I use them as carpet hold down weights on out outdoor rv carpet. They look great and hold up to the elements outside. Our new home has a hardwood floor in the bedroom.

Adhesive to keep the position right, and velcro to hold to itself at the right fit. Since these are held on by velcro, they stay on. Even if they roll off the pad, they seem to still protect the tile.

I searched for something else and found these and figured i would give them a shot -and they are great! Highly recommend. Good product.

They slide if the chair moves, no matter how tight you wrap the velcro. They seem ok in quality but do not stay in place on the chairs i have which are similar to the ones depicted in the thumbnail image.
