LOUFIMIDON Rubber Screw in Chair... vs 4 Rolls 1/2 x 60 Inch Self-Stick...

Hard rubber provides a little grip on a tile surface.

They fit on other furniture and thin lines of an ikea shoe rack. The width is on the lower side but no complaints. I have 2 kids and they tend to drag the rockers around and the felt just lets it slide without any damage.
