Details

INTRODUCING THE SAFETY 1ST ONBOARD SLIDE DLX INFANT CAR SEAT FEATURING SAFETYSLIDE BASE The innovative design of the car seat’s base eases back strain and eliminates head bumps, making it easy to get baby in and out of the car––simply slide, lift, and go!
SLIDE, LIFT, AND GO SafetySlide stretches out a maximum of just under 8" on either side of the car, even from the middle seat. Distance varies depending on the width of the vehicle’s back seat.
SAFETY 1ST SECURETECH RED-TO-GREEN INDICATORS Our innovative design on the infant car seat’s base allows you to see when your base is locked in place when using the SafetySlide feature.
QUICK, EASY CAR SEAT INSTALLATION EVERY TIME without having to tighten the connectors manually—you can easily attach the base to the vehicle seat in just seconds with the rigid LATCH connectors.
INSTALLATION SIMPLIFIED WITH SECURETECH Safety 1st’s innovative technology solves the most common installation problem 7 out of 10 parents unknowingly have: loose vehicle belt tension. Red-to-green visual indicators show when the seat belt has tension.
ULTRA-LIGHTWEIGHT INFANT CAR SEAT DESIGN Weighing just under 8 lbs., you can easy lift and carry the Safety 1st onBoard Slide Infant Car Seat featuring SafetySlide Base in and out of the car.
DESIGNED FOR A BETTER FIT The 4 harness heights are designed to give your child a better fit from 4–30 lbs. (and less than 32"). The harness adjusts easily from the front of the seat with a simple pull to securely fit your child.
EXCEPTIONAL DESIGN MEETS EVERY STANDARD Rigorously crash and side-impact tested to meet safety standards. Meets federal Side Impact standard.
A COMFY BABY IS A HAPPY BABY Your baby will be nice and comfortable relaxing in the soft fabrics and plush padding. Smaller babies get the extra support they need with head and body inserts that can be removed as they grow.
MAKE IT A TRAVEL SYSTEM Compatible with all Safety 1st modular and traditional strollers to easily become part of a travel system with QuickClick, for a secure one-click attachment.
