Safety 1st Complete Air Review

(Last Updated On: )

The Safety 1st Complete Air is a nicely priced, lightweight convertible seat that fits in some narrow spaces, but can take up quite a bit of room front to back.

  • Forward facing height limit: 29-49″ (older versions may have a 34″ minimum and/or a 52″ maximum; check your manual )
  • Shell height: 27″
  • Lowest harness position: 10″
  • Highest harness position: 17″

  • Lower anchor weight limit: 48 lbs.

When this seat was first released, the seat required a rear-facing angle of 45 degrees.  This made it pretty tricky to install and resulted in the seat taking up a lot of space front-to-back. If the seat was installed at this angle, the passenger in front would have almost no leg room!  Some versions of the Complete Air now have two lines that allow for a more upright installation for children over 22 lbs, which can make a big difference in back seat real estate.

However, without any infant padding, and with a 10″ lowest harness slot, this seat wouldn’t work for infants younger than 6-9 months. Height-wise, this seat is outgrown rear facing when the child reaches 40″ or the top of the child’s head reaches the top of the shell.

The Complete Air features a no re-thread, continuous loop harness.  The no re-thread harness means that you can adjust the height of the harness without uninstalling the seat.  Continuous loop means that the harness is one big loop.  While this can be confusing at first (check out our article about these harnesses), this feature can make it easier to load a kiddo who likes to struggle their way into the car seat so this can be an advantage.

6-year-old model has some room to grow


Forward facing, the Complete Air has 17″ top shoulder slots.  This means that many children would outgrow this seat forward facing around 5-6 years old so that makes it a nice option to get a child to booster age.


At around $150, the price makes this seat an attractive option for older infants through booster-aged children.
