Main trade-off
SIHOO Doro C300 Pro V2
The large number of moving parts takes time to tune, and the 8D arms may feel overactive.
Head-to-head
SIHOO C300 Pro V2 vs Branch Ergonomic Chair Pro: C300 includes a headrest, Branch offers forward tilt and removable lumbar
The short answer
Choose C300 Pro V2 if you want an all-mesh seat, an included headrest and linked support when you recline. Choose Branch Ergonomic Chair Pro if you prefer a foam seat, forward tilt and lumbar support you can adjust or remove. Both provide seat-depth adjustment, so the choice is more about how you want support to feel.

I need a chair rated for a 300 lb user

What matters in practice
The differences that matter
Branch is about 17.6 lb lighter
That can matter if you frequently move the chair or carry it upstairs.
How we reached this conclusion
59.64 - 42 = 17.64 lb. Branch is 29.6% lighter relative to the SIHOO's published weight. Packaging is excluded.
A headrest requirement changes the package
SIHOO satisfies it as supplied. Branch needs the optional compatible headrest added.
How we reached this conclusion
The compared standard C300 Pro V2 includes a headrest. Branch identifies its headrest as optional.
A 300 lb user exceeds Branch's stated limit
Branch's 275 lb limit rules it out. SIHOO's 330 lb structural rating covers the load, but a 300 lb user is above its automatic weight-sensing range. Confirm recline behavior before choosing it.
How we reached this conclusion
300 is above 275 and below 330. SIHOO separately specifies automatic sensing for 40–100 kg, about 88–220 lb. A structural rating does not establish seat width, recline behavior or body fit.

Meaningful differences
What changes the fit
| What changes | SIHOO Doro C300 Pro V2 | Branch Ergonomic Chair Pro | Why it matters |
|---|---|---|---|
| Seat surface | Suspended mesh | High-density foam cushion | Airflow preference and cushion feel are more meaningful than a broad ergonomic label. |
| Headrest | Included | Optional accessory | Compare equivalent packages if head support is a requirement. |
| Lumbar control | Linked adaptive sacral-lumbar system | Height and depth adjustable, removable | Branch lets you remove the lumbar piece if its contact does not suit you. |
| Forward tilt | Not specified in the compared configuration | Included | Branch gives a documented option for a forward-oriented working position. |
| Published chair weight | 59.64 lb | 42 lb | Branch is about 17.6 lb lighter to move between floors or rooms. |
What you give up
Every choice has a cost
If you choose SIHOO Doro C300 Pro V2
- The official US standard version was backordered when reviewed, while the exact Amazon page showed offer-dependent availability.
If you choose Branch Ergonomic Chair Pro
- The matching headrest is optional, and assembly is easier with a second person.
What matters in practice
How to make the call
Start with mesh versus cushion, then decide whether forward tilt or an included headrest matters more.
A mesh back does not mean a mesh seat
The Branch model in this comparison has a mesh back over a foam seat. C300 Pro V2 uses mesh for both. Buyers who specifically dislike suspended seating should start with Branch. Buyers who want airflow beneath the seat as well as behind the back should start with SIHOO. Neither material guarantees comfort for every person or every length of session.
The headrest changes a like-for-like price comparison
SIHOO includes its headrest. Branch sells one separately, so a buyer who needs head support should compare the complete Branch package with the complete SIHOO package. Someone who never reclines may reasonably prefer fewer parts above the backrest. Treat the headrest as a task preference rather than an automatic upgrade.
The two lumbar systems invite different adjustments
Branch's lumbar cushion moves in height and depth and can be removed. That gives a clear option if you dislike pressure from a separate support piece. SIHOO links parts of its support system to body movement. Its extra mechanical coordination may suit frequent reclining, but the marketing adjustment count cannot tell you whether the support lands in the right place.
What this comparison cannot tell you
- Material, adjustment count and weight limit do not establish a clinical benefit. Comfort and lumbar pressure require an individual fit check.
