I have nice leather livingroom furniture. My issue is with the two big chairs. They have casters on the bottom. On our hardwood, they are constantly rolling. Not only do they scratch the floor, but with 3 teens in our house, they get rolled into the wall paint a lot. I've had them for years and have attempted different sliders under the wheels to stop the rolling, but nothing stays put. I e tried to figure out how to get them off, but see no way of removal. Has anyone seen this or experienced this that may have some good suggestions? Ty!
