I hate the empty space that is behind my couch and want a table there to add flowers to the living room. I have heard about people using a sofa table but am not very familiar with them. Is this something people do to add decor to the living room?
I would say that adding a table behind your sofa is a pretty common practice. A lot of people do it to add flowers or other decor to your home. Just make sure you find one that matches your exciting tables and furniture or it will look out of place. Yea a sofa table is a good idea to create what you are looking for.
Yes, a sofa table is a great way to liven up a room, though as others have said, it's best to add one in the same style as the rest of your furniture. A classic sofa table is quite tall, though lower than the back of your sofa, quite long, but shorter than your sofa, and not very wide. Sofa tables look great with lamps on, if there's nowhere you can plug these in, use a pair of candlesticks or some matching ornament, and put flowers in a low vase in the middle. Many people find a desk is just the right height and length to use as a sofa table, and if you want one in your living room, behind the sofa can be a very good place to put one. An alternative is a low bookcase. You get storage on the shelves for ornaments and/or books, and a surface to display your flowers, lamps and other ornaments.
