ISOFLEX Flexible Lower Connection System

Secures the booster seat to the vehicle in seconds from either side of the booster seat with two clicks and a pull. ISOFLEX prevents the booster seat from becoming a projectile when not in use, and stabilizes it during a crash.

Base with SafeCell Technology

Designed to keep your child safe and secure in a crash by compressing and significantly lowering the center of gravity, reducing the forward movement of the car seat.


Works with the vehicle safety belt to prevent the child from sliding under the lap-belt portion of the safety belt (submarining) during impact, thus minimizing the risk of abdominal injury.

We love this seat!
We bought this car seat for our 6 year old son. He loves it! It's a bit heavy and awkward to handle when changing cars because the back always seems to snap back, but otherwise it is very easy to install. The fabric is easy to wash, and my son, who usually runs hot, doesn't complain about sweating in this seat, even after taking a nap.

Worth the money for the safety features
After careful selection we decided on this booster for our daughter. We love the secure guard-we feel this is much safer. It seems like such a big step to go from car seat to booster. The Britax Parkway makes this step a little less scary for parents and child. This seat had all of our requirements, high back, latch, side protection with the added bonus of secure guard. The fabric is washable and our daughter finds it very comfortable and the seatbelt is positioned perfectly.
