The Vevor grounding sheet is a queen-size fitted bed sheet designed to connect to ground through the included cord for a more comfortable sleep environment. It is made from 90% cotton and 10% silver fiber for a soft, breathable, and conductive surface suitable for year-round use. The fitted design accommodates mattresses up to 15 inches deep, and built-in resistance adds an extra layer of safety during use. Ground and socket testers are included to help verify proper setup and grounding.
