The American Academy of Pediatrics recommends children ride rear-facing until at least 2 years of age. Extend2Fit features a 4-position extension panel that provides 5” of extra legroom allowing your child to ride safely rear-facing longer. The seat can be used rear-facing from 4-50 lbs. and forward-facing from 22-65 lbs. 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. For additional leg room squeeze the adjustment handle and pull the extender out. Metal and plastic parts may be cleaned with mild soap and cool water.
