Joie Baby Bay Latch SI Plus Car Seat vs Joie Latch SI 3-in-1 Harness Booster

Both seats are the same Joie 3-in-1 shell with 15 headrest positions, 4 seat depth settings and identical dimensions and weights. The Bay Latch SI Plus adds a removable 7-position footrest, ventilated seat back, AutoClick magnetic chest clip and dishwasher-safe cup holders. The Latch SI covers the same harness, highback and backless ranges without those extras. Buy the Bay Latch SI Plus for a younger child who will use harness mode for years and wants leg support and airflow. Buy the Latch SI if the child is close to booster age and you don't need the footrest.

• Choose the Joie Bay Latch SI Plus if your child is still in harness mode and you want the footrest, ventilated back and magnetic chest clip for long rides.
• Choose the Joie Latch SI if you want the same 3-in-1 fit and safety shell without paying for comfort extras your older child won't use.
