Both are all-in-one car seats — here are their published manufacturer specs side by side.
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.

Maxi-Cosi Magellan LiftFit: All-in-one (rear-facing → forward-facing harness → high-back belt-positioning booster; no backless mode found in manual). FAA-certified for aircraft use with the internal harness (per manual). Forward-facing requires at least 1 year old. Useful-life figure (12 years) was on an image-only page of the manual PDF not machine-readable in this environment — cross-verified via safeintheseat.com, a CPST-authored car-seat safety review site, whose independently quoted RF/FF/booster numbers matched the manual's own printed table exactly.
Nuna EXEC: All-in-one (rear-facing → forward-facing harness → high-back booster; no backless mode found in manual). Manual gives ONE overall height ceiling for the whole seat — 57″ (145 cm) or less — not split by mode. Forward-facing recommended at 2 years or older; booster at 4 years or older. Do not use if more than 10 years old (printed number, per manual).
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.
