Maybe 30 years ago a company called Ook from Germany changed how people hang pictures. Before Ook you used nails and they were almost free.

After Ook you used “professional picture hangers.” They were much better and much, much more expensive.

There is an opportunity to do the same thing with the little protective feet that go on the bottom of chairs and other furniture on fancy hardwood floors.

We have beautiful new hardwood floors in our kitchen and family room. They look great but scratch really easily.

I have been putting on the best available felt pads but they are not ideal. The felt is soft but not a very good cushion and the adhesive fails regularly.

The ideal pad would have an epoxy or other super glue like adhesive and a molded urethane shaped contact surface that was a variable ILD construction. ILD is a acronym for Indent Load Deflection. In a much larger format it is why beds have springs and pads. The pads design is not the critical thing however it is the marketing. People who spend ten thousand dollars on a beautiful floor will be more than willing to spend hundreds of dollars to protect it. And in fact they want to spend the money to protect their floors.
