Our 3 dogs started slipping down the last few stairs while racing to get to downstairs door to the outside. One got spooked and would always stop before the landing.  These treads are absolutely terrific!  Not only do they stay put, they are really beautiful and add much need to color to very dark wood stairs.  They were reasonably priced, arrived very quickly and I could not be more pleased.  And most importantly, the dogs looooove them and the two-legged people in the house feel more secure on them too
