This compares published manufacturer specs — not safety or fit advice. The seat's manual, your vehicle's manual, NHTSA's tools and a certified CPST are the fit-and-safety authority; always check them before installing.

Nuna RAVA: Convertible (rear-facing → forward-facing harness; no booster mode). Manual gives ONE overall height ceiling for the whole seat — 49″ (124 cm) or less — not split by mode, so no per-mode height range is published. Forward-facing recommended at 2 years or older. Do not use if more than 10 years old (checked against the stamped manufacture-date label).
WAYB Pico: Forward-facing harness only, age 2+. Limits depend on the manufacture date on the label under the seat: seats made on or after June 30, 2025 are for children 26.5–50 lb and 33.5–45″ (shown here); earlier seats are for 22–50 lb and 30–45″. Useful life is 7 years from date of manufacture on both versions.
That is the record of the brand — not a verdict on these models. A recall names specific models and manufacture-date ranges, and a seat missing from the record is not "recall-free": check nhtsa.gov/recalls with the model and date of manufacture on your seat's label.
