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.

Best friend with hardwood flooring. Easy to put on. Chairs glide like silk with no friction.

Half on hardwood, half on rug. Getting the sticky glue off the floors are a nightmare! Would need super glue to make this work.
