Why stairs wear faster than any other floor
- Every footfall compresses the pile against the nosing edge of the tread, concentrating wear on a narrow strip
- Poor gripper fixing on stairs is more consequential than on flat floors, because carpet under tension on a step takes more mechanical load
- Worn nosings underneath accelerate carpet wear, a rounded or splintered nosing edge cuts into the carpet backing from below
- Winders and bullnose steps see extra stress at the pinch points where the carpet is folded tightest
- Poor quality underlay or none at all on stairs increases impact wear significantly
