Our comments: Designed for school-age kids who are at least 40 lbs., 44″ tall, and mature enough to sit properly in a booster seat. These versatile Britax boosters will grow with your older child.

Graco TurboBooster Grow with RightGuide Seatbelt Trainer
Specs & Features: Main booster is rated for kids 40-100 lbs.; 43-57″ tall, and at least 4 years old. RightGuide Seatbelt Trainer is rated 50-120 lbs.; at least 43″ tall; lower LATCH anchor connectors on highback booster; EPS foam in headrest; dual cup holders; 7-position height adjustment
Drawbacks: None that we can think of!
Our comments: Designed for school-age kids who are at least 40 lbs., 43″ tall, and mature enough to sit properly in a booster seat. This innovative new booster is tall and we love the seat-within-a-seat feature which can be separated to accommodate two kids at once! The compact RightGuide Seatbelt Trainer pops out of the main seat so you can use it to seat a second child (who weighs at least 50 lbs.) for carpooling, playdates, etc., or throw it in a backpack when traveling. The RightGuide Seatbelt Trainer is also perfect for many tweens who just need a small boost in the car to achieve proper fit from the adult seatbelt. Full review coming soon!
