Furniture placement principles
There are a few general guidelines:

Even in a small living room, each thing - it could be a combination of different items of upholstered furniture - should be organized as comfortably as possible; seats should preferably be placed based on of those present conversations, i.e. facing each other or at an angle of 90 degrees; if a living room can accommodate two sofas - it is better to put them at an angle, and chairs placed side by side, creating the illusion of space limitations.

 In this case, a carpet will come in handy to designate the borders of the seating area and its area - closed sitting area; to visually expand the boundaries of the living room, pull the bed away from the wall, leaving a passage of at least 60 cm. If the space allows, a desk or bookcase can be placed behind a small couch, whose length may be restricted by the size of the sofa or surpass it.
The center of the living room composition may and should be designated, for example, by a coffee table between the seats. If the furniture is facing the wall, the composition's focal point might be any item on it, such as a screen, fireplace, or window.
