It's best to put the sofa against the wall, not facing the passage or leaning back. From the perspective of geomantic omen, it is carefree to have a backer against the wall. If there are doors, windows and passages behind the sofa, and there is no wall to lean on, it will form a loose situation and people and money will be hard to prosper. The remedy is to put furniture such as screens and low cabinets behind the sofa to make artificial cushions. Things are a little better.
