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 Klaussner.
- We flag Flame retardants (chemical identity and type unspecified), Volatile organic compounds (VOCs) and formaldehyde off-gassing, Azo dyes and antimony in synthetic fabrics and Adhesive and backing material off-gassing on the Klaussner and not on the Joybird.
- The Joybird is polyurethane foam where the Klaussner is upholstered furniture, fabric/padding composition unspecified, which is most of the difference in these two grades.
- We are less certain about the Klaussner grade, at 35% 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 →
