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 Polyurethane foam off-gassing (VOC) and Plastic base component degradation on the Humanscale and not on the Autonomous.
  • The Autonomous is mesh fabric (polyester), steel frame where the Humanscale is Aluminum frame, foam padding, textile upholstery, plastic/polymer base components, 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 →
