Shop smart and get two seats in one with the Safety 1st Boost Air 100 Belt-positioning Booster Car Seat. The perfect booster for growing kids it comes with the Air Protect™ system which works to protect your child in two vital ways. In a side impact collision, Air Protect™ immediately safeguards your child by diminishing the forces if the crash. In a second layer of defense, the system allows air to escape from the headrest: channelling more crash energy away from your child. It is this double layer of protection that makes Air Protect™ technology unique.
The Boost Air 100 is designed for children who weigh 40-100 pounds and are 40 to 57 inches tall and just adapts to your growing child. It has an easy-to-adjust headrest that gives a custom fit to your child. When they're ready, the back removes, and you have a backless booster that's easy to transport and stores easily in the trunk when not needed. In either mode, the cup holder holds a drink or snack during the ride or hides away inside the seat when not needed.
