Car Seat Buying Kits 2.0 launching soon. Join the waitlist for introductory pricing!

Use Caution if:

You have a larger percentile child.

The highest harness height is only 15.5″ tall, so if you have a child with a long torso, this is probably not the best seat for you. This is relevant because you need the harness to come from even with or just above their shoulders when forward-facing. Many other seats in this category have harness heights that are 17+ inches. The highest belt guide position on this seat is only 17, so it’s not long-lasting in the high-back booster mode either. 

You need to fit 3 across.
