DS is 4.4 years old, 43 inches tall, 16 inches hip to shoulder and 38 lbs. I am looking for a booster/ 5 pt. harness convertible seat for my mother's car. This will be the only car seat in her car (a Toyota Avalon). This will only be for occasional use (not daily) so I don't want to spend the $ for the Britax Parkway (or Frontier) until I have to for my car. He is the baby in our family so this is it for the car seats.
I was looking at the Evenflo Maestro but the reviews said that it is a short booster. I would like to be able to buy the one seat for her car that will last until DS is 7.
So, two questions... what would you recommend for my mother's car?
What would you recommend when DS outgrows the Britax Boulevard- the Parkway or Frontier?
