Corner protectors are commonly made from silicone, PVC (polyvinyl chloride), foam, plastic, and rubber.
Product descriptions state they adhere best to smooth surfaces and commonly list compatibility with wood, metal, glass, and plastic furniture.
Both types are available: corner-only guards that cushion the corner point, and extended edge protection (cut-to-fit foam or wraparound edge cushions) that protect along table edges as well.
Many product descriptions and reviews report that corner protectors are easy to install and remove, often using non-damaging peel-and-stick adhesives that can be peeled off without leaving residue on smooth surfaces. Removability and residue risk can vary by adhesive type and the furniture’s finish.
Product descriptions and reviews commonly describe installation as quick and easy—typically peel-and-stick or one-person install—and note that the guards are straightforward to apply and remove.
