Custom Made Stair Treads Carpets Washable Soft Pile Solid Variety Color Option Stair Treads Size 7"x24" / 8"x30" (Set of 13)

These stair rugs do the trick. They are synthetic, not wool as it states in the description (though I was expecting this would be the case for the price). They are soft, fit the stairs well and look nice. They do slide around a bit. Not sure they'd stay put if I ran down the stairs.
