What is an Earthing Sheet Underlay?

It is a thin underlay for earthing that you place under the regular cotton sheet that you sleep on.

Better Earthing Patented Fabric & Naturally Antibacterial

This custom-made earthing fabric is made with the highest quality medical grade (316L) solid stainless steel filament (15%), German Made Antibacterial Mineral Fibre (10%), and sustainably produced Lyocell/Tencel from FSC Certified forests (75%). 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 deep. 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 3-month 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 90 days of purchase if there is a manufacturing defect. Resellers may extend that warranty, but a 90-day manufacturers warranty is not a sign of confidence of durability.

More about Better Earthing Underlay 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.

Most earthing sheets are designed for direct contact with bare skin and use silver-coated fibre in 3-8% of their earthing fabric.

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 instead use as an underlay.

Fabric Appearance

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.

Washing Frequency

When used as an underlay, wash each 3-4 months in warm or hot water to avoid the build-up of oils from your hair and body. Oil acts as a barrier to good conductivity until washed out. This fabric is naturally antibacterial and remains hygienic between washes. If slept on directly, wash each 2 to 3 weeks.

Washing Instructions

Regular machine wash on warm or hot with a detergent that does not contain bleach as this will degrade its antibacterial effectiveness over time. Use any eco friendly detergents like Earth Choice, Aware or Abode as they typically do not include bleach. Use warm or hot water as this will help remove body oils and lotions. The build-up of oils acts as a barrier to good conductivity and can reduce earthing strength until washed out.

Drying Instructions

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. You can tumble dry on LOW for final drying only. Do not tumble-dry when wet, as this will increase the crinkle. 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).

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.


This Better Earthing product comes with a 5-year warranty on its earthing effectiveness, plus a 1-year satisfaction guarantee.

10 reviews for Premium Earthing Sheet Underlay Fitted by Better Earthing

  1. Ken, VIC

    My wife and I are quite happy with your product. It appears well made and robust. A lot better than those made with silver thread that have to be handled so carefully to avoid damaging the continuity and therefore the connection to the earth . Once continuity is lost, the product is rendered useless, an expensive risk, as replacement is not particularly cheap, particularly for those who are retirees. We have had three previous attempts. Two with the silver threaded fitted sheets and one with carbon fibre filaments in a flat sheet, none of which gave a reasonable service life. When we heard about the stainless steel filaments, we looked again and found your product which we are hoping will be more reliable and robust. We know from our personal experience that the earthing process works well to overcome inflammation, not only in the joints, but the whole body, wherever inflammation may be hiding, and we look forward to having a product that will give us service over a reasonable length of time without troubles. Judging by your performance to date, it appears that we an expect good back-up for the product too. Keep up the good work and thank you for your prompt service.

    I have had my earthing mat for about two months now and I love it! The first few nights were a heavy detox and was like waking up with a hangover. Now I am sleeping more deeply and if woken in the night, I get back to sleep straight away.

    My bloke only sleeps over a few nights per week and he loves it too! He notices the difference and sleeps less deeply when back at his house, without a mat.

    If I indulge in wine, I still sleep well and haven’t had a hangover, which is all thanks to earthing!

  3. Robert, WA

    You have gone above and beyond your internet supply colleagues in the information and follow up emails and phone call to us as well as your concern with my Wife’s Atrial Fibrillation issues. Frankly I’m blown away with your service and compassion, it seems to be a rare quality these days. We have been involved in top end products and customer service for over 40 years so we appreciate not only the quality and presentation of your products but the dearth of information that you provide.

    To top it off, the results have been terrific for myself and will hopefully be a future benefit for my wife as well. As previously mentioned I have suffered a lower back injury since my teenage years and as time has moved on the pain in my groin, leg and buttock muscles has gradually increased to the point whereby I was finding it difficult to walk any distance and found it hard to start moving when getting out of bed in the mornings. I like to think that I have always kept reasonably fit through exercise and diet over the years but it seemed that it was catching up with me. I have always had Chiropractic care on a regular basis and recently with a young health conscious Chiro that has had experience with a number of forms of care. He is also is aware of Earthing/Grounding and has also noted the difference it has made for me in just a short time.

    We look forward to using the caravan equipment that you have provided, it will be great when free camping and some of the parks we go to may have dodgy electrical set ups, although they should comply regardless.

    Thank you again and we will look forward to a better quality of life that we have left to live in the future.

  4. Barb & Mike, Shipley Organics

    I’m sleeping more soundly and usually get up less during the night. Better still, I go back to sleep very quickly when I do get up and spend less time solving the world’s problems!!

  5. Becky Pell

    Loving it – I am completely sold on the concept and I’m spreading the word! Sleeping super soundly and my husband, who was sceptical at first, now says he’s sleeping much better after years of broken sleep and he says it has to be the sheet. I’m also enjoying the portable mat which follows me round the house when I’m working at the computer or reading or doing yoga – I’ll be taking it on work trips and I’ve just ordered one for him for Christmas to use when he’s at his desk. The book is fascinating, and I’ll be recommending the idea to my yoga therapy clients. Thank you!

  6. Rita, NSW

    All 6 adults using the underlay and 1 child are sleeping deeper and more soundly. Even those of us that didn’t feel we had any sleeping issues.
    I couldn’t even have one glass of wine without waking up at 2am. Now I can have a glass and i dont wake up till my normal wake time.

    Im a big walker and can feel tired in the afternoon but now i don’t get tired.

    My husband said hes more flexible.

    My son tried the green wrist band for strain to his arm from repetitive work. He trued it witout using the underlay and in a couple if days he noticed significant pain reduction. When he started using the underlay his wife said his intense grinding if the teeth at night diminished by about 80%.

    My son in law broke out in a strange rash on his belly and my granddaughter broke out in a hives. No way of knowing if it is a coincidence or because of the underlay. Peter suggested to give it a break for a few days… just in case and then start again slowly.

    The 3 of us in our household seem to be calmer.

    Looking forward to the possibility of other positive results.

    We eat a very health diet and take great organic food supplements. None in our household Are on any medication so its amazing to notice these rather significant results… im hoping we may even b able to reduce our supplement bill in the future!

    Thanks for your great products. I loved the way they arrived so beautifully packaged and that they look and feel like a quality luxury product…. and they are!

  7. Omar, Malaysia

    I received the beautifully packaged products albeit slight delay due to the products being held at the customs office here. I purchased them to replace the older earthing sheet that I have used for quite a long time. What’s better is that I could sleep on my favourite bedsheets over the underlay. Your product is definitely a Better Earthing ! I am getting better sleep and gets up refreshed every morning. Thank you Better Earthing.

  8. Rachel C, VIC

    Thanks so much for the underlay – it’s fantastic! I’m sleeping so much better already. My young son also enjoys sleeping on the earthing underlay.

  9. Dave J, NSW

    I’m loving it! Best thing I’ve ever done! I’m sleeping and feeling better. I’m raving about grounding to everyone.

  10. Belinda VIC

    Thank you better earthing this sheet has helped me and my partner I’m not waking as much with hot flashes or putting the blankets on and off as much, and I’m only going to the toilet once a night now instead of 3 times a night, my partner has the mat as well and his back is much better and he hasn’t had gout since using the mat and the sheet and we are both waking up much better so thank you.

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 powerpoints 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 powerpoint 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 powerpoint. 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.
