About Safety 1st Air Protect Technology

Side impact car crashes account for 1 in 4 of all car crashes and account for 1 in 3 child fatalities—all caused by head trauma inflicted during the accident.  With this in mind, Safety 1st created its new Air Protect Technology.  Safety 1st engineers simulated violent side impact car crashes and developed Air Protect, which is a dual system designed to protect your child during a side impact collision.  In Air Protect’s first defense, it immediately shields your child’s head from impact during a collision and then afterwards allows air to escape from the headrest, channeling crash energy away from your child.

Cost: The Safety 1st onBoard 35 Air Protect Infant Car Seat retails for $148.99-$179.99.  The SE model retails for $189.99-$205.99.

Safety 1st onBoard 35 Air Protect Infant Car Seat

The Safety 1st onBoard 35 Air Protect infant car seat has received a rating of 4.5 out of 5 stars from users at,, and

Users  really love the Safety 1st onBoard 35 Air Protect infant car seat and have posted many, many rave reviews and very few negative ones.

One of the biggest pluses seen in review after review for the Safety 1st onboard 35 Air Protect infant car seat is how easy the installation of the seat is.  Users can’t believe how simple it is to install this infant car seat and they say the latch system on this seat is super easy to use. The seat comes with a slide spout feature that helps to correctly angle the seat during installation and you won’t need a rolled up towel or noodle like you do when installing other infant car seats.

Another positive for this car seat that has gotten parents really excited is the extended length of the seat which allows children to actually remain in the infant car seat until they reach the seat’s 35 lb weight limit.  Many parents have complained about other infant car seats saying their child outgrew the seat well before the weight limit for the seat.  The baby could just no longer physically fit in the seat.  This seems not to be a problem with the new extended length Safety 1st seat.  Users are simply thrilled that this seat will outlast the lifespan of the other infant car seats on the market.

It Keeps Getting Better

Continuing with the positive features of this seat, users report that the provided extra head and hip pillows hold baby very securely in the seat and they can be removed as the baby grows.  Babies seem extremely comfortable in this infant car seat and users say the seat feels like superb quality.  Also, unlike many other infant car seats on the market, this car seat is extremely lightweight (when the baby is not in it) and is easy to carry until the baby becomes too heavy.  Most users agree that the seat fits in most cars without an issue (meaning it doesn’t push the front passenger seat forward) and the seat cover is extremely soft and easy to wash.

The seat’s carry handle is very sturdy and it has a comfortable grip area. The sun canopy that comes with the seat is a good size—but can block the driver’s view if fully extended in the car.  The infant seat is easy to pop in and out of the car seat base and it clicks in the base quietly so you won’t wake a sleeping baby.

And, most importantly, this is a very safe infant car seat and has received top ratings from Consumer Reports in crash safety tests!

Safety 1st onBoard Air Infant Car Seat Negatives

On the down side, some users complain that the Safety 1st onboard Air Protect 35 infant car seat is just too big and won’t fit in all cars (so test the seat in your car before purchasing) and a few users complain that the air filled extra head protection is too high up on the seat and won’t help a small baby in the event of an accident.  They wish this feature was adjustable.  Some also say the chest clip is too big and the canopy is too noisy when adjusted.

Low Toxicity For Car Seat Material

****Low Toxicity for One Safety 1st onBoard 35 Models:  New studies have been released showing the levels of toxins and chemicals used in different car seat fabrics and fabric dyes.  This new study advises staying away from car seats with high levels of toxic chemicals used in the production of these colors.  Most car seats on the market today have received a medium rating for levels of chemicals, with a few ratings of the scary high for some car seat fabrics.  However, the Safety 1st onBoard 35 infant car seat 2011 model has 1 fabric choice that has been rated Low for toxic chemicals is therefore one of the safest car seat fabric picks you can make (and this seat has no fabrics in the high rating).  The one Safety 1st onBoard 35 infant car seat low toxicity color to choose is: McKenna.
