If you are looking for a way to keep your child safe and comfortable while they are in their car seat, Baby Jogger car seats are a great option. Not only do they provide excellent safety, but they also come in a variety of different styles and colors to fit any taste or style of child. To install a Baby Jogger car seat base, first remove the old base from the carseat. Next, cut the new base to fit the specific size of the carseat and attach it to the old base using screws. Once it is attached, tighten everything down using screws until it is secure.
