Our Picks
Merino Wool Infant Car Seat
Chemical-treated fabrics
No added flame retardants
Merino wool fabric
Why we picked it: Wool is naturally flame-resistant, which lets some brands meet federal flammability standards without added chemical flame retardants.
FR-Free Convertible Car Seat
Standard treated seats
Rear-facing longer
Wool blend
Why we picked it: Higher rear-facing limits let kids ride rear-facing longer, which the AAP recommends for as long as the seat allows, and wool-blend fabrics avoid added flame retardants.
Lightweight Travel Car Seat
Rental car seats
Light enough to carry onboard
FAA approved
Why we picked it: Look for the label stating the seat is certified for motor vehicles and aircraft; bringing your own seat means you know its history, unlike a rental of unknown age.
Organic Car Seat Cover (Canopy)
Synthetic covers
Breathable sun shade
Organic cotton
Why we picked it: A canopy that drapes over the handle shades baby without anything between baby and the harness; check your seat's manual, since manufacturers warn against add-ons that interfere with harness fit.
Car Seat Travel Bag
Gate-check damage
Padded for airports
Padded nylon
Why we picked it: Padding helps protect the seat from damage during handling, and a bag keeps straps and buckles clean and together.
FAQs
How do some car seats skip chemical flame retardants?
