I have now decided that stair carpet is the enemy. It attracts so much dirt. It is a horrible colour, sheds fluff and looks tatty even when cleaned thoroughly.
I would like to remove it entirely, but concerned about two things.
Noise - carpet does make things quieter. If I use wood instead, it could be loud?
Safety - basically it must be easier to slip on wood stairs?
I would be really interested to know how do other posters find having uncarpeted stairs? What did you use instead?
My intention would probably be to clad the steps; the remainder of the staircase is sound.
