Who the RodiSport Booster Car Seat fits

This seat covers 2 stages, and a child has to meet every limit of the stage they are in. Maxi-Cosi gives it a 10-year life from the date of manufacture, so check the date label before using a hand-me-down.

The seat’s own back and belt guide route the vehicle belt across the shoulder, and the sides give the child something to lean on when they sleep.

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 RodiSport Booster Car Seat 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?

Maxi-Cosi does not publish a width for this seat, so measure your back seat and compare it with the seat in a store before buying.

  • 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 RodiSport Booster Car Seat recalled?

No campaign in the current NHTSA child-restraint data names this model family, and I have not run a separate review for it. Check your seat’s model number and date of manufacture before use.

Before you buy

  1. 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.
  2. Confirm the exact version. Colors, retail exclusives and model numbers change limits more often than you would expect; Maxi-Cosi lists 3 colors of this seat.
  3. Read the manual before you buy, not after. It is linked above and holds the fit rules, the install methods and the expiry.
  4. Check recalls by model number and date of manufacture, and register the seat with Maxi-Cosi so you hear about the next one.
