Review on CasterMaster 3X3 Square Rubber Furniture Caster Cups with Non-Slip Floor Grip (Pack of 4) by Joshua Wheeler

I have 9 furniture legs (4 on the love seat and 5 on the full size sofa) but I only bought 4 to see if they really work. I've tried many different sticky pads but they end up wrinkling and breaking or leaving streaks on the floor. So far they're working great! I have laminated wood floors and I put 2 on the back legs of the full size sofa and 2 on the back legs of the 2 seater sofa. Both pieces of furniture are missing the front legs. Previously, only 2 at a time prevented the furniture from sliding across the room, even when wild children and a large dog jumped on it. Can't comment on durability yet as I've only had it for a few days. I'm still considering buying more for other legs, to be honest I don't need them yet. They do what they have to do! Finally a solution for sliding sofas! I would like to point out that they smelled very strongly of rubber. When I opened the bag they came in the smell was terrible. I left them outside to air out for a few days, washed them with soap and water, and then put them back outside for another day. They still smell when they reach my nose and leave an odor on my fingers, but I don't smell them at all in my room where they are used. It's quite a big room, but even with the windows closed and you're sitting on the furniture, no one smells it. My dog, on the other hand, apparently still smells it because I catch him on it.
