What do you ladies use for protecting furniture corners?

Im in canada so amazon US may not be able but still want to know!

I have wooden tables and want to put something on the corners so my son doesnt get hurt. Kinda sucks that with most protectors you can only cover the top part of the corner not the bottom.. i guess thats normal?

What do you ladies use that also doesnt damage your furniture and actually sticks on?

Been looking for a black protector but they are all foam and I know my son will eat it lol. And the clear ones dont look so nice… still open to see what you ladies use!
