Prices and purchase links will return when a fresh, eligible listing is available. The review and manufacturer sources remain available below.
This seat covers 2 stages, and a child has to meet every limit of the stage they are in. 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 |
|---|---|---|---|---|
| High-back booster | 40 to 100 lb | 44 to 57 in | 4 years | Product page and manual: at least 4 years old and able to sit still in the seat belt. |
| Backless booster | 40 to 110 lb | 44 to 57 in | 4 years | Product page and manual: at least 4 years old and able to sit still in the seat 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 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 10 lb, which matters if you will move it between cars or carry it through an airport.
Seascape.
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.
