An infant car seat with one mode: rear-facing infant 4 to 30 lb, 16 to 29 in.
Nuna lists this seat on its US site. Buy from Nuna or an authorized retailer, and confirm the exact model number before you buy.
This seat covers one stage. Check the date label on the shell before using a hand-me-down; every seat has an expiry.

| Mode | Child weight | Child height | Minimum age | Conditions |
|---|---|---|---|---|
| Rear-facing infant | 4 to 30 lb | 16 to 29 in | Not published | Rear-facing only; installs without a base using integrated pipaFIX rigid latch or vehicle belt |
A child must meet every limit for the mode they use. The labels on your seat and its manual are the final word.
Every install is a fit between one seat and one vehicle. Read both manuals, and use a free inspection station if anything is unclear.

At 17.5 in at its widest, this seat is one of the narrower ones in its class and is a candidate for three across in many mid-size cars. It weighs 7 lb, which matters if you will move it between cars or carry it through an airport.
No campaign in the current NHTSA child-restraint data names this model family, and I have not run a separate review for it. Check your seat’s model number and date of manufacture before use.
