That looks like a bench with a fold down backrest in the center. For cupholders and center armrest. My Avalon has that, with a small access door(8"x6") to the trunk. Maybe big enough for some ski's but not much more.That ain't no bench. Look at the seat bolsters in front of the seat belt.
Now, if by "bench" you mean a single piece seating installation, without splits, maybe. But this pic doesn't explain it one way or another.
