Researched April 18, 2026

Concerns

  • Isocyanates — occupational asthma risk (leading cause globally)
  • VOC off-gassing: benzene, toluene, formaldehyde detected in new foam products
  • Flame retardant chemicals (often PBDEs or organophosphates) added to foam may migrate out
  • "CertiPUR-US certified" reduces but does not eliminate VOC concerns
