Should I hang a mirror or wall art above my sofa?
A mirror and a piece of wall art fill the space above a sofa differently, and the better choice is clearest when you preview each on that wall.
A mirror bounces light around the room, makes a wall feel deeper, reflects whatever is opposite, and stays visually quiet, which suits a darker or smaller space. Wall art adds color, mood, and a clear focal point, and it sets a tone the mirror cannot. One opens the wall up; the other gives it a voice.
Seeing each above your sofa shows how it reads against the wall color and how it relates to the sofa's width below. DecorViz lets you preview a mirror, then a piece of art, on the same room photo and compare. The previews show scale and how the piece sits over the sofa.
