G5 Infant: questions answered
From Orbit Baby's published specs, last checked 2026-11-06.
Does the Orbit Baby G5 Infant 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 Orbit Baby G5 Infant heavy to carry?
With a 7.5 lb newborn inside you'd lift about 20.5 lb, and that grows as your baby does. The carrier is lighter than 6% of the infant seats we track. See the lightest infant seats.
Can you use the Orbit Baby G5 Infant in a taxi or Uber without the base?
Yes. Orbit Baby lists a baseless install with the vehicle belt; see the manual for the belt routing.
Can you bring the Orbit Baby G5 Infant on a plane?
Yes, Orbit Baby 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 13 lb to carry through the airport.
G5 Infant or Doona Car Seat & Stroller: what's different?
By the makers' specs, the G5 Infant has a rotating seat; the G5 Infant has no added flame retardants (maker's claim); the Doona Car Seat & Stroller has an anti-rebound bar. See every spec side by side.
Is it OK to buy a used G5 Infant?
