Where these two actually differ
- We flag Volatile Organic Compounds (VOC) off-gassing from polyurethane foam, Polyester cover degradation and microfiber shedding, Polyurethane foam degradation and chemical leaching with age and Water-resistant coating composition (undisclosed) on the Helix and not on the Nectar.
- We flag Volatile organic compounds (VOCs) from polyurethane off-gassing, Flame-retardant composition undisclosed and Foam degradation and particle shedding over time on the Nectar and not on the Helix.
- The Helix is polyurethane foam, polyester cover where the Nectar is polyurethane foam, cotton/poly blend cover, 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: 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 →
