Where these two actually differ
- We flag Volatile Organic Compound (VOC) off-gassing, Polyester microfiber shedding and Steel frame corrosion and rust contact on the Autonomous and not on the Steelcase.
- We flag Flame retardant residues in polyurethane foam, Volatile organic compound off-gassing from new foam and polymers and Polymer backrest degradation and potential microplastic shedding on the Steelcase and not on the Autonomous.
- The Autonomous is mesh fabric (polyester), steel frame where the Steelcase is steel frame, polymer backrest, foam seat, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
