    • Pleased with booster seat

      from Fredericton, NB on April 12, 2019

      Very easy to assemble. Seems to be very sturdy. 5 year old Granddaughter reports that it is very comfortable every time she gets buckled in. Overall very pleased. This is the second one I purchased.

    • Great!

      from Dieppe, NB on November 20, 2018

      I've been using this seat for a year now and I still love it. Wasn't that difficult to put together. The buckle is a little short and I thought it would be an issue, but it hasn't been. The straps adjust really easily. I am about to buy a second one to fit in out other vehicle.

    • We love it! 5*

      from Dollard-des-ormeaux, QC on May 20, 2017

      w purchased the Defender because all the reviews we read say that it is a very safe car seat. Turns out it is also very comfortable. When |I saw that I had to assemble the back I was a little nervous but the instructions were terrific and it was actually very easy to do.
