Our Classic Keshan treads came a few days ago. They are well made, look terrific and really do stay in place on our hardwood stairs.
We cleaned the stairs first with Bona just to be sure there was nothing to interfere with the treads.
We then placed the treads on the stairs. No tacks, no tape -- nothing but the treads. They have not moved, they function extremely well and really look good doing it.
We are very pleased. I plan to follow this up in 6 months or so, just to give the treads a longer term review.... but I will be very surprised if they are not still fantastic.
Great Product. We love them.
