Spec by spec
Where they really differ
| Spec | Haworth Soji | Branch Ergonomic Chair Pro | In practice |
|---|---|---|---|
| Rated load | 350 lb | 275 lb | Soji's rated load is 75 lb higher. |
| Lumbar adjustment | Height-adjustable pad on the reviewed setup | Height and depth, with removable pad | Branch has a separate control for how far the lumbar projects. |
| Forward tilt | Optional equipment, assumed sold separately | Included | Don't give the Amazon Soji configuration credit for an option nobody has checked. |
| Arms | 4D configuration | 5D | Branch allows finer arm-pad positioning. |
| Delivery setup | Ships assembled | Assembly required | Soji spares you the first build step. |
Trade-offs
What each pick costs you
With Haworth Soji
- When checked, the Mist listing on Amazon had few offers available, but Haworth still sells Soji direct.
With Branch Ergonomic Chair Pro
- The matching headrest is an optional extra, and a second person makes assembly easier.
Change of plan
When the answer changes
You want lower-back firmness and recline on separate controls
Neither model fits. Leap offers a lower-back firmness dial along with manual recline adjustment.
Decision guide
How to decide
An assembled commercial-style task chair with a higher load rating points to Soji. Branch Pro makes sense when adjustable lumbar depth or included forward tilt solves a specific problem.
If you already know how you like to sit
Seat depth, arm placement and manual tilt tension are all covered on Soji, and you do not need a long setup session. Assembled delivery helps in a home office with little floor space. Branch gets more compelling once you can name an extra control you will really use.
Telling lumbar position and firmness apart
Moving a pad up can put it in the right spot and still leave the same pressure. Branch addresses that second issue with depth adjustment and removal. If you buy Soji, test the pad instead of assuming its height adjustment gets the same result.
Look at the exact listing
Soji comes in a family of options. An official photo or configuration menu does not prove that the Amazon Mist listing has every feature. Count the included forward tilt on Branch as a verified advantage until the selected Soji seller explicitly confirms that option.
What this page can’t tell you
- The comparison draws on documented controls and dimensions. We did not measure pressure, durability or comfort in a hands-on test.
- Whether a manufacturer warranty applies turns on seller eligibility and regional terms. Neither chair is presented as a pain treatment.

How many fit
None of the 32 models checked meets all of “I want setup to be simple”, “I need lower-back support I can adjust”, “I lean in for detailed desk work”, and “The seat depth has to fit my legs”, so the pick goes to the closest practical compromise.
