I've purchased these stair treads before. We have a split level house, so our stairs are constantly being used! I purchased the solid gray color so that they blend in with my dark wood flooring. I don't want them to be a focal point; I just want them to save my stairs and stop me from slipping! I wash them on gentle cycle approximately once or twice a month; shake them out in-between washings. They last about 8 months before the backing starts to wear off and they don't hold in place as well. I'm realistic. They aren't made to last forever! I'm satisfied and will continue to purchase them when the time comes.
