Rubber pads keep furniture from sliding underneath your couch. They also prevent your couch from scratching the hardwood floor. They are thick enough to withstand heavy furniture and not scratch orscratch the floor.
It is made of sturdy cardboard that is designed for storage and multiple uses.
After pre-drilling, there was no problem. X-protection furniture pads are just the right sized for my project. Chairs slide better and back to quite sliding.
