The corner guardmust have zero imperfections of any kind on its surface. That means there shouldn't be any unusual bulge or roughness inside out. Also, like most safety equipment it should be easy to clean.

Hard-edge protectors won't conform to the corner they're supposed to protect, and for this reason, most manufacturers go with the flexible material route. When installed at the bottom legs of furniture the protector should not slide or skid.

Properties such as adsorption rate, anti-shock, anti-mildew, and thermal conductivity are all useful features in a corner protector. All these things ensure the material won't be hot to the touch and cause health concerns in your home.

Babies have a habit of putting all the things they see and touch in their mouths, and this may include corner guards. As such, you'll want one that has zero toxic substances and doesn't come with a strange chemical smell when you take them out of the packaging.

Last but not the least, you will want the corner protector to have a good quality adhesive that can stick to the furniture for a long time. If there are any overflows or traces, the adhesive should be easy to remove.
