Ottomans are easy to add to your living room. They work well with armchairs, and you can simply place a small pouf ottoman in front of this type of seating. Add side tables to finish off this classic living room look. Ottomans can also be a great substitute for a coffee table in smaller spaces. Place a large storage ottoman in the center of your seating area and use trays to create hard surfaces for glasses, mugs, and plates.
