If you encounter iron swing chair  and the door in a straight line, it is best to move the sofa away, so as not to collide with the door. If there is no place to move, then you have to put a screen between the two. In this way, the air flowing into the house from the door will not go straight to the sofa. If the sofa to the door is not a big problem, do not have to dodge left and right, there is no need to put the screen.
