Hi Alicia,

We had ours S&S Meridian professionally installed (in the rear facing position) by one of the RTA approved fitters. He solved the wobbliness by padding with a small folded towel. He put it between the safety bar (the one that's at the feet end of the S&S seat) and the back of the passenger seat . Does that make sense? I can take a picture of it for you if it doesn't make sense?

Hi there we had the S&S Compaq installed and same they solved the wobbliness by a small folded towl between the saftey bar and the back of the back seat (as our carseat is reversable). This was done by RTA approved installer.
