Boost-and-Go: questions answered

From Safety 1st's published specs, last checked 2026-11-06.

Can you bring the Safety 1st Boost-and-Go on a plane?

Yes, Safety 1st lists it as certified for aircraft; look for the red-lettered label that says so. The FAA asks that a car seat go in a window seat so it doesn't block the aisle, and the crew will look for that label.

Boost-and-Go or LUMN: what's different?

By the makers' specs, the LUMN has no added flame retardants (maker's claim). See every spec side by side.

Is it OK to buy a used Boost-and-Go?

NHTSA publishes guidance on used car seats on its car seat page. Safety 1st lists a lifespan of 10 years from manufacture for this model. Check the label and the maker's instructions, and ask your pediatrician about your child.
