Your body needs to be in an alert or awake position in order for you to be able to settle into yourself. Sitting on a couch will just make you sleepy.
It's also hugely important not to expect anything out of your meditation. "Having trouble focusing" is only a symptom of what's actually going on. Meditation won't make it go away; but, if you stick with it, you'll likely gain insight into the causes of it, and hopefully find more productive ways of dealing with it.
