The base is LATCH equipped and has two position recline to help with an easier installation.This extra base is compatible with the Safety 1st onBoard™35 LT, an infant car seat that provides your baby with a superior fit. The seat (not included) is also designed to be easier for parents to use. It’s a light infant car seat that can accommodate a baby up to 35 pounds, making it much easier to carry. The harness adjusts easily from the front of the seat with a simple pull for a secure fit for your child, and the base height adjusts for the right fit to your car.

Review: So cute, sturdy and soft. Not bulky! - This car seat is very nice, sturdy and the seating is so soft. Not bulky or heavy like other car seats I’ve gotten. Excited to bring my baby boy home in this. Definitely recommend!
Review: Quick and easy! - I’ve bought this car seat base three times now because it makes life so much easier with little ones. We have one in each of our cars so we don’t have to worry about moving just one back and forth. Installation is quick and secure, and I always feel confident that my baby is safe. The seat clicks in and out smoothly, which is a huge help when juggling kids and diaper bags. With two kids (a toddler and a newborn), the convenience of having multiple bases has been a total lifesaver for our busy family. Highly recommend to any parent who wants both safety and simplicity!
