DESC: The new Parkway booster is one of the only boosters to offer True Side Impact Protection. The EPS foam-padded headrest and side "wings" aren't just great for naps, they're engineered to provide vital protection to your child in the event of a side-impact crash. The Parkway's headrest is easy to adjust with one hand, and allows the seat to grow up with your child - all the way up to 60" tall.
