Safety 1st Crosstown All-in-One Convertible Car Seat
Lower-concern for typical use, but Safety 1st makes no PFAS disclosure, contact brand if concerned.
Car seats typically use polyurethane foam, textiles, and plastic without confirmed PFAS in standard formulations. However, Safety 1st has not publicly disclosed PFAS testing or commitments. Flame retardants (often used in car seats for safety regs) may contain PFAS in some cases, though not universally.

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
This convertible car seat combines a plastic shell (likely polypropylene or ABS), polyurethane foam padding, and polyester fabric upholstery. The plastic shell houses the structural frame and attachment points; foam provides impact absorption; fabric covers the user-facing surfaces. None of these materials are inherently problematic at typical use temperatures in a vehicle, though fabric and foam can off-gas volatile compounds during manufacturing and early use.
The brand's record and disclosure
Safety 1st is owned by Dorel Juvenile Group, a major car seat manufacturer with a compliance history tied to federal NHTSA standards rather than consumer-transparency disclosures. The brand publishes no material safety data sheets or chemical certifications for specific car seat lines. No major product recalls specific to chemical contamination have been documented for the Crosstown model, though Safety 1st's silence on PFAS and other intentional additives is typical industry practice rather than exceptional.
How it compares in its category
Convertible car seats in this price range (Safety 1st Crosstown is budget-oriented) typically use similar foam and fabric compositions without formal chemical certifications. Premium brands may disclose fire-retardant chemistry or PFAS-free status, but federal flammability standards (FMVSS 213 for car seats) do not require disclosure of specific chemical additives. The Crosstown's compliance with crash-test standards does not differentiate it chemically from mid-market competitors.
If you buy it
Air out the seat in sunlight for 24-48 hours before use to minimize off-gassing of volatile compounds from fabric and foam. Avoid extended exposure to direct sunlight or temperatures above 140 degrees Fahrenheit, which can accelerate foam degradation and plastic brittleness. Inspect the plastic shell and padding every 6-12 months for cracks, tears, or flattening; replace the seat if foam compression reduces crash-absorption capacity. Wipe fabric with damp cloths rather than chemical cleaners, and dry thoroughly to prevent mold growth in padding.
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.”
Polyurethane foam degradation and particulate shedding
Polyurethane foam in car seats can degrade over 5-10 years of heat and UV exposure, potentially shedding fine particles. Practical risk is low during normal use, but degraded padding reduces crash protection and may generate minor inhalation exposure in confined vehicle cabins.
Volatile organic compound (VOC) off-gassing from fabric and foam
New polyester fabric and polyurethane foam typically emit low-level VOCs (formaldehyde, toluene, benzene precursors) during the first weeks of use. Initial off-gassing is strongest in hot vehicles; airing the seat before first use and ensuring adequate vehicle ventilation minimizes inhaled exposure.
Plastic shell brittleness and cracking under stress
Polypropylene and ABS plastics used in car seat shells become brittle at low temperatures and can crack if exposed to extreme heat or repeated impact stress. Cracks in the shell compromise structural integrity and may expose rough edges; inspect periodically and replace if damage is visible.
Flame retardants in fabric or foam (chemical identity undisclosed)
Federal flammability standards (FMVSS 213) likely require flame-retardant treatment in the fabric or foam, but Safety 1st does not disclose which chemicals are used. Common flame retardants include brominated compounds or phosphate esters; exposure during normal use is minimal unless fabric is ingested or inhaled in particles.
Mold and bacterial growth in foam padding if exposed to moisture
Polyurethane foam absorbs moisture and can harbor mold if the seat is exposed to spills, high humidity, or wet environments without adequate drying. Regular inspection and prompt drying of any wet areas prevents colonization; replace the seat if mold odor or visible growth appears.
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.
