EMF Shielding Bed Sheet - Metal Fiber Mattress Cover

A metal-fiber shielding sheet that covers the top of a mattress — woven from stainless steel fiber blended with cotton, in silver gray, in two European sizes. It's conductive fabric, so it reduces RF passing through the area it covers: here, signals coming up through the mattress. It's a shielding product, not an earthing (grounding) sheet.

Details

• Material: 316L stainless steel fiber blended with cotton (the manufacturer lists 50% cotton)
• Color: silver gray
• Care: listed as machine washable

Sizing

• 150 × 200 cm (about 59 × 79 in)
• 180 × 200 cm (about 71 × 79 in)

These are European mattress sizes and don't match US beds exactly (a US Queen is 60 × 80 in, a King 76 × 80 in), so measure your mattress before ordering.

How to Check It Works

Use an RF meter. Lay it flat on the bare mattress and note the reading, then put the sheet down, set the meter back in the same spot and position, and compare. The sheet only sits under the meter, so signals arriving from above or from the sides still reach it. Expect a change, not a reading of zero.

Honest Notes

• It covers one surface. It isn't a canopy or enclosure and does nothing for signals from above or around the bed.
• It's sold as a shielding sheet and no grounding cord is listed. For the difference between grounding and shielding, see the glossary.
• The manufacturer's shielding-percentage and frequency claims are left out: we have no independent test report for this sheet.
• It isn't a medical device.
