Re: Which vans have seats that fold into the floor? Going back to the OP--we have a 2005 Nissan Quest, and the 2nd row captain's chairs fold down almost flat. They don't go into the floor, but the floor of the 3rd row is slightly raised, so the 2nd row seats collapse to create an almost flat floor. We've only used it that way a few times.
