Our double daybed it seemed to go of its own accord every time we sat down and leaned back on our smooth floors. Well, we finally realized that the six tiny feet (about 1 inch in diameter) on the polished stone floors needed some help. We added 2 inch cushions to the legs of the sofa. and noticed instant results. First we wiped down the bottom and legs thoroughly with alcohol to ensure a good grip. No movement even with typical force to move furniture. And despite frequent use, even double use, the sofa stayed in place for weeks. I really didn't expect these cushions to work so well, but they do! I also used 3 inch pads on another chair and they worked well too. Measure around your feet to decide which size to purchase. But 2″ is incredible holding power despite its size.
