Thses make our hard basement/garage steps feel SOOOO much better. We got the gray...which hides EVERYTHING. I like the fact that they can be moved and washed, if needed. If you are looking for it to stay put....then you need to purchase tape. With the ease of washing them we did not purchase the tape....sometimes I have to put them in place as they do move with kids going up and down...not unsafe...put my OCD kicks in when it's not lined up. I recommend these product for the quality and price.
