You should not try to restrict the person's movements. You have to follow them. If the seizure happens in a room, good. But if the seizure happens outside, it is different. We have seen a young woman get up and walk quickly outside. It's rare, but it happens. Someone must be at the person's side to make sure that they don't hurt themselves by falling down a staircase or anything like that. Seizures are very short. You should not try to restrain the person or sit them down. You must follow them, make sure they are safe and talk to them, because that is how you can tell when the person is no longer unconscious.
