NHTSA lists a campaign naming this model family (21C005000). I pause shopping links until I have read the campaign and checked which build dates it covers.
Specifications checked against Clek’s US site and manual on . Not hands-on tested. How I research
Who the Foonf fits
This seat covers 2 stages, and a child has to meet every limit of the stage they are in. Clek gives it a 9-year life from the date of manufacture, so check the date label before using a hand-me-down.
Rear-facing harness14 to 50 lb · 25 to 43 in
The child faces the back of the car, which keeps the head, neck and spine supported in a frontal crash. Keep this mode as long as the child fits it.
Forward-facing harness26.5 to 65 lb · 30 to 49 in · from 12 months
The child faces forward in the seat’s own harness. Use the top tether every time, and stay in the harness until the child outgrows it.

How the Foonf installs
Rigid LATCH
Rigid LATCH (forward-facing). Rigid connectors click straight onto the vehicle's lower anchor bars, which removes the strap slack that causes loose installs.
Belt lock-off
Rear-facing lock-offs. A lock-off clamps the vehicle belt so you do not have to switch the belt's retractor into its locked mode.
Harness
6 harness heights. Check the harness height at each growth spurt: at or below the shoulders rear-facing, at or above them forward-facing.
Every install is a fit between one seat and one vehicle. Read both manuals, and use a free inspection station if anything is unclear.
Will it fit your car?
At 16.9 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 38 lb, which matters if you will move it between cars or carry it through an airport.
Check your vehicle manual for lower anchor positions and any head-restraint rules.
Rear-facing seats need front-seat room: try the install behind the driver before you commit.
Certified for aircraft use, so it can travel as a seat rather than checked baggage.
The outlet listing "foonf - clearance" (Date of Manufacture: 2026, final sale) states forward-facing weight 22-65 lb; the main Foonf page and the US manual dated October 2025 state 26.5-65 lb.
When they differ, follow the manual and the labels on your seat.
Is the Foonf recalled?
NHTSA currently lists one campaign naming this Clek family: 21C005000. A campaign names a family, not always every build, so check your seat’s model number and date of manufacture against the campaign itself.
I have not reviewed these campaigns for this model yet, so shopping links stay paused here.
Weigh and measure your child. The limits above are the manufacturer’s, and a child has to meet all of them for the mode they will use.
Confirm the exact version. Colors, retail exclusives and model numbers change limits more often than you would expect; Clek lists 9 colors of this seat.
Read the manual before you buy, not after. It is linked above and holds the fit rules, the install methods and the expiry.
Check recalls by model number and date of manufacture, and register the seat with Clek so you hear about the next one.
