It varies. That said, I cannot comment on the middle row bench as I've never lifted one (all three of our Gen 3 vans had Captain's chairs in the middle row), however, the rear bench did vary quite a bit in weight. The bench in our 1998 DGC Sport was reasonably heavy at maybe 40 pounds, the bench in our 1998 T&C LXi was a bit heavier but not hugely so, and the bench in our 1999 T&C Limited was the heaviest of the group, I'm guessing over 50 pounds and possibly as much as 60 pounds.
