Matese.
Thanks for the tip on the tightness.
I think I see what my problem was. I put my seat in the center of my back seat ( middle of three) and I could not use the belt around the seat as my 3 seats are continuous. Looks like you need a bucket like seat that you can get around the back? Or a front seat? So my dog seat was just hanging from the headrest with no lateral constraint. So happy it works so well for your baby
