Ah, my living room:
Standing on the West side, there is a recliner right in front of me, facing east, with a glass end table on the north of the chair. Across from the room is a love seat with a combination footrest thing/container, filled with board games. On the south side of the room is a couch with a metal and glass coffee table in front of it and across from the couch is the television set. To the east of the TV are improvised shelves (from boards and cinderblocks) filled with DVDs and video tapes. To the west is my mother's bedroom door. Further to the west is the computer desk with a cloth and wood folding "director's" chair. In the corner to the east of the couch is a corner china cabinet (my grandmother's). Hanging from the center of the ceiling is a lamp that lights the entire room fairly brightly. The couch, recliner, loveseat, and footrest thing are all a dark navyish but not quite navy blue.
Starting approximately with the recliner and going west is light brown carpet, and hardwood behind the recliner. Directly behind the recliner is the dining room table, although this is technically not a dining room. A bit south and west of the recliner is a second china cabinet with various fantasy-themed crystal decorations that light up. To the west of the computer is a "bar" bordering on the kitchen, with an unused aquarium sitting atop it. Right up against the bar, on the south side, is a small bookshelf filled with children's books.
Behind the loveseat are three windows with Venetian blinds. Sometimes the blinds are open, sometimes closed, and sometimes drawn entirely.
It's not hard to keep the details in mind because I see it every day. Still, I can visualize all that and more (I felt like some descriptions were getting overly verbose and cut them). I can also remember the layouts for every other living room in every other house I've lived in.
