All Nuna infant car seats—the PIPA, PIPA RX, PIPA Lite, PIPA Lite R and PIPA Lite LX—can use the same base.
When purchasing additional infant car seat bases separately for other vehicles, you can choose from either the PIPA or RELX base—no matter which base was included in the box originally with your car seat.
Learn more about the differences between bases in this PIPA vs. RELX base comparison.
Compare the differences between all Nuna infant car seat models—Nuna PIPA, PIPA RX, PIPA Lite, PIPA Lite R, and PIPA Lite LX—in the video below.
These Nuna infant car seats can be used without the base:
If you're traveling or taking a ride-share, you don't need to bring the base with you, as the Nuna PIPA and PIPA RX can also be installed using only the vehicle seatbelt.
Nuna PIPA Lite models cannot be used without the base. If you have these models, you'll need to install the car seat using the base every time:
While the Lite models are at least 2 pounds lighter than the PIPA and PIPA RX, the drawback is that they lack the belt guide components needed to install the seats with only a seatbelt.
If you travel frequently or live in a city where taxis and ride-shares are common, you'll likely rely on the seatbelt-only installation option for the PIPA or PIPA RX.
No convertible car seats use bases like infant car seats do. Because they are much larger and heavier, a convertible car seat like the RAVA or EXEC will stay installed in your car.
