Booster by Graco. Details:The Graco 4Ever DLX Grad 5-in-1 Car Seat is designed to keep your child safe from infancy to preteen years.

The space-saving design is 10% slimmer at the cup holders compared to the 4Ever DLX, giving your child room to grow without crowding your back seat.

It even allows usage with two kids at once with its removable seat-belt trainer.
