Britax Frontier Booster Car Seat

The Britax Frontier Car Seat is one of the best higher weight five point harnessing seats on the market and is great for heavier kids who are not mature enough for a belt positioning booster seat. It is expensive, but I have found Britax seats to be worth the extra cost time and again. The Frontier can be a bit difficult to install, and once its in the car, I really don't recommend taking it out unless necessary. Its also heavy and is a BIG seat...it would be very difficult to fit three carseats across a seat with the Frontier in the mix. However, this is one of the best seats out there for forward facing toddlers and will last a very long time.
