Maxi Cosi Romi Convertible Car Seat
Lower PFAS concern; typical car seat materials don't inherently require PFAS, but brand discloses nothing.
The Maxi-Cosi Romi uses standard car seat materials, polyester upholstery, foam, and plastic components, none of which require PFAS by design. Maxi-Cosi makes no public PFAS claim or disclosure. No independent lab data is publicly available for this product.

Why this grade
Category baseline
furniture is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
The Romi uses polyester fabric upholstery, polyurethane foam padding, and an injection-molded polypropylene shell. Polyester and polyurethane are common in car seats because they offer flame resistance, cushioning, and durability in high-use environments. The plastic shell is not expected to leach into food or contact skin directly in ways that trigger classic plastic migration hazards like BPA, since it is not a food-contact surface and car seats are typically used at body temperature, not heating temperatures that accelerate leaching.
The brand's record and disclosure
Maxi-Cosi does not publicly disclose PFAS content, chemical composition, or third-party testing for this seat, consistent with most car seat manufacturers. The brand has no known major recalls linked to chemical hazards. Maxi-Cosi holds certifications for crash safety (NHTSA, ECE) but does not advertise independent chemical safety testing or GREENGUARD Gold or similar certifications. The silence on chemical content is a transparency gap rather than evidence of contamination.
How it compares in its category
The Romi is a mid-market convertible; competitors at similar price points (Graco, Safety 1st, Evenflo) show the same lack of chemical disclosure and similar material palettes. Premium alternatives (Britax, Clek) sometimes reference flame-retardant treatment transparency but rarely commit to PFAS-free certification. Car seats are required by U.S. law to meet flammability standards (FMVSS 213), which often necessitates flame-retardant chemistry; the Romi likely uses brominated or phosphorus-based additives, as is standard, but exact formulations are proprietary.
If you buy it
Inspect the seat before use for obvious damage to foam or fabric; small tears can expose foam directly to skin. Do not leave the seat in extreme heat (above 120°F/49°C) for extended periods, as foam can off-gas volatile compounds under thermal stress. Wash fabric covers per manufacturer instructions (cold or warm water, air dry) rather than dry cleaning, which can damage polyurethane backing. Replace the seat after any major accident or 6-10 years of use, as foam degradation and material fatigue are cumulative.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Flame-retardant chemical exposure (brominated or phosphorus compounds)
Romi must meet FMVSS 213 flammability standards; this typically requires flame-retardant additives in foam or fabric that are not disclosed. Dermal and inhalation exposure during normal use is low but possible with foam degradation over time.
Polyurethane foam off-gassing (volatile organic compounds)
Polyurethane foam can release isocyanates, toluene, and other VOCs, especially when new or if thermal-stressed. Car seats in hot vehicles are exposed to elevated temperatures, accelerating off-gassing; ventilation during breaks can mitigate.
Azo dyes or colorant heavy metals in polyester fabric
No recalls or test reports document azo dyes or lead/cadmium in Romi fabric. Polyester is typically safe for dyes, but proprietary suppliers are not published by Maxi-Cosi.
Formaldehyde resins in fabric sizing or bonding layers
Polyester upholstery and polyurethane lamination can involve formaldehyde-based resins for wrinkle resistance and adhesion. No test data from the manufacturer is publicly available.
Microplastic shedding from synthetic fabrics and shell abrasion
Polyester and polypropylene shed microparticles over time with friction (seat movement, cleaning, wear). Inhalation and ingestion risk is low in a car seat context but non-zero if fabric is heavily deteriorated.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
