Is this product the right choice for you?
Honestly, no pressure. Decide once — and get it right.
✅ Best suited for
The car seat is designed for newborns and infants from birth up to 13 kg (40–87 cm), who spend most of their time in the car peacefully sleeping. A recline of up to 157° enables a lying position and proper spine support while driving, while the built-in side protection provides extra safety in the event of a side impact. It's a great fit for you if you're looking for a lightweight yet safe solution for your first outings with your newborn, as well as for you if you already own or are planning to purchase the Nuna Next 4-in-1 modular system.
🤔 Less suitable if
The seat is designed exclusively for rearward-facing installation and is suitable up to a maximum of 87 cm or 13 kg, so it's not suitable for older or taller children. To fully take advantage of the True lock Isofix system with a support leg, you'll need to purchase the Isofix base Base Next separately — otherwise, installation is only possible using the car's seat belt.
