  • Easy to Install

    One of the easiest to install seats ever. Love that we can sit 3 kids across in a sedan's back seat.

    We have several of these for our kids. We are able to fit three car seats across in a sedan. Very sturdy, easy to buckle, look nice, comfortable, and slim!!!

  • sturdy

    I love this. It's very sleek - I didn't want a bulky car seat that would take up 1/2 of the backseat row. Very tough construction, but very soft inside. My little girl loves it! Also, the seat folds up for easier transfer from car to car or storage.

  • Love!

    Wouldn't buy anything else! It's slim and not so big and bulky like most. My husband wishes he had one for his truck instead of the other we had bought.
