We have been using our Nuna PIPA RX car seat since our baby was born 6 months ago. It is so slick, and we love that we can use the seatbelt method if we happen to be using a different car. Baby is comfy in it too.

Great seat! The installis really easy with the belt or LATCH, and the infant insert is so helpful for tiny ones. The base is really heavy, which I was prepared for, but once it's in the car to stay it's not a problem.

Nice seat
November 9, 2023
I had higher expectations for the price of this seat. The canopy has great coverage and it is light weight which is why I chose this specific seat. I also liked this could be easily used without the base with a traditional seat belt if needed. The fabric is color fast and pills easily, luckily this is my last baby but if it wasn’t I would be disappointed in the way it’s worn in just 6 months and would need to replace the fabric for a new baby.
  • Light weight, great canopy coverage, soft fabric
  • Fabric is easily color fast and pills, manual harness re thread to adjust

Purchased the Nuna Pupa RX after several years of using the UPPAbaby Mesa car seat. This seat is definitely lighter and I love that I can still use it on our Vista travel system.

This is the best carrier ever! So light and the base is ultra secure. Easy to clean and take apart to wash. the material is great and washes well. Only negative comment that I have is that the stitching has come apart on one side. It is a little annoying but should be easy to fix. We'll see

This is my second Nuna infant car seat! I used one with my son in 2018, and as soon a I found out I am pregnant, I did not even looked for another car seat as I already knew what I am going to get! Nuna car seats are the best one! Lightweight, my son was always comfortable in it and never cried on our trips! When he grew up we upgraded his carseat to Nuna rava and I can not be happier! He loves it and is always excited to go for a ride !

I love this car seat, very lightweight. My only complaint is that I dislike the two buttons by the handle bar that you have to push in order to remove it from the stroller adapters. I've used this car seat well with the Uppa Baby Cruz and Donkey5.

Great seats!

We needed seats for our twins and went with Nuna because we had the original version of the Pipa back in 2017. They've definitely made improvements and the PIPA RX w/ RELX is a good mid-point between the many Pipa options. We wanted lightweight, the skydrape, the new base, the ability to install without the base, and the ability to buy 2 without spending $1,000. This one hit on the priorities and we've been happy with them!

We wouldn't choose any other car seat
February 22, 2023
Our baby isn't here yet, but after installing it and carrying it around for practice, we couldn't be happier with the safety, design, and softness of the material. The color looks a bit different in person, not as creamy tan, but still really beautiful and well made. The color is growing on me haha.
We have the Mockingbird grow with me stroller and the attachments make it feel really secure, so zero issues there as well. I wanted the best for our babe when it comes to materials used and safety, and we definitely got it thanks to Nuna.

The Pipa RX + Relx Base is great. The base is insanely easy to install and the seat pops in and out of the base with no issues. We use it with the Tavo next and it makes for a perfect travel system. We especially love the sunshade to keep baby cool and unexposed. The seat is lightweight but durable enough to give us peace of mind while driving.

Absolutely love this car seat. Much less bulky than any other car seat and has exceptional safety standards. Plus the look and feel of this makes me happy to be in the nuna family. I just wish the shade on it was easier to use as it does get tight if trying to carry the car seat on your arm instead of with just a hand.

September 20, 2022
Everything is great about the car seat except I don’t think it is worth the price point.
The seat itself is lightweight but the seat belt button at the end hurts my baby’s feet and is poorly thought out! Wish nuna would have thought that one through better. The handle also sits very upfront leaving no real good angle to attach any toys or anything to the car seat itself because it dangles right on his face instead of infront so he can play. The only thing I really enjoy is the relaxed base.
