I have both the small and the medium (I think-got in a consignment store). My 2 are 4.5 lbs about and fit in the small. I have the small in my suv. Chances are is that I only go short distances with both.
We use he larger one in hobby's suv as we drive further distances so hey can both lay down comfortably. I have a Toyota 4-runner and the larger seat takes up every bit of he front passenger seat. The air bag is not activated by the carpet.
Good luck. I totally recommend the snoozer carpet. |
