user who leaves the chair set up may gain much less from them.
What this is based on
Arm clearance and resistance mechanism crossed with daily parking and shared use. No promised time saving or guaranteed desk clearance.
Main trade-off
Automatic tension does not set seat depth or guarantee the resistance each user prefers.
Main trade-off
Arm removal is a configuration change, and lumbar adjustment changes height rather than depth.


B300 Pro vs original Branch for a shared small office. Compare arm clearance, padded versus mesh seating and which adjustments must be reset each day.
These adjustable home-office chairs can serve the same desk, but the B300 combines a mesh seat with automatic recline and flip-up arms. The original Branch keeps a padded seat and manual resistance.
Winner by situation
B300 combines automatic resistance and flip-up arms.
Original Branch supplies that combination.
B300 separates projection from height.
Only B300 remains within its stated rating, with fit still to check.

Someone moving from an ordinary padded chair may already know that they prefer a cushion. Original Branch retains that construction while adding seat-depth and arm adjustments. B300’s mesh seat is a real change, even if its handover features look more convenient. Try the contact surface rather than assuming mesh is more comfortable or cooler for everyone. For a user within both load ratings, the preferred seat can be a sensible reason to choose Branch.
Verified seat construction crossed with a known material preference. No temperature, pressure or long-term comfort measurement.
At a shared desk, a person may find the support at the correct height but too prominent. B300 has a separate depth adjustment, allowing a change in projection without deliberately misplacing the contact height. Original Branch can move the pad vertically or remove it. That can still be acceptable, but it is a different solution. Try B300’s depth setting if preserving some contact is important to both users.
Height and depth versus height and removal crossed with differing contact preferences. No diagnosis or pain-relief claim.

SIHOO, Black standard, without footrest
The chair changes hands often and you want automatic recline resistance.

Branch, Original, Pebble / White, no headrest
You prefer a padded seat and want to tune recline resistance manually.
Meaningful differences
| What changes | SIHOO B300 Pro | Branch Ergonomic Chair | Why it matters |
|---|---|---|---|
| Seat contact | Mesh | Foam cushion | The material preference can matter more than the number of controls. |
| Recline setup | Weight-responsive | Manual tension | B300 removes a handover step, while Branch keeps direct personal control. |
| Arm clearance | Flip-up arms | Removable arms with height, width and depth adjustment | Daily clearance and deliberate removal are different workflows. |
| Lumbar adjustment | Height and depth | Height and removal | Projection and contact height should be treated separately. |
| Rated capacity | 330 lb | 275 lb | A load limit is separate from seat dimensions and comfort. |
What you give up
Recommendation switch
Choose SIHOO B300 Pro. B300 addresses both with its documented mechanisms.
Choose Branch Ergonomic Chair. Branch preserves those preferences while retaining core fit controls.
What matters in practice
The chair needs to be easy to share and park, while the main user may prefer a familiar cushion and a particular recline tension.
