Main trade-off
Haworth Soji
The seat is firm and the lumbar pad can feel direct, especially before its height is set correctly.
Head-to-head
Haworth Soji vs Steelcase Series 1: Series 1 adapts recline to shared users, Soji uses manual tension
The short answer
Soji suits someone who wants to set recline tension manually. Series 1 is easier to rotate between users because its resistance responds to body weight.
Before you choose
The reasoning and the trade-offs
The better shared chair needs less resetting
Series 1 removes the need to choose a fresh tension setting for each sitter.
What this is based on

What matters in practice
The differences that matter
The better shared chair needs less resetting
Series 1 removes the need to choose a fresh tension setting for each sitter.
How we reached this conclusion
Compare weight-responsive Series 1 resistance with Soji manual tilt tension.
Seat slides are a shared requirement
Soji provides 2.5 inches of documented depth travel.
How we reached this conclusion
18.75 minus 16.25 equals 2.5 inches. Series 1 also adjusts depth, so its endpoint dimensions must be checked before a fit decision.
Capacity is separate from compact styling
Series 1 carries a 50 lb higher rating despite its compact design.
How we reached this conclusion
400 minus 350 equals 50 lb. Neither figure supplies seat width or comfortable working clearance.

Meaningful differences
What changes the fit
| What changes | Haworth Soji | Steelcase Series 1 | Why it matters |
|---|---|---|---|
| Recline resistance | Manual tension | Weight responsive | Soji offers direct resistance choice while Series 1 adapts to the user. |
| Rated load | 350 lb | 400 lb | Series 1 adds 50 lb of rated capacity. |
| Seat-depth control | 16.25 to 18.75 inches | Adjustable seat depth | Both have a seat slide, so depth adjustment alone does not distinguish them. |
| Back construction | Mesh back | Flexible LiveBack with upholstered or mesh-style cover by configuration | The back structure and finish differ even when both look ventilated. |
| Recline control style | Tension adjustment and upright lock | Weight-responsive mechanism with comfort settings | The practical difference is how often the user needs to retune the chair. |
What you give up
Every choice has a cost
If you choose Haworth Soji
- The exact Mist Amazon page had limited offer availability when checked, though Haworth still sells Soji directly.
If you choose Steelcase Series 1
- Its weight-responsive recline offers less direct adjustment than Leap’s separate recline tension and stops.
Recommendation switch
The decision flips if...
You want higher load capacity with detailed manual back controls
Choose neither. Leap combines a 400 lb rating with manual recline and separate lower-back firmness.
What matters in practice
How to make the call
For a household hot desk
If one person likes firm recline and another is much lighter, resistance settings can become an everyday nuisance. Series 1 handles that transition automatically. Soji works well when users prefer a deliberate personal setting and remember to adjust it.
For a shorter or longer thigh
Both chairs let the seat move. The useful check is whether the correct position leaves clearance behind your knees while your back reaches the support. Soji supplies a documented 16.25 inch minimum. Ask for the exact Series 1 dimensions before assuming equal fit.
For an office buying several chairs
The 400 lb Series 1 rating offers a broader rated load envelope than Soji. That is a screening criterion, not a comfort ranking. A chair can pass the weight requirement and still have unsuitable arm spacing or seat dimensions for a particular employee.
What this comparison cannot tell you
- This comparison uses documented controls and dimensions. We have not measured pressure, durability or comfort in a hands-on test.
- Manufacturer warranties depend on seller eligibility and regional terms. Neither chair is presented as treatment for pain.
