The seat does'nt even move one milimeter. Excellent head and side support and the adjustment belt is super easy to use. I love the fact that when the seat will be forward facing, that my child will be able to stay in the same seat up to 65lbs. I bought my seat at Traveling Tikes whom is offering the Britax Marathon with shipping for a very low price. GREAT SEAT! GREAT PRICE. Is this product review negative?
