Hardwood floors are beautiful. I have them throughout most of my house. The only trouble is that once they're a few years old, the dirt and debris on the floor help to break down the varnish and they begin to scratch from moving furniture.
I've used these stick-on pads on my chair legs, but many times they don't stay in place.
I've found these floor protectors that are slightly different. There is still a pad with an adhesive, but it sticks to a plastic piece that is nailed into the bottom of the chair leg. My hope is that it will stay in place better than it does when stuck to the wood itself.
I know that I'll never have my floors so completely clean that there will be no debris under my chairs to scratch up the wood. But I do have high hopes for these new floor protectors. Maybe I can keep the scratching to a minimum.
