👍👍👍
We purchased this as a second base for our baby’s car seat so we’d have a base in each of our cars. It’s a great quality base that is user friendly. It’s easy to install into both of our cars and easy to install the car seat into. The leg feature provides extra safety and security for our baby girl while driving in the car. Very pleased with how it fits and functions in both our Prius and Pathfinder.

Great base
So easy to install and doesn’t shift or move, making for a safe and secure ride for baby. Very lightweight and easy to remove if needed compared to other car seats

Perfect for our Second Car
The perfect addition to our second car so we don’t have to stay the seat in with the seatbelt! Extremely easy to install with the new click system … we didn’t have to pull the straps and try to tighten! And the added load let for safety gives us such a piece of mind while traveling with our little peanut!
