Installation

Installation Method: Rigid LATCH + Seat Belt

This seat installs using Rigid LATCH + Seat Belt. Always check that the seat moves less than 1 inch at the belt path after installation.

1Read the car seat manual and your vehicle owner's manual before installing
2Choose the installation method recommended for your vehicle (LATCH or seat belt)
3Ensure the seat is at the correct recline angle for your child's age
4Test for movement: grab at the belt path and tug — less than 1 inch is correct
5Have your installation checked by a certified CPST for peace of mind

Free inspection available: Visit NHTSA's fitting station locator to find a certified technician near you.

Expert Verdict

If budget is no concern and you want the absolute best crash test performance available, the Nuna PIPA RX is unmatched. Its sensor data in our crash tests surpassed every other seat we've tested. The rigid LATCH makes installation practically foolproof.
