We are the original inventor-makers of the earthing sheet underlay (earthing undersheet). Our Australian made earthing underlays are the most advanced and durable worldwide. Our Premium earthing underlay is backed with a 5-Year warranty and will outlast every other earthing sheet, earthing sleep system or earthing sleep mat worldwide. It is also certified antibacterial for ongoing hygiene.
This patented Better Earthing fabric took us over 2 years to develop and includes solid medical grade stainless steel filament, The fabric and underlay is made to maximise earthing conductivity from the robust metal, and yet still be flexible and soft. Please see details on its earthing effectiveness warranty and our made-to-last materials in the Warranty tab below.
This earthing sheet underlay is available in Single, Double, Queen, King, Extra Large King, and most other sizes (also see our Universal earthing underlay flat sheet or half-sheet sizes).
Place your Better Earthing Underlay Sheet on top of your mattress protector (and electric or magnetic blanket) and then place your regular cotton sheet on top. Our patented fabric includes special German-made fibre made with natural antibacterial minerals, making this bedding hygenic between washes (machine washable see Care instructions tab).
Unlike silver or carbon-based earthing sheets and earthing sleep mats, you don’t need to be concerned about damage from various ingredients in body creams, lotions, essential oils, magnesium oils, sulphur in heavy sweat, body and hair oil. We just don’t say our products will last, we back our words with a 5-year warranty, and logically it will continue to earth effectively for 15 plus years.
It delivers big health benefits including improved sleep, reduced pain, and better circulation. See earthing benefits for more or read our 100+ customer reviews below.

This custom-made earthing fabric is made with the highest quality medical grade (316L) solid stainless steel filament (20%), German Made Antibacterial Mineral Fibre (10%), and sustainably produced Lyocell/Tencel from FSC Certified forests (70%). It is permanently antibacterial (certified) and will prevent bacteria and odours from occurring within the fabric throughout its lifespan. Many fabrics are not permanently antibacterial and only have a solution added which washes out quickly.
The side skirt is 100% cotton and 40cm (16 inch) deep, and (50 cm deep in Extra large king). The fit is generous to suit deep mattresses and those with an additional soft top.
Fabric Feel & Appearance
This fabric is light grey in colour, with a natural crinkle due to the long and highly robust medical grade stainless steel filaments. This filament is much more conductive than more commonly used stainless fibres. The fabric feels like strong cotton or linen fabric, and you can earth effectively for many years while sleeping on your favourite regular cotton or natural fibre sheets.
Comparison to Other Earthing Underlays
This premium product is far superior to black carbon-coated earthing sleep mats made from Polyurethane (marketed as Leatherette and made in China). Our premium earthing fabric has much better earthing conductivity, superior durability and reliability of conductivity over time. It is also more breathable, and more hygienic, all of which are important for an underlay. We back our durability confidence with a 5-year warranty.
In comparison, black polyurethane earthing sleep mats have a 1-year manufacturer warranty against defects. The maker says under their return policy (Sep 2019) that they should last for years or a lifetime, but they only offer to refund or replace within 1-year of purchase if there is a manufacturing defect.
More about Better Earthing Underlay or Undersheet Design:
Better Earthing Sleep Systems are the world’s first earthing sheet that is designed to work through bed clothing and the fitted sheet you directly sleep on. NO direct skin contact is needed. The tiniest amount of body moisture or humidity in your clothes and sheets, compressed by your body weight, creates conductive channels that very effectively pass earth from your highly conductive Better Earthing Sleep System.
By not sleeping directly against your earthing undersheet, the fabric is protected from normal wear & tear, which makes it last longer.
Other earthing sheets are designed for direct contact with bare skin and use silver-coated fibre in 3-8% of their earthing fabric compared to around 15% solid stainless steel filament in our premium range.
Please note if you have an allergy to nickel in stainless steel or to 9 or 14-carat gold, then avoid direct skin contact whilst sleeping (which will happen when you use it as an underlay).

Premium Earthing Underlay by Better Earthing, Better Earthing Adapter, Better Earthing Straight Lead (if you prefer a coiled lead please leave a note in the checkout), Flat & Tight Underlay Set-Up Kit including 10 straps and 20 easy-release buckles. Product Guide & Set-Up Guide.
This fabric has a crinkly crepe-texture appearance due to its highly conductive and solid medical grade stainless steel filaments, which is a natural property of this fabric. It can be used as an underlay with your favourite sheets (cotton or any natural fibre). Please note if you have an allergy to nickel in stainless steel or to 9 or 14-carat gold, then avoid direct skin contact whilst sleeping and use only as an underlay.
Machine wash on 'hand-wash' or 'wool wash' setting with a low spin cycle (400-600). Use either warm water (30-40c) or cold water with presoaking beforehand in an Oxy soaker (see washing frequency for more). Wash with a detergent that does not contain bleach as this will degrade its antibacterial effectiveness over time. Choose an eco-friendly detergent like Earth Choice, Aware or Abode as they typically do not include bleach.
Every 3-6 months. This fabric is naturally antibacterial and remains hygienic between washes. Presoak every 2nd wash in an oxidiser soaker to prevent the build-up of body oils as they act as a barrier to good conductivity and can reduce earthing strength until washed out. Oxidising soakers are fine to use as our Stainless Steel filament does not oxidise.
This fabric has a natural crinkle and will pucker after washing. Hand-stretch the wet fabric by stretching the sides in opposite directions (stretching the sides apart). Line dry inside or outside. Do not tumble-dry. Do not dry clean. As this fabric is highly antibacterial, you can place it on the bed when it is not yet 100% dry (it will not develop mildew or other odours).
This new design includes straps and buckles to tighten the earthing underlay around the mattress so that it stays tight and flat. See set-up video further below.
Please note the FIRST TIME SET-UP IS 30 MINUTES. Two people are recommended to lift the mattress off the bed so you can lay the straps onto the bedframe.
You then only need to WASH EACH 3-6 MONTHS, as the underlay is certified antibacterial.
Removing the underlay to wash takes 5mins for one person, and 10minutes to place it back on the bed. Reclipping the buckles/straps back on is much faster than setting up.
Rotating a mattress can be done with the underlay remaining strapped to the mattress.
Why Antibacterial Fibre?
Earthing products will naturally build up some sweat and body oils from normal use. This build-up can create a breeding ground for bacteria, mould or mildew.
Anti-bacterial fabric actively kills or inhibits the growth of bacteria, including those that cause odour.
Better Earthing does not use chemical antibacterial treatments or additives, which are not long-lasting, and can cause skin allergies.
We use German-made natural antibacterial mineral fibres, as part of the fabric composition. This means this product is permanently antibacterial, or antibacterial for its life.
Other benefits in addition to hygiene include less washing needed, plus longer fabric lifespan and lower replacement costs over time.
Better Earthing Premium Underlays (fitted or universal) and made with stainless steel filament come with a 5-Year repair or replace Warranty against manufacturing defects and to earth effectively when used as an underlay in accordance with the set up and care instructions.

Indoor Earthing Explained
This Better Earthing Sleep System comes with a special adapter plug and lead designed for earthing indoors.
All Australian and New Zealand power points have a third ‘earth’ pin (at the bottom) that is wired to a metal rod or plate buried in the ground. This safety mechanism is called grounding – it’s there to send excess electricity back into the ground (earth). Indoor Earthing products use ground wiring in your home to safely pass free electrons from the earth to your indoor earthing product, then to you.
No electricity is used. You can earth with the power point turned off. The top two prongs of Better Earthing adapter are plastic, instead of metal like a normal plug, so no a/c current from your electricity mains can pass through.
Both the Better Earthing Adapter and Lead have built-in safety resistors totalling 60,000 ohms. This protects against the rare (or theoretical) event of a power surge via the earth. If the nearby ground were struck with lighting, barely a mosquito bite of electricity could pass through these resistors. Better Earthing adapters conduct earth only. It is a safe and easy way to receive the earth’s health-enhancing free electrons from the comfort of your home.
You can use an autorange multimeter (sold separately) to verify that your products are correctly Earthed via the power point. Compare the amount of electrical voltage carried in your body when you are not earthed, compared to when you are earthed. You’ll be amazed by how much excess AC electricity your body can pick up from surrounding electrical cables and devices and how much it dissipates (reduces) when earthed.
There is also an optional outdoor earthing rod and 15m lead if you don’t wish to earth via the indoor earthed wall socket.
