Nuna PIPA Lite R Infant Car Seat and RELX Base

Compatibility Guide


The Nuna PIPA Lite R combines the safety and 5.3-pound weight of the PIPA Lite infant car seat with the greater adjustability of Nuna's new RELX base.

Pronounced like "relax," the innovative RELX base solves common installation problems and allows you to customize the fit of your car seat for both your baby and your vehicle. 

The base of the Nuna PIPA RX offers four recline positions, allowing your baby to sit in a more upright position that adds comfort as she grows. 

A steel load leg minimizes forward rotation by as much as 90%, while an anti-rebound panel reduces rearward motion. Steel-reinforced rigid LATCH connectors extend to four positions, creating a tighter fit against your vehicle seat while aiding installation in a wider variety of cars.

The RELX base is easier to install in the safest middle seat position, thanks to the three-position load leg that can be shortened to fit a center seat hump, as well as an improved lockoff for seatbelt installation.

Like the PIPA Lite, the PIPA Lite R weighs just 5.3 pounds—making it 2.6 pounds lighter than the original PIPA and lighter than any other car seat in the world. Despite its weight, the PIPA Lite doesn't skimp on safety, made with a first-of-its-kind flexible foam that compresses to absorb forces in a crash. 

The PIPA Lite R does not include the Dream Drape magnetic cover and cannot be installed without the base for taxis or travel. See this Nuna PIPA Series comparison for a look at the differences between Nuna's five infant car seat models.

      Love Nuna products but….

      I was so thrilled to purchase this Nuna Pipa Lite for our first child. As new parents we were still navigating the road of what are ‘must haves’. Unfortunately we learned a valuable (and costly) lesson. This particular model is not FAA compatible without the base. Meaning it will not work if you were planning to also use it for airline travel and/or rental cars, taxis etc. That was a huge bummer when we realized it after already starting to use it, so it was too late to return.

      We are now having to buy a second Nuna Pipa that can be used for vacations. Strangely the cheaper non lite model offers that ability plus the other Pipa lite models …just not this one. I would say Nuna missed the mark on this particular model and it begs the question, why the heck would they remove the few simple features needed for travel capability.

      In my opinion, this model should come with that disclaimer in bold writing. (I believe I finally saw it somewhere in small print) Otherwise other inexperienced parents like ourselves may totally overlook that and find ourselves having to buy a second one.

      Unfortunately that drawback was a HUGE disappointment.

      Great infant seat

      We used this for our first child and are preparing to use it for our second. Safety was highly recommended and it is super lightweight and great for heavier babies! We also bought the uppababy adapters and (before covid) used that feature all the time!

      Perfect Car Seat

      Love the look and feel of this car seat. We chose it because of how light and safe it is and definitely recommend it.

      Lite and Quality

      We were debating between this infant car seat and the Uppababy Mesa. Both good quality but this one is significantly lighter and can still click into the Uppababy vista stroller with the attachment. Recommend this purchase!
