Sofa tables are pretty popular right now. They are skinny and long and fit so nicely behind a sofa and can help further decorate a large space. You can use them to better divide a space where the sofa is in the middle of the floor but they also work well behind a sofa up against a wall. We needed something between the wall and sofa.
As we started working out what we were going to do I had an epiphany realizing a simple wall shelf would give the appearance of a sofa table by placing it lower on the wall. It would also be cheaper to DIY since there is less wood needed for a simple shelf versus a sofa table with legs.
