Our Premium Grounding Underlay Sheets are cut to fit real mattress sizes — not a one-size-fits-all sheet.

For most beds, simply choose the size that matches your mattress:

• Single: 200cm × 70cm (fits any bed size)
• King Single: 203cm × 107cm
• Double: 203cm × 140cm
• Queen: 203cm × 153cm
• King: 185cm × 203cm

Need a larger fit?

The sheet can also be rotated sideways for wider beds.

A Queen underlay can fit a King mattress by turning it sideways, so the 203cm length runs across the width of the bed.

A King underlay can fit a Super King mattress the same way.

This covers the main sleeping area of the body and only leaves the pillow area uncovered, which is fine because your body is still resting over the conductive section.

It feels similar to a soft, light denim material.

No. We don’t recommend using mattress protectors, thick toppers or padded underlays between your body and the grounding product, as they can create too much interference and reduce conductivity.

For best results, place only a normal bed sheet over your Premium Grounding Underlay or Grounding Bed Mat.

Yes. Our Premium Grounding Underlay is designed to sit under your normal bed sheet — fitted or flat — so you don’t need to sleep directly on the conductive material.

For best results, avoid placing thick waterproof mattress protectors or heavy padded layers between you and the underlay, as these may reduce conductivity.

Yes. You can still wear pyjamas.

Direct skin contact isn’t needed. Your body can build up voltage from nearby electrical appliances and wiring, which can be tested with a multimeter.

The underlay connects you back to earth through your sheet and light sleepwear, helping discharge that buildup while you sleep.

Premium Grounding Underlay Sheets

Used under your normal bed sheet. They don’t require direct skin contact and only need washing every 4–6 months.

Cotton and Silver Fitted Grounding Sheets

Used like a normal fitted sheet and require direct skin contact. These can be machine washed as needed.

Premium Grounding Bed Mats

Used with a normal bed sheet over the top. If cleaning is needed, simply wipe the mat down with a non-abrasive cloth.

All three options can effectively ground the body. The main differences are the material, feel, setup and cleaning method.

Stainless steel 316 is medical grade and can handle regular exposure to corrosive elements, making it our most durable earthing product.

Machine wash every 4–6 months on a cold or warm delicate cycle with mild liquid detergent. Line dry only.

Avoid bleach, fabric softeners, whitening detergents, oils, tumble drying and high heat.

Yes. Power boards, double adapters and extension cords are designed to connect to the earth outlet.

No. The earthing sheet does not connect to active electricity. It only connects to the earth pin of your power outlet.

The power point doesn’t need to be switched on for it to work. The top two pins of the plug are plastic and non-functional. Only the single bottom pin connects to the earth, which safely grounds the sheet.

Every grounding cord also contains a built-in 100kΩ safety resistor for added protection.

Australian homes are required to be earthed for safety, but a multimeter is an easy way to check that your grounding product is working correctly.

Unlike basic continuity testers that only show a green light, a multimeter can show the voltage in your body reducing when you are grounded.

120-Day Trial

Try your Premium Grounding Underlay properly at home. If it’s not for you, you can return it within the trial period.

3-Year Warranty

Covers manufacturing faults and product defects.

Optional 10-Year Conductivity Cover

Available as an optional add-on near the Add to Cart button.

Because our underlay sits protected beneath your fitted sheet, it only needs washing every 4–6 months — far less than fitted grounding sheets that are exposed to sweat, friction and regular washing.

If added to your order, this cover protects your underlay’s conductivity for up to 10 years under normal household use.
