ABSTRACT:
A reusable stair cover is described having a length of washable material for covering a number of stair treads and intervening risers. At least one tread-covering portion of the cover includes a non-slip finish for contacting with the stair tread. Alternatively, each tread-covering portion further includes means for accepting a rigid insert. In another alternative embodiment, the length of the tread-covering portion is approximately a minimum tread length, and the portions between the tread-covering portions is long enough so that the stair cover can cover a range of staircase geometries.
