FYI: The onSide Air appears to be discontinued. We have seen it still for sale online, however. Below is an archived review.
Type: Convertible seat.
Limits: 5 to 40 lbs. rear facing, 22 to 40 lbs. forward facing.
NHTSA ease of use rating: Front Facing: Four out of five stars. Rear Facing: Three out of five stars.
Pros: Side impact protection. Under $100.
Cons: Only works to 40 lbs. front facing.
Comments: When they debuted the Safety 1st onSide Air back in 2010 it positioned it as a more affordable alternative in its Air Protect line. While it works to the same amazing 40 lbs. rear facing as the $125-$150 Complete Air, the onSide Air tops out at only 40 lbs. forward facing.
The attraction here is the price: a seat that can be used rear facing to 40 lbs. AND costs under $100. Plus you get the Air Protect side impact technology, which deploys in a crash to better protect a baby’s head.
Parent reviews on this seat have been positive—this seat works well in smaller vehicles, which can be a challenge for other car seats. A few dissenters had issues installing this seat securely when rear-facing.
This seat earned a “basic” rating for crash protection in the latest testing by Consumer Reports.
