Who the KidFit Zip Air Plus Booster Car Seat fits

This seat covers 2 stages, and a child has to meet every limit of the stage they are in. Check the date label on the shell before using a hand-me-down; every seat has an expiry.

High-back booster40 to 100 lb · 44 to 57 in · from 4 years
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.
Backless booster40 to 110 lb · 44 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 KidFit Zip Air Plus Booster Car Seat installs

Lower anchors
Quick Release LATCH. Check your vehicle manual for which seating positions have anchors, and switch to the seat belt once the child passes the anchor weight limit in the manual.
Recline
2 recline positions. The recline angle is what keeps a young baby’s airway open, so set it before tightening the install.

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 17 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 11 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.

What features does the KidFit Zip Air Plus Booster Car Seat have?

Is the KidFit Zip Air Plus 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.
  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 Chicco so you hear about the next one.
