Nuna Next Stage Car Seats | What's Next After the PIPA?

At Bambi Baby, we’ve had the pleasure of serving countless families over decades in the baby gear world. One thing we’ve learned? Parents of little ones all share one mission — finding the best Nuna car seat. Whether your baby is outgrowing their beloved Nuna PIPA infant car seat or you’re building your registry from scratch, Nuna is always (and should be!) part of the conversation.

Nuna embodies luxury, safety, and innovation in every design, with signature touches that set it apart from the rest. Known globally for its future-forward, stylish, and functional baby gear, Nuna has earned parents’ trust by putting safety, comfort, and ease of use at the forefront. At the heart of its lineup sits a thoughtfully engineered car seat collection that evolves alongside your child.

The Nuna PIPA series is one of the most popular infant car seat lines worldwide, offering premium safety and comfort for babies, paired with user-friendly features parents love. And because that first experience is so exceptional, many families stay loyal to Nuna through every stage of their car seat journey.

The Next Step After the Nuna PIPA

Choosing Nuna is the easy part — the challenge comes when it’s time to transition to your next-step car seat. Nuna’s lineup can feel overwhelming at first, with five impressive models to choose from. In this guide, we’ll break down each of Nuna’s next-step car seats, highlight key differences, and help you determine which one fits your family best.

You’ll also learn about Nuna’s one-of-a-kind features, advanced safety integrations, and GREENGUARD Gold Certification, which ensures that every Nuna car seat is crafted from materials that meet strict chemical emissions standards for healthier indoor air.

Nuna's Toddler and Next-Step Car Seats

Nuna currently offers five car seats beyond their infant car seat lineup. Three of these seats can be used both rear- and forward-facing, making them ideal for families looking for long-term solutions. While many parents begin with an infant car seat for portability and stroller compatibility, convertible car seats are just as safe for newborns and can be used for years — well beyond the typical one-year infant car seat phase.

If you’re looking to invest in a seat that grows with your child, the Nuna REVV Maxx, RAVA Next, and EXEC Next are all excellent options for use from birth.

For older toddlers and big kids, Nuna offers two forward-facing only models that provide a tailored fit and comfort as your child grows. Considering that children can need a car seat until as late as age 12 (as recommended by the NHTSA), having a clear plan for your child’s car seat journey can save both time and money in the long run.

Before diving into each model, let’s look at the types of car seats in Nuna’s next-step lineup:

Nuna's Next-Stage Car Seat Line-Up

• Nuna REVV Maxx: Rotating Convertible Car Seat
• Nuna RAVA Next: Convertible Car Seat with Extended Rear Facing Capability
• Nuna EXEC Next: All-in-One Convertible Car Seat
• Nuna LUMN: Forward Facing Transitional Harness to Highback Booster Car Seat
• Nuna AACE: 2-in-1 Highback to Backless Booster Car Seat

Now that you have a side-by-side look at the Nuna next-stage car seat lineup, let’s take a closer look at each model. Below, we’ll break down what makes each Nuna car seat stand out, which stage it supports best, the key features parents love, and why it may be the right choice after the PIPA.

Nuna REVV Maxx - Rotating Convertible Car Seat

Rotating car seats are having a major moment — and for good reason.

FAQs About Nuna Car Seats

What Nuna car seats fit onto Nuna strollers?

Only Nuna infant car seats are stroller-compatible. Nuna PIPA Series infant car seats click into Nuna strollers for travel-system use. Nuna convertible car seats, all-in-one car seats, harness-to-booster seats, and booster seats do not attach to strollers.

Are all car seats stroller-compatible?

No. Only infant car seats are designed to click into a stroller for travel-system use. Convertible car seats, rotating convertible car seats, all-in-one car seats, harness-to-booster seats, and booster seats are designed to stay installed in the vehicle and are not stroller-compatible.

How long can my baby stay in their infant car seat?

Babies typically outgrow their infant car seat around their first birthday, but always check the height and weight limits on your specific model. Most infant car seats are used up to about 30 pounds and around 30 inches. In many cases, babies outgrow the height limit before they reach the full weight limit.

When should I purchase a convertible car seat?

It is smart to add a convertible car seat to your registry so you are prepared before your baby outgrows their infant seat. If you decide to wait, start researching and comparing convertible car seats when your baby is around six months old. This gives you time to choose the right seat, allow for shipping, and get familiar with the installation before you need it.

What is the next-step car seat after the Nuna PIPA?

After the Nuna PIPA, your baby should continue riding rear-facing. The next step is a rear-facing convertible car seat, such as the Nuna RAVA Next, Nuna REVV Maxx, or Nuna EXEC Next.

Which Nuna car seat is best after the PIPA?

For many families, the Nuna RAVA Next is the most popular next step after the PIPA because it offers extended rear-facing use, a straightforward installation process, and a compact rear-facing fit. Families who want easier loading and unloading may prefer the Nuna REVV Maxx, while families looking for one long-term seat may prefer the Nuna EXEC Next.

What is the difference between the Nuna RAVA Next, REVV Maxx, and EXEC Next?

The Nuna RAVA Next is a traditional convertible car seat with extended rear-facing use and a compact rear-facing fit. The Nuna REVV Maxx is a rotating convertible car seat designed for easier loading, unloading, and switching between rear-facing and forward-facing. The Nuna EXEC Next is an all-in-one car seat that transitions from rear-facing to forward-facing to booster mode, making it the longest-use option in the Nuna lineup.

What is the difference between a convertible car seat and an all-in-one car seat?

A convertible car seat typically transitions from rear-facing to forward-facing with a 5-point harness. An all-in-one car seat adds a booster mode, allowing the seat to cover more stages. In the Nuna lineup, the RAVA Next and REVV Maxx are convertible car seats, while the EXEC Next is an all-in-one car seat.

Can I use a convertible car seat from birth?

Yes. Many convertible car seats, including the Nuna RAVA Next, Nuna REVV Maxx, and Nuna EXEC Next, are approved for use from birth and include newborn support to help provide a safe, snug fit. However, many families still choose to start with an infant car seat because it offers travel-system convenience and allows baby to move from car to stroller without being unbuckled.

How long should my baby stay rear-facing?

Many state laws require rear-facing until at least age two, but requirements vary by state. Safety experts generally recommend keeping children rear-facing as long as possible, until they reach the rear-facing height or weight limit of their car seat. Seats like the Nuna RAVA Next and Nuna EXEC Next support extended rear-facing use up to 50 pounds.

Which Nuna car seat is best for extended rear-facing?

The Nuna RAVA Next and Nuna EXEC Next are both strong choices for extended rear-facing because they can be used rear-facing up to 50 pounds. The Nuna REVV Maxx also supports rear-facing use, but has lower rear-facing weight limits than the RAVA Next and EXEC Next.

When can I switch my child to forward-facing?

Keep your child rear-facing until they exceed the rear-facing height or weight limits listed in your car seat manual. In addition to following any state requirements, always follow your specific car seat’s age, height, weight, and installation guidelines before switching to forward-facing.

How long does my child need to stay in a 5-point harness?

Most forward-facing harness systems accommodate children up to about 49 inches or 65 pounds. Keep your child in a 5-point harness until they have truly outgrown the harness height or weight limits. Do not rush the transition to a booster seat if your child still fits safely in a harnessed car seat.

When can I transition my child to a booster seat?

Most booster seats require a minimum weight of 40 pounds, which often happens around age four, but many children should remain in a harnessed seat longer. A child should be mature enough to sit properly for the entire ride before transitioning to a booster. If your child is outgrowing their convertible car seat but you want to keep them harnessed longer, a harness-to-booster seat like the Nuna LUMN can be a smart next step.

What is the difference between the Nuna LUMN and Nuna AACE?

The Nuna LUMN is a harness-to-booster car seat. It starts as a forward-facing seat with a 5-point harness and later converts to a booster. The Nuna AACE is a dedicated booster seat for children who are already ready to ride using the vehicle seat belt.

Which Nuna car seat is best for compact cars?

The Nuna RAVA Next is often a strong choice for compact vehicles because of its compact rear-facing fit. It can also be helpful for taller parents who need more front-seat leg room while keeping their child rear-facing.

Which Nuna car seat is best for tall SUVs?

The Nuna REVV Maxx is a great option for taller SUVs because the rotating seat makes it easier to lift your child in and out without leaning deeply into the back seat. It can also be helpful for grandparents, caregivers, or parents with mobility limitations.

Which Nuna car seats fit 3 across?

The Nuna RAVA Next, Nuna EXEC Next, Nuna LUMN, and Nuna AACE are designed to fit 3 across in many midsize vehicles. Fit can still vary by vehicle, seating position, and the other car seats being installed, so it is always best to confirm your specific setup before purchasing.

Do Nuna car seats recline?

Yes. Nuna next-stage car seats, including the REVV Maxx, RAVA Next, EXEC Next, LUMN, and AACE, offer multiple recline positions to help support proper riding angles and improve comfort for naps on the go.

Are Nuna car seats FAA certified?

Some Nuna car seats are FAA certified for aircraft use in harness mode, while others are not. The Nuna RAVA Next, EXEC Next, and LUMN are aircraft certified when used in harness mode. The Nuna REVV Maxx is not FAA certified, and booster seats like the Nuna AACE are not used on airplanes because they require a lap-and-shoulder belt.

Does Nuna use flame retardants?

Nuna car seats are made without added flame-retardant chemicals. Nuna uses carefully selected materials designed to meet safety standards while giving parents a cleaner-materials option.

Which Nuna car seats are GREENGUARD Gold Certified?

The Nuna car seats featured in this guide are GREENGUARD Gold Certified, meaning they have been tested for low chemical emissions to help support healthier indoor air quality around your child.

Are Nuna car seats safe?

Yes. Nuna has a strong reputation for safety, combining thoughtful engineering, energy-absorbing materials, steel-reinforced components, and user-friendly installation features across its car seat lineup. As with any car seat, the safest option is one that fits your child, fits your vehicle, and can be installed and used correctly every time.

Are Nuna car seats worth the price?

For many families, yes. Nuna car seats are designed with advanced safety features, premium comfort, durable materials, intuitive installation, and long-term usability. While they are an investment, many parents find the ease of use, comfort, and quality worth the price.

What is the best Nuna car seat?

The best Nuna car seat is the one that fits your child’s current age, height, and weight, installs properly in your vehicle, and matches your family’s daily routine. Choose the Nuna REVV Maxx if rotation is your top priority, the Nuna RAVA Next if you want a compact convertible seat with extended rear-facing use, the Nuna EXEC Next if you want one long-term all-in-one seat, the Nuna LUMN if you want to keep an older child harnessed longer, and the Nuna AACE if your child is ready for a dedicated booster.

Which Nuna car seat should I choose if I want one seat to last the longest?

The Nuna EXEC Next is the best Nuna car seat for families who want one seat to cover the most stages. It transitions from rear-facing to forward-facing to booster mode, making it a strong long-term investment.

Do Nuna car seats expire?

Yes. Nuna car seats have expiration dates, and the exact expiration should be checked on your specific seat and in your user manual. Never use a car seat past its expiration date.
