X: questions answered

From Doona's published specs, last checked 2026-11-06.

Does the Doona X rear-face longer than other infant seats?

24 of the 97 infant seats we track rear-face to a higher weight than its 30 lb. The highest is the Baby Jogger City GO 2 at 35 lb. NHTSA: stay rear-facing "until he or she reaches the top height or weight limit allowed by your car seat's manufacturer." (NHTSA)

Is the Doona X heavy to carry?

With a 7.5 lb newborn inside you'd lift about 27.1 lb, and that grows as your baby does. The carrier is lighter than 2% of the infant seats we track. See the lightest infant seats.

Can you use the Doona X in a taxi or Uber without the base?

Yes. Doona lists a baseless install with the vehicle belt; see the manual for the belt routing.

Can you bring the Doona X on a plane?

Yes, Doona 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. It weighs 19.6 lb to carry through the airport.

Is it OK to buy a used X?

NHTSA publishes guidance on used car seats on its car seat page. Check the label and the maker's instructions, and ask your pediatrician about your child.
