I was looking at the screw in felt pads, and wondered if they would be a good solution for floor protection.

The ones I was looking at have a felt pad that the manufacturer attached to a metal piece then put a screw through both. You then take the piece and screw it to the bottom of the chair leg with the metal part against the wood and the felt to the floor. This might seem like a good idea, but my first thought is what happens when the felt either flattens or wears down. Then I have either the screw scratching the floor, the metal piece scratching the floor or both scratching the floor and you can bet that they’ll do more damage then just a bare wooden chair. I just wouldn’t want to take that big a chance with my floors.

With the Flexi-Felt Clear sleeves, when the felt wears down you just have the clear part rubbing the floor and that wouldn’t cause any damage. A much safer solution for protecting floors.
