Easy to install. I wanted a car seat that I could adjust the shoulder harness on without rethreading and one that my grandson could climb into on his own.
Britax - Grow With You Harness‐2‐Booster
This was one of afew chairs and is "the most comfortable", Notably more padding . Downside- padding makes noise, especially when driving empty. The extra storage/drink holders a big plus. Little Canadian also delivered on the promise for expedited shipping- chair arrived impressively quickly.
Excellent quality easy to install. Very fast shipping
Fantastic upgrade from our Britax Marathon. My daughter especially loves the cup holders. Comfortable & easy to install. Glad when my daughter is ready to give up the 5 point harness that the seat is well anchored instead of just relying on the shoulder harness.
Great product! Safe easy to install and really comfortable. My daughter loves it and so do I
