We recently got some pre-finished new flooring w/ aluminum oxide incorporated into the finish.
For our more stationary furniture, the felt floor protectors work well.
Not so much with the dining room chairs - they have plastic "buttons" on the end of the legs. The felt floor protectors (circular) keep falling off - probably because the buttons are smaller than the diameter of the felt pads.
Do we really need the felt floor protectors on the chairs? If so - does anyone have a better solution for a way to attach them? The sticky backing isn't working that well on the buttons.
