The Baby Jogger City Turn Convertible Car Seat features a secure rotating mechanism that allows you to turn the seat 180 degrees with one hand while in rear-facing mode. The unique patented rotation brings your child 10 inches closer to you, and helps you maintain a more upright posture when lifting your child in and out and buckling them into the car seat. The seat smoothly rotates with one hand, then audibly clicks into place for assurance that it is safely secured.
