Clek Foonf vs Maxi-Cosi Pria Max

Both are convertible 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.

How they differ

• the Clek Foonf is listed narrow (roughly ≤17″) for fitting three across a back seat; the Maxi-Cosi Pria Max isn't listed narrow
• the Clek Foonf lists extended rear-facing (a higher rear-facing weight limit, ~40-50 lb); the Maxi-Cosi Pria Max doesn't
• the Maxi-Cosi Pria Max is FAA-approved for aircraft; the Clek Foonf isn't (harnessed seats can be FAA-approved; boosters never are — a plane has no shoulder belt)

Published limits

Clek Foonf: Rear-facing → forward-facing convertible, no booster mode. Forward-facing recommended at 2+ years (1 year minimum). This manual PDF bundles two printed revisions — Feb 2024 (forward-facing min 22 lb) and Oct 2025 (forward-facing min 26.5 lb); used the most recent Oct 2025 revision (rev FO25USH2), the first table in the document.

Maxi-Cosi Pria Max: 3-in-1 all-in-one (rear-facing → forward-facing harness → high-back belt-positioning booster; no backless mode found in manual — the site currently lists this model's stage as "convertible" only, but the manual confirms a booster mode too). Forward-facing requires at least 1 year old.

Printed verbatim in the manufacturer's manual (Clek Foonf US Owner's Manual (Oct 2025, rev FO25USH2) · Maxi-Cosi Pria Max 3-in-1 (Item CC208) US Owner's Manual); “—” = not published for that mode, “not yet sourced” = we haven't read that manual yet, not that the seat has no limit.

Recall record

Clek — 4 on NHTSA's record · Maxi-Cosi — 6 on NHTSA's record.

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.
