stair carpet runner
Stair runners are not only good for safety purposes, but make them quieter too. You can add a stair runner, or even fully carpet just the stairs in a home that has other flooring such as wood or tile. Use a very low, dense pile, and again, I'd go with something that has a little variegation and randomness in its pattern if you're not a vacuum daily type of person.
Tone on Tone: I chose a wool sisal style staircase runner with very narrow binding. It's installed about 3 inches from the sides (and cut out around the newel post) in the Hollywood style, which is tailored and bespoke. The big area rug is the same, but with a different binding. Larger area rugs do wonders for small spaces!
