• How does the Quantum Grounding Sheet work?

  The Quantum Grounding Sheet is woven with conductive silver fibers that allow you to connect to the Earth's natural energy when plugged into a grounded outlet. The included grounding cord links the sheet to the ground port of an electrical socket, creating a connection similar to walking barefoot on grass or sand.

• Do I need to plug the sheet in for it to work?

  Yes, to experience the benefits of grounding, the sheet must be connected to a grounded outlet using the included grounding cord. It does not require electricity, as it only connects to the ground port, not the live electrical current.

• What size mattress does this sheet fit?

  This is a queen-size fitted sheet measuring 150cm x 203cm (58” x 78”) with a 12-inch deep pocket, making it suitable for standard and thicker queen-sized mattresses.

• Can I use a mattress protector with this sheet?

  For the best grounding connection, it’s recommended to sleep directly on the sheet or use a thin cotton cover. A thick mattress protector or synthetic materials may block conductivity.

• Is it safe to use every night?

  Yes! The Quantum Grounding Sheet is completely safe for nightly use. It does not emit any electricity; it simply allows your body to connect to the Earth's grounding energy while you sleep.

• How do I clean the grounding sheet?

  To maintain its effectiveness: 1. Machine wash in cold water on a gentle cycle. 2. Air dry only (avoid tumble drying). 3. Do not use bleach, fabric softeners, or harsh detergents. 4. Do not iron or dry clean.

• How long does the grounding effect last?

  With proper care, the conductive silver fibers in the sheet can remain effective for several years. Regular washing with mild detergent and air drying will help maintain conductivity.

• How do I know if my outlet is grounded?

  If you’re unsure whether your outlet is grounded, you can use a grounding tester, available at most hardware stores. Alternatively, plugging into a grounded power strip with a grounding port should also work.

• What if my outlet isn’t grounded?

  If your home does not have grounded outlets, you may need to use a grounding rod placed outside in the soil to connect your sheet properly.
