We need to have an emergency booster around for my oldest. We have him harnessed in a Frontier or Radian in our cars, but if he goes with my SIL, she needs a seat and I'm comfortable with him in a booster at his age and size.
Which booster is the easiest to use and most comfortable? I like the latch with the Affix so the seat doesn't slide around but I don't know how important that is.
