You're wise to keep the couch free of all clutter with exception to a few pillows. Let the design of the room reflect your personal image and let the furniture be available to function.
The empty couch says "sit".
Without having to move items to sit, the ability to act immediately on your idea to sit, means you are halfway to finding peace in relaxing.
Find peace and open your mind and heart to clarity...what wonderful peace you have. You are wonderful and you deserve great things!
