There are several reasons one might add a runner to a staircase. One of the most common is safety. Wood or tiled are often quite slippery, which can present a hazard, especially when there are children, pets, or people with mobility issues in the home. Adding a runner reduces the danger by providing a safer, more comfortable surface underfoot.
Carpet also absorbs much more noise than hard surfaces do, which will make trips up and down the stairs much quieter.
Let’s not forget style! A carpet runner has the ability to transform a staircase into a beautiful focal point in your home. There are two options when choosing a runner on stairs: a pre-made runner (usually featuring a pattern), or a custom-made runner, often made out of broadloom.
