EMF Shielding Bedding That Fits Like Normal Bedding
Swiss Shield® EMF Blocking Faraday Bed Sheets put shielding fabric into your bed itself. Fitted mattress covers, duvet covers and pillow covers go on just like ordinary bedding, and the fabric reduces the RF signals from WiFi routers, cell towers, smart meters and other wireless devices around your sleeping area. There is nothing to assemble.

Quick, Discreet Fitting
- Fit the mattress cover, which has elastic corners, over your mattress and mattress protector.
- Put your duvet and pillows into the EMF duvet and pillow covers.
- Make up the bed with your usual sheets, duvet cover and pillowcases on top, so the shielding fabric sits beneath them.
From the outside your bed looks completely normal, with an extra layer of shielding fabric underneath. The lightweight design also makes it easy to take with you when you travel.
Keep It Beneath Your Normal Bedding
We recommend using the Swiss Shield® fabric beneath your normal bed sheets, duvet cover and pillowcases, not as your top layer. The fabric can be washed up to 40 times, so keeping it under your everyday bedding means you wash it less often, and it lasts longer.
More of Your Sleeping Area Covered
A mattress cover shields from below, while the duvet cover and pillow covers add shielding fabric around and above you. The fabric is lightweight, soft and breathable, so there are no heavy layers.
Swiss Shield® Fabric: Naturell or Ultima
The bedding is made from Swiss Shield® Naturell or Ultima, your choice. Both are breathable and have exactly the same composition: 82% cotton, 17% copper and 1% silver. The yarn is cotton fiber spun with a gossamer-thin silvered copper thread, just 0.02 mm (about 0.0008 inch) across, and a PES coating makes the fabric non-conductive. Ultima has a slightly tighter weave, which gives slightly more protection across the cell and WiFi bands.
Swiss Shield® fabrics are developed and manufactured in Switzerland as sustainable, durable textiles in the premium segment of the market. They are certified to OEKO-TEX® Standard 100, Product Class I (baby articles), meaning they are stringently tested for harmful substances, and their EMF shielding performance has been independently tested by EMF Test Lab Bavaria. The fabric is lightweight and translucent (semitransparent), in a natural ecru or off-white color.
Shielding Performance
Independent testing covers 600 MHz to 40 GHz on a single layer of fabric, the same as used in the bedding. Ultima provides up to 44 dB at 700 to 820 MHz (4G LTE), about 41 dB at 900 MHz, 38 dB at 1800 MHz, 36 dB at 2.45 GHz (2.4 GHz WiFi), 32 dB at 3.5 GHz (mid-band 5G) and 28 dB at 5.8 GHz (5 GHz WiFi). Naturell provides about 41 to 42 dB at 700 to 820 MHz, then about 37 dB, 35 dB, 34 dB, 28 dB and 27 dB at the same frequencies. At millimeter wave frequencies (20 to 40 GHz), the fabric provides modest shielding of about 11 to 17 dB. Decibels are a logarithmic scale: every 10 dB is a tenfold reduction in signal power, so 30 dB means 99.9% of the signal power at that frequency is blocked. See the Specifications tab for the full table.
These are laboratory figures for the fabric. Bedding is not a sealed enclosure, so the reduction you get in practice depends on how much of your sleeping area the fabric covers, and on the room and where your devices are.
No Grounding Needed
Swiss Shield® fabric is PES-coated and non-conductive, so the bedding works without grounding. You do not need to connect it to mains electricity or to a grounded wall or floor.
Care and Washing
The bedding can be washed up to 40 times while keeping its shielding. Swiss Shield® is made from a very thin silvered copper thread under a protective PES coating, so please follow these instructions:
- Wash on a wool cycle or hand wash cycle only.
- Use only mild biological or ecological detergents. Do not use aggressive detergents.
- Never bleach the fabric.
- Do not tumble dry. The fabric must be line dried (hang dried).
- Use front-loading washing machines only.
- Protect the fabric from undue mechanical stress.
The thread and its silver layer are both very thin, so mechanical or chemical stress can damage the PES coating, or even the silver layer itself. The fabric may then discolor and, over time, lose some shielding. To get the most from your bedding, keep it beneath your normal bed sheets as we recommend, and wash it only when needed.

Not completely. The sheets use shielding fabric that significantly reduces certain RF frequencies, but bedding is not a perfectly sealed Faraday cage, especially where the bed is not fully surrounded or there are gaps around the sides. In practice they reduce a meaningful amount of RF exposure from nearby wireless signals, but the result varies with your room layout, device locations and reflective surfaces.
No. Swiss Shield® fabric is PES-coated and non-conductive, so the sheets reduce incoming RF signals without grounding. You do not need to connect them to mains electricity or a grounded wall or floor. If you choose to combine them with other grounded products, follow the manufacturer's guidance and electrical safety practice.

Both are breathable Swiss Shield® fabrics with exactly the same composition. Ultima has a slightly tighter weave, which gives slightly more protection across the cell and WiFi bands: up to 44 dB against 42 dB at 700 to 750 MHz, and about 36 dB against 34 dB at 2.45 GHz (2.4 GHz WiFi).
Swiss Shield® fabric, which is 82% cotton, 17% copper and 1% silver. The yarn is cotton fiber spun with a gossamer-thin silvered copper thread, 0.02 mm (about 0.0008 inch) across, and a PES coating makes the fabric non-conductive. The fabric is developed and manufactured in Switzerland, and the bedding is made in the UK.
Yes. Swiss Shield® fabrics, including Naturell and Ultima, are certified to OEKO-TEX® Standard 100, Product Class I (baby articles), which means they have been stringently tested for harmful substances.
It depends on the fabric and the frequency. Ultima provides up to 44 dB at 700 to 820 MHz (4G LTE), about 41 dB at 900 MHz and about 36 dB at 2.4 GHz WiFi. Naturell provides about 41 to 42 dB, 37 dB and 34 dB at the same frequencies. Every 10 dB is a tenfold reduction in signal power. These are laboratory figures for a single layer of fabric, and real-world results depend on how much of your sleeping area is covered. See the Specifications tab for the full table.
Yes. The fabric provides about 27 to 44 dB of shielding at cell frequencies (700 MHz to 1800 MHz), mid-band 5G (3.5 GHz) and both WiFi bands (2.4 GHz and 5 GHz), depending on the fabric and frequency. Shielding is strongest at the lower cell frequencies and falls as the frequency rises.
Only modestly. Independent testing up to 40 GHz shows about 16, 13 and 11 dB for Ultima and 17, 14 and 12 dB for Naturell at 20, 30 and 40 GHz. If millimeter wave 5G (24 GHz and above) is your main concern, contact us for advice on the right product.
Fit the mattress cover over your mattress and mattress protector using its elastic corners, put your duvet and pillows into the EMF covers, and make up the bed with your usual sheets, duvet cover and pillowcases on top so the shielding fabric sits beneath them.
Yes, we recommend it. Keep the Swiss Shield® fabric beneath your normal bed sheets, duvet cover and pillowcases. The fabric can be washed up to 40 times, so using your everyday bedding as the top layer means you wash it less often, and it lasts longer.
Yes. The lightweight design makes them easy to pack and use in hotels or when visiting friends and family.
Yes. The fabric is lightweight, soft to the touch and breathable, and suitable for everyday use. The bedding fits like ordinary bedding, and from the outside your bed looks completely normal. The fabric itself is translucent (semitransparent) and a natural ecru or off-white color.
Yes, up to 40 times, if you follow the care instructions. Wash on a wool cycle or hand wash cycle only, in a front-loading machine, using a mild biological or ecological detergent. Never bleach or tumble dry: line dry (hang dry) only. Protect the fabric from undue mechanical stress. We recommend keeping it beneath your normal bed sheets and washing it only when needed, so it lasts longer.
We recommend using the sheets as supplied, because cutting or altering the layers, stitching or construction may reduce shielding effectiveness. If you want to create a custom enclosure, such as lining a room or blocking a specific wall or window, contact us to discuss tailored fabrics or accessories such as Faraday tape that suit more complex projects.
Yes, we offer 30-day returns. If you are not completely satisfied, just let us know. As long as the bedding is undamaged, we will happily accept a return. See our returns policy for details.
