Review on Non-Slip Carpet Stair Treads For Wooden Steps, 15Pcs 8X30In Slip Resistance Indoor Peel & Stick Stair Treads Carpet Runner Mats For Elders, Kids, Dogs, Staircase Step Rugs Stair Grip Non-Slip, Scarlet by Matt Abba

I installed these on a hard wood staircase to assist an aging dog who was slipping. My husband kept asking me if they were going to ruin the stairs. I assured him, they were not. We had them on approximately 9 months and while they were starting to peel (the carpet from the backing), they served their purpose very well. I took them off today and their was no residue - you cannot tell they were even there. I would give them a 5 star rating, except for the fact that they were starting to wear and would have needed to be replaced. But at less than $50 - well worth it.
