The most important thing to know before adding visual interest to a space is scale and verticality. Scale is how the size of an object relates to the size of other objects around it or the size of the room. Verticality involves positioning objects to the right angle of the horizon.
Using scale and verticality allow you to make a room look more visually appealing by placing objects in different planes. You want your home to look layered, in other words; avoid putting everything at the same level. This also goes for furniture, not just decor.

Using pedestals is one of the simplest ways to add visual interest to a room. You can place a large vase on the floor with large scale greenery beside a pedestal that houses a sculpture.

Visual interest is just as important when it comes to styling a console table, credenza, or coffee table. Make sure not to add multiple objects of the same scale together, this can make it look cluttered, rather than layered.
