Chairs and Recliners

What kind of plastic are office chairs made of?

I need to do product research on the cost of plastics for chairs and I can't find anything online that will tell me the type of materials. Can anyone tell me what kind of plasic some chairs are made of? For example a computer chair because of their durablility.
