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 (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).
