Graco AFFIX Highback Booster Car Seat with Latch System, in Atomic

Convertible Safety

Graco’s AFFIX Highback Booster Car Seat with Latch System, in Atomic, helps keep your growing child safe. The American Academy of Pediatrics (AAP)—one of the most respected resources in child safety—recommends that children 4 feet 9 inches tall or under should ride in a belt positioning booster seat. In support of the AAP recommendation, the AFFIX Highback Booster Seat with Latch keeps your “big kid” riding in high back booster seat mode from 30 – 100 lbs. and from 38 – 57 inches tall. Then, when your child is ready, it converts to backless mode for children 40 – 100 lbs. and from 40 – 57 inches tall. It’s like having two booster seats in one!

Easy Installation

Installation is a snap with the AFFIX: you can install this high back car seat in just seconds with just one hand, thanks to the unique one-hand, front-adjust LATCH system. Since it has the front-adjust feature, it’s easy to quickly tighten the booster to your vehicle’s seat, keeping it properly in place. The LATCH system establishes a secure connection between the booster and the vehicle seat.

Child Self-Buckle

Since the booster – both in high back booster seat mode and in backless mode – stays securely in place and properly installed to your vehicle’s back seat, it’s easy for your child to self-buckle. After all, “big kids” like to do things on their own!

Great Safety Features

The AFFIX Highback Booster Car Seat with Latch System is designed to help keep your precious growing child safe. This seat has been engineered and crash tested to meet or exceed standards, including:

  • U.S. Compliance Standard FMVSS 213
  • Side Impact Tested for Occupant Retention by the vehicle harness system
  • New Car Assessment Program (NCAP) – peak Crash Force approximately 2x Car Seat Standard
  • Extreme Car Interior Temperatures to ensure material integrity under extreme temperature conditions
Comfortable Ride

Kids of all ages are happiest when they’re comfortable, so as a parent you’ll love the comfort features built right into the AFFIX. The headrest was designed with multiple layers to maximize your child’s comfort. And, the full coverage back support provides comfort even as your child grows.

Adjustable Highback Booster Car Seat

Part of the safety of this seat is the headrest and the protection it offers to your child. So, it’s designed to be fully adjustable, so that you can always achieve the proper fit, keeping your child secure on all of your journeys together.

Kid-Approved Storage

Integrated cup holders are just right for holding your child’s cup, water bottle or snacks, and the hideaway storage compartment is perfect for storing for small games and toys. Bigger kids really appreciate these thoughtful extras that are just for them.

Bold Fashion

Big kids want a stylish seat, so older boys and girls will love the Atomic fashion. Bold red and solid black are accented with clean, white piping, for a look that’s perfectly age-appropriate.
