Children are safer riding rear-facing and should ride rear-facing as long as possible, until they reach the maximum rear-facing height or weight rating for their car seat. Extend2Fit features a 4-position extension panel that provides 5" of extra legroom allowing your child to safely ride rear-facing longer. The seat can be used rear-facing from 4-50lb and forward-facing from 22-65lb. The seat features Simply Safe Adjust which allows you to adjust the height of the harness and headrest as your child grows. InRight LATCH for a one-second LATCH attachment and Fuss Free harness storage which holds the buckle out of the way, so it's easy to get baby in and out.
