Description

Give baby a comfortable, secure fit with the ultra-lightweight onBoard LT Infant Car Seat. Weighing less than 8 lbs., this seat is so easy to carry. The 4 harness heights are spaced just right to give your child a better fit from 4-30 lbs. The buckle adjusts two ways so that you can customize not only the length, but also the buckles position on your child. Smaller babies get the extra support they need with head and body inserts that can be removed as they grow. The seat is also designed with a reclined body position for a more secure ride. The harness adjusts easily from the front of the seat with one simple pull, and the base height adjusts for the right fit in your car. The car seat is compatible with all Safety 1st strollers that feature QuickClick, which allows you to attach the infant car seat to your stroller with one simple click, making it easy to use the car seat and a stroller together as a travel system.
