Haworth Soji
A fit grade for the current U.S. Haworth Soji standard-height chair with adjustable seat and 4D arms.
This is a provisional measured-fit grade based only on the published dimensions listed here—not a review, comfort score, or buying verdict. A retired listing stays on record and is no longer scored. Published user-weight capacity, when the manufacturer states one, is an eligibility warning and not part of the geometry grade.
