According to my Britax manual, the base of my DD seat shouldn’t be anything but level on the seat. The problem is that the dip in the backseat prevents that. As I’ve said b/4, we have it installed currently RF at a 45-degree angle, but the base is not level due to the car seat wedge used to install it by the tech. This wedge is too big to make the seat base be level with the next RF install at less than 45-degrees, so should I use a rolled up towel or swim noodle? I know the best place for the seat is in the center, but then having a passenger in the back is extremely difficult. Thanks in advance for your input!
