We purchased these anti slip furniture pads to use under the legs of the furniture. These are good at the job, Various size and sticky great. No more sliding from the furniture feet, Very pleased furniture pads.

I'm super happy with these. The front of my sofa is on a rug, the back is on hardwood floors. It's been sliding around a bit when you fall into it - these did the trick and are now holding the sofa securely in place.
