Living room 4 meters wide, 4.2 meters long, how to choose the sofa?
The length of the sofa can not exceed 3.5 meters, width is generally nothing, 4.2 meters width is usually ok,
2.5 of the sofa, and then put a small cabinet at the door, so as to avoid others see the sofa as soon as they enter the door. Of course not. You turn, huh?
