Earthing Fitted Sheet — US Sizes, Twin to California King

A fitted earthing (grounding) sheet in 90% cotton and 10% silver fiber, in US bed sizes from Twin to California King. A cord connects the conductive sheet to the ground port of a wall outlet, which ties the sheet to your home's electrical ground. This is a grounding product, not EMF shielding: it doesn't block or reduce wireless signals.

How to Check It Works

First, plug an outlet tester (sold at hardware stores) into the outlet you plan to use: it shows whether the ground is actually wired. Then, with the cord unplugged, set a multimeter to continuity and touch one probe to the sheet and the other to the ground prong at the plug end. A beep means the sheet, cord and plug are connected.

Honest Notes

• It only connects to ground if the outlet's ground is wired. Two-prong outlets have no ground port.
• Silver fiber loses conductivity with harsh washing. Wash gently and skip bleach and fabric softener.
• It isn't a medical device. The glossary link below explains what grounding does and doesn't do.
