Product details

EMF and RFR Bed Mat for Under-Bed Shielding

This bed mat is made from BlocWiFi, a conductive nickel, copper and polyester fabric with 70 dB of shielding at 1 GHz. It goes on the floor underneath your bed and blocks radio frequency (RF) radiation, such as WiFi and cell signals, that reaches the bed from below. Wireless signals pass through floors and ceilings easily, so a neighbor's router in the apartment below, or a cell signal rising from the lower floor of your own home, reaches a bed that is otherwise shielded on the sides and top.

Completes a Canopy Into a Faraday Cage

A BlocSilver® bed canopy shields the sides and the top of the bed. The bed mat covers the bottom. Spread the mat out on the floor beneath the bed, covering as wide an area as possible, and let the canopy drape down to touch it. Where the two connect, they form a complete seal, a Faraday cage around the sleeping area. Without the mat, there is an open gap under the bed for signals to come through, which matters most on any floor above ground level.

70 dB of Shielding at 1 GHz

The mat uses BlocWiFi fabric, which provides 70 dB of shielding from 100 MHz to 3 GHz. Every 10 dB is a tenfold reduction in signal power, so 70 dB reduces the signal passing through the fabric by a factor of ten million. That range covers cell signals and 2.4 GHz WiFi, the signals most likely to rise through a floor. For more on the fabric itself, see BlocWiFi fabric.

The Mat Needs to Be Earthed

BlocWiFi is conductive, which is what makes it such an effective shield, but it also means an unearthed mat can pick up low frequency electric fields from the wiring around it. In almost every case the mat should be earthed. Once it is connected to earth, it reduces those electric fields instead of collecting them. Use the EMF Canopy Grounding Kit: its metal plate penetrates the mat, which lets you connect it up. The same kit grounds a canopy, so one kit can earth both. If you can, earthing directly into the ground outside with a copper rod is the most direct route; see our grounding rod. Our video below, Why do I need to earth?, explains how earthing works.

Setting Up the Mat

  1. Spread the mat out on the floor under the bed, covering as wide an area as possible. The label is printed on one side, so place that side facing down and use the other side facing up.
  2. Connect the mat to earth with the grounding kit, using the metal plate that penetrates the mat.
  3. If you use a canopy, drape it down to floor level so it touches the mat all the way around.
  4. Keep the bed at least 6 inches (15 cm) away from any wiring in the walls.

Six Sizes, From Crib to King

Choose the size that matches your bed: Crib/Cot, Twin, Full, Queen, California King or King. Prices range from $225.99 to $499.00, depending on size. If your bed is an unusual size, speak to an expert before you order.

Mat or Grounded Sheet?

The bed mat goes on the floor under the bed and shields it from below. If you want a grounded surface to sleep on, the Grounded Bed Sheet goes on top of the mattress and connects to earth. The two do different jobs.

Care

Wipe the mat down when needed. Do not wash it.
