The Nuna PIPA RX combines the safety and style of the best-selling PIPA 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 its predecessor, the Nuna PIPA RX includes the Sky Drape, a unique magnetic cover to protect your baby from the elements, along with a ventilated peek-a-boo window, leatherette handle, and chemical-free fabrics. The PIPA RX can be installed without the base for ease of travel and fits strollers from Nuna and many other brands.

Lightweight but cushioned for baby

I love my Nuna Pipa RX! I went in store before making my decision on a carseat for my new baby and fell in love with this seat. I had compared this to many other carseats on the market and to the lite model and actually preferred this model as living in AZ it was important to have the metal clip holders on the sides. Along with that after removing the infant insert from both you could definitely tell this model has much more cushion for your baby once they grow out of the insert. I am in love with this choice and felt it was the safest on the market for my baby. It was worth every penny for my piece of mind. I definitely recommend the nuna pipa rx!

So glad we went with this

We actually had the Doona for the first 4 months but it was so clear how uncomfortable our little guy was. We went with Nuna due to the organic fabrics and lack of chemicals and saw an immediate difference. He is also in the 90th percentile for height and overall just has more room to relax in this. We’ve been loving how easy it is to take on the go.

Best Features!

When I tell you every family member and friends is in awe with my carseat I mean it! Hands down the most handy carseat. Love the buckle holders ans the magnetic visor that unzips. There has just been so many times where I have been able to utilize the features that are provided. Easily washable as well. We have loved this carseat and plan to continue with the brand through childhood.

Nuna Pipa RX

My husband and I purchased this for our first car seat. We are due any day now. We love how lightweight the car seat is, the stability leg, and the easy instillation! We also love the ability to buy a separate base versus having to purchase a second car seat for each vehicle. We can’t wait to put this to use!

Love it!

Not as hard to install as I thought with the leg. Easy to secure baby and get her in and out of. Wish it wasn't manual rethreading.
