Give your baby a secure and comfortable ride in the Safety 1st onBoard™ Slide DLX Infant Car Seat featuring SafetySlide™ Base. The innovative design of the car seat’s base makes it easier to get baby in and out of the car—simply slide your baby toward you, lift, and go. No more back strain and head bumps. The SecureTech™ red-to-green indicators on the seat’s base allow you to see when your base is locked in place when using the SafetySlide™ feature.

Enjoy quick, easy 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.

When using the vehicle belt, installation is simplified with SecureTech™—Safety 1st’s innovative technology that solves the most common installation problem 7 out of 10 parents unknowingly have: loose vehicle belt tension. The red-to-green visual indicators show when the seat belt has tension.

The ultra-lightweight design at just under 8 lbs. makes it simple to carry, too. 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. The buckle adjusts in two ways so that you can customize the length and the buckle’s position on your child. Since every car is different, you can also adjust the base height for the right fit to your car. 

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. Additionally, the extra-large canopy with zipper extension offers more sun coverage and makes it easy to check in on your little one without adjusting the canopy.
