The original covers attached to the legs of dining chairs tend to loosen over time with daily use. If you don't notice this and sit on or move the chair with the cover detached, there's a risk of scratching or denting flooring materials like hardwood or cushion flooring. This product is a compatible leg cover designed to prevent such problems. It can be used as a replacement for original covers that have deteriorated or become loose, and it protects the legs to reduce damage to the floor. By regularly replacing these as consumables, you can keep your chairs and floors in good condition for longer. We recommend replacing your chair leg covers with these compatible covers when you start to notice looseness or detachment as a measure to protect your chair legs. Also available in a great-value set of 4.
