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 Volatile organic compounds (VOCs) from polyurethane foam and upholstery finish, Undisclosed flame retardants in foam or fabric, Formaldehyde releasers in adhesives or fabric binders and Polyurethane degradation under heat or UV on the Humanscale and not on the Autonomous.
- The Autonomous is mesh fabric (polyester), steel frame where the Humanscale is mesh fabric, aluminum frame, foam cushioning, polyurethane upholstery options, 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 →
