If the sofa is in a straight line with the door, it is called "hedging" in Feng Shui, which has great disadvantages. In this case, it is best to move the sofa to avoid collision with the door. If there is nowhere to move, then you have to place a screen between the two, so that the air flowing into the house from the door will not go straight to the sofa. If the sofa faces the door, there will be no serious problem, and there is no need to place a screen to resolve it.
