They absolutely do the job. They make chair movements quieter. Seem to conform to different style leg ends and stay on securely.

The fu store clear self adhesive bumpers work exactly as expected. They are easy to peel off, they stick well and are thick. The grandkids come over and have to slam the doors on everything.

These things are garbage and keep sliding snd falling off. Too small and adhesive not very strong. If you stack 3 on top of each other they might be a bumper worth using.
