Marathon Booster Seat
A look at what is currently available on eBay
Which carseat to choose?
My 6-month old son is approximately 20 pounds. We are looking to switch from the infant carrier to the convertible car seat. The Britax Roundabout is rated to 40 pounds, but we are afraid he may outgrow this weight-wise before he is ready for a booster-seat age-wise. The price and size difference between the Roundabout (40 pounds) and Marathon (65 pounds) is considerable. These are the only seats that fit him comfortably and with great safety ratings.
Definitely go with a seat that harnesses past 40lbs. Children outgrow seats by height before weight. Most 40 lbs seats are outgrown before a child is truly mature enough and big enough for a booster with seatbelt. 4years AND 40lbs is the bare minimum for booster with seatbelt.
We have 2 Britax Marathons and love them!
