Tranzitions® SnugLock® 3-in-1 Harness Booster features SnugLock technology for an easy installation in less than one minute using vehicle seat belt or LATCH.

This lightweight booster car seat transitions seamlessly from harness booster (10-30 kg) to high-back booster (18.1-45 kg) to backless booster (18.1-45 kg* must be over 30kg and at least 109 cm – 144.7 cm in height, *we recommend to use once full back booster has been fully outgrown) and features the no-rethread Simply Safe Adjust™ Harness System, which adjusts your harness and headrest to 9 height positions to easily adapt for your growing child.

The seat pad, body support, and harness covers are comfortable and machine-washable, making clean-up a breeze. Fuss-free harness storage makes it easy for your child to get in and out. This harness booster is also LATCH-equipped for hassle-free installation. The seat is Graco® ProtectPlus Engineered™ to help protect in frontal, side, rear, and roll-over crashes.
