The catch
Herman Miller Sayl
A seat slider, arm pivot, added lumbar and forward tilt are all missing from this exact Sayl.
Side by side
Herman Miller Sayl vs Haworth Soji: Soji can change seat length, this Sayl holds to a fixed fit
Quick verdict
Soji is the choice when the chair has to adapt to different seat lengths, forearm positions or lumbar heights. Soji adjusts seat depth, and the selected Mist package includes four-dimensional arms and adjustable lumbar. This Sayl is the choice when its fixed seat and height-only arms already fit and its suspension-back design is the attraction. The linked Sayl has no added lumbar pad or forward tilt. A differently configured Sayl could change the comparison.
Before you buy
Why, and what it costs you
When the desk becomes shared, a chair bought for one person can turn awkward
A fixed Sayl may suit its first user well and still hand over badly to someone with a different seated leg length. Soji’s slider lets that second person move the front edge while keeping their back against the backrest. The seat-height lever on Sayl does not address the same problem. If sharing is likely, choose Soji, unless both people have already tried this fixed-depth Sayl configuration.
Where this comes from
Fixed seat depth compared with adjustable seat depth in a shared-use setting. Body height is not used as a shortcut, and the Soji range is not guaranteed to fit everyone.
The catch
Haworth Soji
The optional forward-tilt package is not established by the selected Soji, and you still need to check the fit.

What this page compares
A shared home office with changing desk tasks is the setting for this Sayl and Soji comparison. Look at the actual Sayl package before assuming its seat, arms or lumbar adjust.
Each is a padded-seat task chair with an open back and a less bulky look than an executive chair. The exact Sayl options matter more in practice than the brand names suggest.

How we worked this out
Fixed seat depth compared with adjustable seat depth in a shared-use setting. Body height is not used as a shortcut, and the Soji range is not guaranteed to fit everyone.
Buying a Sayl does not get you the controls every review shows
You might watch a Sayl review that shows forward tilt, sliding depth and fully adjustable arms, and then open a cheaper-looking Amazon offer. The selected model code specifies none of those three options. The selected Soji package does have the depth and arm controls, but its forward tilt is not established either. Compare package codes before you compare prices, or an apparent bargain may be a different chair configuration that solves a different desk problem.
How we worked this out
Decoding of the manufacturer’s configuration code, set against shopping across channels. No live price gap is assumed and no missing feature is inferred from silence.
Once an arm clears the desk, it may stop supporting the elbow
Under a shallow desk, you can lower Sayl’s arms to clear the underside and still end up with pads too low for the position you wanted. Soji adds front-to-back, width and pivot adjustment, so the pad position can change in more ways than simply going down. That matters if you alternate a compact keyboard and a tablet. Dimensions alone do not prove clearance on either chair, so check the desk apron and your actual working arm height.
How we worked this out
A shallow desk and two device positions are used to compare height-only arms with 4D arms. No undocumented adjustment distance and no comfort benefit.

Spec by spec
Where they really differ
| Spec | Herman Miller Sayl | Haworth Soji | In practice |
|---|---|---|---|
| Seat length | Fixed in the selected F-seat configuration | Adjustable from 16.25 to 18.75 inches | With Soji, the next user can change where the front edge sits. |
| Arms | Height-only H arms | Selected four-dimensional arms | Pad width, depth and angle can change on Soji while the whole chair stays put. |
| Lumbar option | No extra lumbar pad in N2 configuration | Selected adjustable lumbar | Optional support from a different Sayl package does not carry over. |
| Forward tilt | Not included in selected tilt-limiter package | Optional, unconfirmed in the linked Mist package | Buying either linked chair for a forward-tilt setting you merely assume would be a mistake. |

Decision guide
Before you buy
A chair that looks settled in a home office is the aim, though its fit may need to change when another person uses the desk.
What this page can’t tell you
