A rotating convertible car seat with 2 modes: rear-facing harness 5 to 30 lb, 18 to 34 in; forward-facing harness 30 to 40 lb, 34 to 43 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 2 stages, and a child has to meet every limit of the stage they are in. Nuna gives it a 10-year life from the date of manufacture, so check the date label before using a hand-me-down.

| Mode | Child weight | Child height | Minimum age | Conditions |
|---|---|---|---|---|
| Rear-facing harness | 5 to 30 lb | 18 to 34 in | Not published | Birth to 2+ years; vehicle belt or lower anchor 5-30 lb |
| Forward-facing harness | 30 to 40 lb | 34 to 43 in | 2 years | At least 2 years old; lower anchor installation limited to 35 lb; vehicle belt to 40 lb |
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 18.5 in at its widest, measure your back seat before counting on three across. It weighs 29.7 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.
