      Facile d’installation

    • Great value for money

      from Hamilton, ON on May 3, 2019

      This forward facing car seat does everything I need it to do for my 3 year old. It’s half the price of most other car seats and it will last my son until he doesn’t need a booster anymore. Was relatively easy to put together out of the box and fits well in our van. I plan on buying another seat for our other car when it goes on sale again.

    • Good seat, bad anchor straps.

      from Calgary, AB on April 17, 2019

      The seat is a good seat for the price. Bottom anchors are a hook type, more difficult than button-release. Upper anchor strap comes from two points but shortly goes to one strap. I was unable to use in my Jeep as the head rests are attached to the seat. The strap from the two points was too short to go over the seat. Using the single strap going over top of the headrest would have risked it sliding off to one side. Material was good. The instructions are in a compartment under the bottom of the seat, not intuitive to find. The instructions aren't easy to read, but are understandable if you have installed a car seat before .
