Nuna PIPA urbn vs. Nuna PIPA Lite RX Infant Car Seat Comparison

Nuna PIPA urbn vs. Nuna PIPA Lite RX Infant Car Seat Comparison

In 2021, Nuna introduced the PIPA Lite RX, their top-of-the-line model that combines the best aspects of all seats: "Lite" weight, the RELX base, and a seatbelt-only installation option. The PIPA Lite RX also added exclusive new features like magnetic harness buckle holders and a no-rethread harness for easier height adjustments.

New for 2023, Nuna is introducing the PIPA urbn. The PIPA urbn is the only baseless infant car seat with pipaFIX rigid latch built in, that can install in 2 seconds, all while weighing in at an ultralight 7 pounds.

Both car seats are now available at Strolleria, with the PIPA Lite RX in stock now, and the PIPA urbn available for pre-order, and expected to ship in January 2023. The PIPA urbn will only be available as a travel system with the Nuna TRVL, TRIV Next, or MIXX Next, and will not be sold separately. 

We'll review the features and differences between the PIPA Lite RX and PIPA urbn in this article.

Nuna PIPA Lite RX vs. Nuna PIPA urbn Weight and Specifications

While the carriers themselves are the same size and weight, the PIPA Lite RX does come with the RELX base, making it heavier overall. If you travel often or change vehicles frequently, you might prefer the PIPA urbn for its baseless, 2 second install.

Product Use

  • PIPA Lite RX: 4-35 pounds, or until baby reaches 32 inches tall 
  • PIPA urbn: 4-22 pounds, or until baby reaches 29 inches tall

    • PIPA urbn: does not require a base 

    Nuna PIPA Lite RX and PIPA urbn Safety and Installation Features

    All car seats in the Nuna PIPA series are among the safest infant car seats you could choose for your child.

    Most of the Nuna PIPA series car seats have been rated "best" in crash protection by Consumer Reports, which does independent crash testing to rank car seats on a "good, better, best" scale. 

    The PIPA Lite RX uses a steel-reinforced base that includes a load leg—a steel anchor that extends from the base of the car seat to the floor of your vehicle for additional stability. Consumer Reports found that a load leg reduces the risk of head injury by 46 percent.

    Additionally, the Nuna bases include rigid (steel) LATCH connectors, which Nuna says is 50 percent stronger than the plastic LATCH connectors seen on most infant car seats. The PIPA urbn also uses a similar steel latch connection for its installation.

    Both the PIPA Lite RX and PIPA urbn models use a new type of proprietary, lightweight foam called Aeroflex, a flexible EPP foam that compresses to absorb and diffuse energy away from the baby, with side impact protection for ultimate baby safe keeping.

    How to Install

    Both the PIPA Lite RX and PIPA urbn models can be installed in a matter of seconds, with helpful indicators to signal a safe installation.

    The PIPA Lite RX can be installed using either the RELX base, or using the European-style seatbelt path installation method. 

    The PIPA urbn is installed using the steel-reinforced pipaFIX™ rigid latches that are built into the car seat. There is no base required for the urbn, and it is not compatible with PIPA™ series base or RELX™ base.
