NHTSA lists a campaign naming this model family (22C002000). I pause shopping links until I have read the campaign and checked which build dates it covers.

Who the Olli fits
This seat covers one stage. Clek gives it a 9-year life from the date of manufacture, so check the date label before using a hand-me-down.
Backless booster40 to 120 lb · 40 to 57 in · from 4 years
Only the base is left, so the vehicle seat has to support the child’s back and head, and the belt guide sits at the hip.

How the Olli installs
Rigid LATCH
Rigid LATCH. Rigid connectors click straight onto the vehicle's lower anchor bars, which removes the strap slack that causes loose installs.
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 18 in at its widest, measure your back seat before counting on three across. It weighs 5 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.
Not certified for aircraft use: plan on gate-checking it or using a different seat to fly.

Is the Olli recalled?
NHTSA currently lists one campaign naming this Clek family: 22C002000. 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 4 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.
