The main challenge in a living room is accommodating the room’s space, shape, and light. Living rooms aren’t always nice rectangles suitable for a theater orientation, and they often open up to dining rooms, foyers, and kitchens. They may be L-shaped or have stairs, doors, and windows in all the wrong places. Seating may include a sofa and mismatched chairs scattered around the room. They’re also not caves, so light from windows, lamps, or nearby rooms is likely to be leaking (or pouring) in.
