A stair riser is the vertical component between each step. It connects the treads (the horizontal part of steps where one places their foot), and is thus the face of the step.

Risers ensure the height between each step is consistent, reducing the risk of trips and falls. Also, they protect the structural integrity of a staircase. In small homes, where every inch of space matters, you can use these five innovative ideas to decorate stair risers.
