At least the adhesive backing is worthless on smooth surfaces.
The adhesion seems to be tough so they stick fantastically well and i have no doubts it would last. Used these for all our chairs, couches, etc. Had a sliding couch problem on a wooden floor. They’re very easy to install on chair legs.
These pads are excellent. These are perfect non skid furniture pads.
Do not be fooled, these are not non-skid. There is nothing rubber about these, they are foam. Works way better. Stain my hardwood floor.
