Are car seats safe without flame retardants?
Yes. Several major brands now make car seats that meet fire safety without chemical flame retardants.
What's actually in it
U.S. federal motor vehicle safety rules require car seats to pass flammability tests. Most car seats meet that with added chemical flame retardants in the foam and fabric. A few brands use alternative materials (wool, dense foam construction) that pass without chemicals.
What the research says
A 2025 study in Sci Total Environ showed flame retardants transfer from kids' textiles to skin when baby sweats. A car seat holds a baby for hours at a time.
Look for brands like UPPAbaby, Nuna, or Clek that offer specific no-flame-retardant models. Check the specific model; not all within a brand qualify.
