Description
The Haworth Soji offers a familiar task-chair layout with the adjustments that make a difference at the desk: seat height and depth, arm position, lumbar height and recline resistance. Its mesh back pairs with a cushioned seat, making it a useful choice for someone who wants airflow at the back without a suspended mesh sitting surface.
This Carbon configuration includes the adjustable lumbar support and padded 4D arms. An upright back lock provides a set position for focused desk tasks; release it when you want to recline. The supplied version has a plastic swivel base and hard casters and explicitly excludes forward tilt.
Features
- Height-adjustable lumbar: place the separate lower-back support at the level that suits you.
- Padded 4D arms: adjust height, side spacing, forward/back position and pivot.
- Sliding seat: 2.5 inches of depth adjustment helps match the cushion to your legs.
- Mesh back and cushioned seat: combine back ventilation with an upholstered sitting surface.
- Upright back lock: hold the back upright for tasking or release it to recline.
- Tilt tension: change the force needed to lean back without changing seat height.

A quick Soji fit check
| Shorter seated leg length | Compare your seat-depth needs with the 16.25-inch minimum and leave clearance behind the knees. |
|---|---|
| Desk and keyboard height | Raise or lower the chair for relaxed shoulders; add suitable foot support if your feet no longer reach the floor. |
| Arm placement | Position the pads under your forearms without forcing elbows outward. |
| Carpet or hard floor | The supplied hard casters are generally intended for soft flooring. Confirm a suitable mat or caster choice for a hard surface. |
Know what the back lock does
Soji’s back lock is an upright setting, not a promise of multiple locked recline angles. For movement, release it and adjust the tension until leaning back feels controlled. Forward tilt is a different feature and is absent from this specific chair.
Owner questions about Soji commonly concern seat firmness and whether a headrest is necessary. Its cushion and mesh back will feel different from a deeply padded executive chair. Evaluate the seat dimensions and back contact at your desk, and choose based on the support you use during work rather than the number of advertised adjustments.

Common questions
Does this Soji have lumbar support?
Yes. The separate height-adjustable lumbar support is explicitly included in this Carbon configuration.
Can the seat tilt forward?
No. This specific listing excludes forward tilt, even though it is an option elsewhere in the Soji range.
Are the casters suitable for wood floors?
The supplied wheels are hard casters. Check the flooring maker’s requirements and use an appropriate mat or a verified compatible soft-caster option if needed.
Is the 325 lb figure different from current Haworth pages?
Some current Soji pages show a higher rating. This description retains the 325 lb limit supplied for this fixed configuration rather than assuming it has newer specifications.
