A grounding sheet looks like ordinary bedding. The difference is inside the fabric and in the cord that comes with it.
1. A conductive fabric
Fine conductive threads are woven into the sheet, usually alongside cotton. They run across the surface, so wherever your skin touches the sheet, it touches a conductive path.
2. A snap and a cord
A metal snap on the sheet connects to the grounding cord. The cord carries the connection from the sheet to the wall.
3. The ground port
The cord plugs only into the ground port of a properly grounded outlet. That port doesn't carry electrical power. It's connected to the earth through your home's wiring, which is what links the sheet to the ground.
4. Your skin
The connection works through bare skin. Lie with your legs, back, or arms on the sheet. Pajamas between you and the sheet block it.
Half sheet or fitted sheet?
- A half sheet lies across your existing bedding. It's quick to add and easy to move.
- A fitted sheet covers the whole mattress, so you're connected wherever you move.
Before you start
- Test the outlet with an outlet tester.
- Wash the sheet as the care guide says. Skip fabric softener and bleach, which can coat the threads.
- Disconnect the cord during thunderstorms.
