Where these two actually differ
- We flag Volatile Organic Compound (VOC) Off-Gassing, Flame Retardant Chemical Content, Formaldehyde in Adhesives and Binders and Foam Degradation Over Time on the Joybird and not on the Joybird.
- We flag Flame retardant additives (type unspecified), Volatile organic compounds (VOC) off-gassing, Azo dyes in synthetic fabrics and Formaldehyde in adhesives and binders on the Joybird and not on the Joybird.
- The Joybird is polyurethane foam where the Joybird is upholstered fabric, likely polyester blend, 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.
- We are less certain about the Joybird grade, at 45% confidence against 72%, because it discloses less.
Both products run through the same public rubric: 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 →
