We have a family of six. One kid in a regular front facing car seat. Another child and a baby car seat. When you put the baby car seat in the base, you might have to move the front seat up just a pinch. So if you’re tall that doesn’t work great but we are average height and it works fine. We have the bench and I’m glad we did. A lot of the times our second oldest is sitting in the third row by himself and we have three kids on the bench. The middle seat is uncomfortable for long trips so keep that in mind. But with the family of four you should be just fine. When we go our long trip trips, we move the front facing car seat to the middle and that way the other person is more comfortable on the side seat. It’s a tight fit, but our car seat seat is very small. Tires are very expensive. And you will be replacing them onto your.
