Review on 🪟 Set of 20 Round Furniture Pads by ULIFESTAR - Non Slip Leg Grippers for Wood Floors, Glides, Sliders and Caps - Carpet Saver, Surface Protection for Chair, Table, Desk, Dresser, Cabinet, Sofa Feet by Shane Hartford

Love it. They're only about 1/2 inch, similar to hard rubber, and seem to support the weight of everyday dining chairs. I bought them to add height and protect the lovely new chairs from the mop. (The picture shows two packages.) They don't slide the chairs in and out of the tile floor as easily as the hard plastic inserts that came with the chairs, but the downside to this is that the chairs don't slide out of the way, underneath you ( or my elderly parents) when you get up and sit down. they are not visible when the chair is on the floor.
