How do you convert car seat into just a booster?

1 comments:
Mr. Anderson
February 17, 2025

The Baby Trend Hybrid 3-in-1 car seat converts into a booster seat by transitioning through its three stages:

1. Harness Booster Mode: Used with the 5-point harness for children weighing 30–50 lb and 29”–48” tall.
2. High-Back Booster Mode: The internal harness is removed, and the seat is used with the vehicle’s seat belt for children weighing 40–100 lb and 38”–50” tall.
3. Backless Booster Mode: The backrest is removed, leaving only the base, and it is used with the vehicle’s seat belt.

Ensure proper installation by following the car seat and vehicle owner's manuals.
