As a birthday treat recently I got to fly an A330 simulator, the seat on that was like an expensive car seat. It was motorised and slid back and to the side, allowing you to get in by stepping over the front part of the centre console, sitting down then gliding the seat back into position.
An incredible experience by the way, even though the views were obviously artificial it felt absolutely like the real thing. (A good job I suppose as our lives depend on them for pilot training
)
