Sofa table

I've never had a sofa table before, or considered one. It looks like we're going to need one though. Remember the awkward space behind the couch? Yea, it's awkward. Plus, the living room is dark, we need a table lamp behind the couch. I'm not sure if I should go with a heavier, shelved table or an open table. A part of me would really like to see a distressed or rustic table back there but I'm not sure it would go with the rest of the decor?

Obviously ignore the picture mess but see how odd the space is?
