Description
Nuna products are known for being well-made. Color-coded indicators (green means installation is complete; red tells you there’s more to do) let you know when the base is connected correctly so you can travel with confidence. It’s also easy to install without the base—handy for parents who often rideshare.
This seat gets points for safety and comfort. It has side-impact protection and a base with a fold-down stability leg that wedges against the car floor. The leg absorbs collision forces in an accident and stabilizes your baby’s ride the rest of the time (it’s a locking 3-piece design that makes it a better fit for different types of cars and the middle seat).
The base also has an anti-rebound panel that helps achieve a tight install and prevents extra motion. There’s more: the steel-reinforced rigid latch has four positions for a better fit against your vehicle seat.
The bubble-free, numbered recline means you can change positions as your baby grows without having to uninstall the base. The low-profile base also allows for easier loading of the car seat.
The vehicle seat belt lockoff makes belt routing easy with the open belt path, and opens smoothly with the touch of a button. Natural belt angles for lap and shoulder belts accommodate more vehicles.
Another parent favorite: the Sky drape pulls down smoothly and attaches quietly with magnets, creating a shelter that harbors baby from the elements, while the mesh window lets you check in. The canopy is UPF 50+ canopy with a flip-out eyeshade for added protection.
The Pipa RX comes with a two-piece removable infant insert made from organic jersey and head support that customizes to baby’s shape. All the materials used are flame resistant, but without any added fire retardant chemicals.
Two more noteworthy details: buckle holders keep the buckle out of the way when you’re putting in baby and the luxe leatherette handle adds a chic touch. An additional Relx Base can also be purchased for multiple vehicles.
If you want to attach your infant car seat to a stroller, the PIPA is compatible with many popular stroller brands. You can connect it directly to the Nuna Demi Grow, MIXX, TAVO, PEPP (adapter included), or another option: the UPPAbabyVista and Cruz (2015 and newer models; do not use RumbleSeat) with an adapter (sold separately).
Pine is a Babylist exclusive, so you’ll only find it here.

Beautiful car seat, incredibly easy install
My husband and I gave in and ordered this very pricey car seat after first trying out the Graco SnugRide SnugFit carseat. We started with the Graco because we figured the bells and whistles didn't matter as long as the car seat was safe. Well...the install with the Graco made our hands raw and slightly damaged the leather seat in our Porsche (that's where my husband drew the line lol). We went with the Nuna because the base install couldn't have been easier, and I hate to admit it (because I…

Literally a Lifesaver
I got in a bad car accident with my little one: T-boned, all airbags deployed, the works. My 4-month-old did not have one bump, scratch, scrape, or bruise on her. She was even smiling for the paramedics. Needless to say I will be repurchasing this car seat again for my replacement and for all my future children too.

Easy to carry, stylish, works well with our vista. Piece of mind in regards to safety. Certainly expensive.

Exceeded expectations! Fantastic product!
Was between this and the UPPA, and I'm so glad we chose Nuna. Our baby feels so comfortable in this seat, and is very safe and secure. From a newborn size to almost six months old, it has transitioned well with him. 10/10! Will forever remain a Nuna mom!

Worth the wait
I just got my car seat in the color pine after waiting for months. I absolutely adore the color, it’s definitely green in person (comes across as very grey in photos), but it does has grey unders tones. For me I wanted a little color, and this is definitely green, but it doesn’t scream obnoxious. It seems super stable, it’s nicely put together and light weight. I will say, it comes in a pretty big box that’s awkward to carry (even with a handle) so make sure you have someone to help you carry it in! No complaints so far!

Must have
I received this as a baby shower gift and I love it. It is super soft, easy to install and carry in and out. Definitely would recommend as a new mama.
