softtouch 2 1/2" Square Carpet-Bottom Caster Cups, Brown (12 Pack)

I bought my sofa from Walmart and I bought the coasters for the sofa because the legs come down and form a triangle and there's a little dip in the coast is perfect for what I needed it for I suggest getting these even if you don't have a triangular leg square round they're really really awesome 😁

I didn't know what I was getting at first. I have a chair that I use at my desk, and the ends of the legs were cutting into the carpet. There were other floor protectors that I'd bought but none of them worked. Then I saw these. I turned them upside down so that the carpet side was up, and Gorilla-glued each on to the bottom of the chair legs. I did this weeks ago now, and the chair slides across my floor's carpeting without any more damage or any sign that they're coming loose. I know it's not what they were intended for (and I did try carpet-to-carpet first with Elmer's to glue them on. They would hesitate and not slide at all.) But when I flipped them over, they did slide, and that's when I made the attachment permanent.
