Car seats are made primarily from plastic and foam, both of which can contain flame retardants, PFAS, and other toxic chemicals. Children spend significant time in car seats, often in hot cars where chemical off-gassing is accelerated. The foam padding in car seats has been found to contain halogenated flame retardants linked to neurodevelopmental harm.
Why We Recommend This Product
Clek's Fllo is the gold standard for non-toxic car seats. Their Merino wool fire barrier eliminates the need for halogenated flame retardants — the most toxic chemicals in conventional car seats. Greenguard Gold certification verifies low chemical emissions.
