The catch
SIHOO Doro C300 Pro V2
With so many moving parts, tuning takes time, and the 8D arms may feel overactive.
Side by side
SIHOO C300 Pro V2 vs Branch Ergonomic Chair Pro: C300 comes with a headrest, Branch offers forward tilt and a removable lumbar
Quick verdict
C300 Pro V2 suits you if you want an all-mesh seat, a headrest that comes with it and linked support as you recline. Branch Ergonomic Chair Pro suits you if you like a foam seat, forward tilt and lumbar support that you can adjust or take off. Seat depth adjusts on both, which makes this more about how you want support to feel.

I need a chair rated for 300 lb of user weight
Branch's rating is 275 lb. SIHOO satisfies the structural load limit, yet 300 lb is above its automatic-sensing range of roughly 220 lb. Check recline behavior and dimensions first.

In practice
Differences you will notice
Branch weighs about 17.6 lb less
It can count if you often move the chair or carry it upstairs.
How we worked this out
59.64 - 42 = 17.64 lb. Measured against the SIHOO's published weight, Branch is 29.6% lighter. Packaging isn't counted.
If a headrest is required, the package changes
SIHOO meets it as it ships. With Branch, the optional compatible headrest has to be added.
How we worked this out
The standard C300 Pro V2 in this comparison comes with a headrest. Branch identifies its headrest as optional.
Branch's stated limit is below a 300 lb user
Branch is out because of its 275 lb limit. SIHOO's 330 lb structural rating covers the load, but a 300 lb user is above its automatic weight-sensing range. Confirm how it reclines before you choose it.
How we worked this out
300 is over 275 and under 330. SIHOO specifies automatic sensing separately, for 40–100 kg, about 88–220 lb. A structural rating says nothing about seat width, recline behavior or body fit.

Spec by spec
Where they really differ
| Spec | SIHOO Doro C300 Pro V2 | Branch Ergonomic Chair Pro | In practice |
|---|---|---|---|
| Seat surface | Suspended mesh | High-density foam cushion | What counts more than a broad ergonomic label is your preference for airflow and cushion feel. |
| Headrest | Included | Optional accessory | If you require head support, compare packages that are equivalent. |
| Lumbar control | Linked adaptive sacral-lumbar system | Height and depth adjustable, removable | If the lumbar piece doesn't suit how it touches you, Branch lets you take it off. |
| Forward tilt | Not specified in the compared configuration | Included | Branch documents an option for working in a forward-leaning position. |
| Published chair weight | 59.64 lb | 42 lb | When you carry it between floors or rooms, Branch weighs about 17.6 lb less. |
Trade-offs
What each pick costs you
With SIHOO Doro C300 Pro V2
- At the time of review, the official US standard version was backordered. On the exact Amazon page, availability depended on the offer.
With Branch Ergonomic Chair Pro
- The matching headrest is an optional extra, and a second person makes assembly easier.
Decision guide
How to decide
Settle mesh against cushion first. After that, weigh forward tilt against an included headrest.
Do not assume a mesh back means a mesh seat
In this comparison, the Branch pairs a mesh back with a foam seat, while C300 Pro V2 uses mesh for both. If you specifically dislike suspended seating, start with Branch. If you want airflow under the seat as well as behind your back, start with SIHOO. Neither material guarantees comfort for every person or every length of session.
The headrest throws off a like-for-like price comparison
The headrest comes with the SIHOO. Branch sells one separately, so if you need head support, compare the complete Branch package with the complete SIHOO package. If you never recline, you may sensibly prefer fewer parts above the backrest. A headrest is a preference that depends on the task. It is not automatically an upgrade.
Adjusting the two lumbar systems works differently
Branch's lumbar cushion adjusts in height and depth, and you can remove it. If pressure from a separate support piece bothers you, that is a clear option. SIHOO links parts of its support system to your body movement. The extra mechanical coordination may suit frequent reclining, but the adjustment count in the marketing cannot tell you whether the support lands in the right place.
What this page can’t tell you
- A clinical benefit cannot be inferred from material, adjustment count or weight limit. Comfort and lumbar pressure need an individual fit check.
