WANTED: Durable Chairs

We have a meeting area that is used daily by our division and occasionally the seating has to be cleared out for dances and other events. I'm looking for a suggestion for durable, "stackable" chairs. Our plan is to have tablets on about 25% of them with those having a fold-a-way option. If you have purchased this type of chairs in the last 5 years and have seen them hold up with heavy use, please let me know.
