Who the All4Stages Slim Plus Canopy 4-in-1 Convertible Car Seat fits

This seat covers 4 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.

Rear-facing harness4 to 40 lb · 17 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 harness30 to 65 lb · 35 to 49 in · from 2 years
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.
High-back booster40 to 100 lb · 44 to 57 in · from 5 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 120 lb · 44 to 60 in · from 5 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 All4Stages Slim Plus Canopy 4-in-1 Convertible Car Seat installs

Harness
No-rethread harness. 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 25.2 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.
  • Aircraft certification is printed on the seat’s own label; check before you fly.

Is the All4Stages Slim Plus Canopy 4-in-1 Convertible 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; Evenflo 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 Evenflo so you hear about the next one.
