The catch
HON Ignition 2.0
Finish choices are limited on the all-black Amazon configuration, and the plastic lumbar pad can feel firm.
Side by side
Soji is the pick if you want the selected package's 4D arms, assembled delivery and adjustable seat depth. HON Ignition 2.0 fits a simpler setup, provided height-and-width arm adjustment covers your needs and you do not mind assembling it. A mesh back and a padded seat come on both. The Soji linked here has no forward tilt.
Before you buy
That load is covered by Soji's stated 350 lb limit but not by HON's 300 lb limit.
Where this comes from
325 > 300 and 325 <= 350. It filters on load limit alone, and seat and arm dimensions still have to be checked.
The catch
Finish choices are limited on the all-black Amazon configuration, and the plastic lumbar pad can feel firm.
The catch
A firm seat and a lumbar pad that can feel direct take getting used to, especially until its height is right.

HON Ignition 2.0 and Haworth Soji compared on arm movement, lumbar setup, load limits and the features that come with the Amazon models.
Which one fits
4D arms come with the selected Soji. HON's package establishes adjustment of height and width.
That material combination is used in each selected configuration.
Soji passes the specified load, though dimensions and comfort have to be checked separately.
This exact Soji model on Amazon leaves out forward tilt, and says so.
In practice
That load is covered by Soji's stated 350 lb limit but not by HON's 300 lb limit.
325 > 300 and 325 <= 350. It filters on load limit alone, and seat and arm dimensions still have to be checked.
When you need both arm-pad depth adjustment and pivot, the selected Soji has them, whereas the selected HON only establishes height and width movement.
This conclusion is based on the retail configurations as sold. It does not cover every option offered in either product family.
Haworth's configurable product page offers it, but the linked retail model expressly leaves it out.
What the exact Amazon Soji package says outweighs an optional feature from the wider manufacturer range.

Spec by spec
| Spec | HON Ignition 2.0 | Haworth Soji | In practice |
|---|---|---|---|
| Selected arm package | Height and width adjustable | 4D arms | For different desk tasks, Soji adds movement in depth and pivot. |
| Seat and back | Foam seat, mesh back | Foam seat, mesh back | Preferring cushioning doesn't tell these configurations apart. |
| Published load rating | 300 lb | 350 lb on selected Amazon listing | Soji handles a higher load requirement, though that doesn't prove the seating is wider or more comfortable. |
| Delivery setup | Assembly required on selected listing | Listed as fully assembled | If the seller ships that exact package, Soji can save you an assembly step. |
| Forward tilt | Not established for the selected configuration | Explicitly absent on selected Amazon model | Don't buy this Soji expecting an option that appears on a configurable manufacturer page. |
Trade-offs
Decision guide
Look at the exact arm and mechanism packages instead of stopping at the two family names.
With height and width adjustment, the HON arms sit beside your body at the right level. Soji's 4D arms also shift the pads for depth and pivot. That extra motion helps if the pads need to move closer to a keyboard or turn toward a narrower hand position, and it may add little if you rarely use armrests at all.
Options for Soji at Haworth include forward tilt, different arms and lumbar support. The selected Amazon listing states 4D arms and lumbar but explicitly leaves out forward tilt. HON likewise has mechanisms and arms that depend on configuration. Set a fully optioned manufacturer illustration against a different retail package and you can end up crediting an upgrade that is not in the box.
The selected Soji listing specifies 350 lb, while HON specifies 300 lb. If you weigh more than 300 lb, price alone should not lead you to the HON. Clearing Soji's load limit, though, says nothing certain about seat width, arm clearance or comfort. Check those separately, especially if broader hips or longer legs are the fit requirement that brought you here.
By the numbers
