I wonder who has looked at the history of pews. I know that in old churches in New England, they have little \"box seating,\" with fairly tall separators. I heard that a main reason for the sections was heating; each section could have a little heater.
Standing and sitting in the old world are very different. Back in the day, standing was a way of showing respect, now reserved in the US for the President, judges, and the military. But back in the day, students stood while the teacher sat. Of if the student sat, it would be on the floor at the \"feet\" of the teacher. In Kiev in the early 90s students would all stand when the teacher came in the room.
I also heard that sitting to work is relatively new. I heard offices only started having sitting desks in the early 1800s. Before that you would stand or lean, kind of like chanters\' stands. In old centers of Jewish learning you can find two podia facing each other for colleagues to stand at when they argue with one another.
Standing is a symbol, and symbols\' meanings change over time and in different cultures. I get the feeling that nowadays standing during the whole church service makes as much sense to most people as standing to type at work. In our world, one shows respect by listening and being nice, rather than the outward sign of standing and sitting.
But as I said in the beginning, pews are murder for kids in church so I prefer to avoid them.
