Portable/Folding Benches for location group shots?

Anyone have suggestions as to a good portable (ideally folding) bench that would be suitable for bringing on location for team group shots?

I've been running google searches using every phrase I can think of and haven't really come up with anything useful (most hits I'm getting seem to be those folding-canvas-camping-chairs-chained-together-to-make-a-bench ... not really usable for posing a team for photos).

Thanks.
