The Safety 1st Grand 2-in-1 Booster Car Seat is a flexible option designed to grow with your child, working as a forward-facing harness seat for kids weighing 30 to 65 pounds, then converting to a belt-positioning booster for those up to 100 pounds. This adaptability makes it a good choice if you want a seat that lasts through different stages. It supports children up to about 30 inches tall in harness mode, which fits many average-sized toddlers.

This booster seat is a practical, easy-to-use choice for families wanting a seat that adapts from a harness to a belt-positioning booster, offering solid basic safety and convenience features.
