Designed for big kids who are ready for the next step, the UPPAbaby® Alta V2 booster seat pairs elevated safety with a tailored, modern look. Thoughtfully engineered to position the vehicle seat belt properly across the shoulder and lap, it helps support growing bodies from carpools to road trips. Energy-absorbing foam and side impact protection work together to add an extra layer of security, while the open belt guides make self-buckling easier and more intuitive. Rigid LATCH attachment keeps the seat stable, even when unoccupied, and the slim profile fits seamlessly alongside other passengers.
