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 Humanscale.
- We flag VOC off-gassing from polyurethane foam and Polyester/nylon mesh degradation on the Humanscale and not on the Autonomous.
- The Autonomous is mesh fabric (polyester), steel frame where the Humanscale is Mesh (polyester/nylon), plastic, steel frame, foam cushioning, 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 →
