Making seats sitable?

How do i make it so you can sit in chairs and benches in source SDK?

Make a prop_vehicle with a certain seat model and make it transparent via another entity?

Make them very comfortable.

That’s not what he meant. He wants to make a chair in hammer editor, not garrys mod.

This thread is from 2009 you know.

Also, iirc sittable chairs only existed in garrysmod, and there actually was a way to place them in hammer. I don’t remember how unfortunately. (through some entity or something)
