Where these two actually differ
- We flag Azo dyes and formaldehyde resins from textile finishing, Antimony in polyester fiber and Microplastic shedding during washing and use on the Brooklyn Bedding and not on the Helix.
- 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 Brooklyn Bedding.
- The Brooklyn Bedding is polyester/cotton blend mattress encasement with standard zipper where the Helix is polyurethane foam, polyester 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 →
