The Premium universal earthing undersheet is back. And it's updated to the high level quality we always offer. 
We produce this under our own label.  

It took us more than 4 years to develop the patented fabric of the Premium earthing undersheet. Five years ago when we introduced this Premium earthing undersheet we were already happy with its quality. 
The unfortunate fire of 2024 in the factory where the fabric is made gave the opportunity to update the fabric to the next level-quality. The light gray fabric has now 40% solid surgical grade stainless steel fibers. It is designed to maximize the conductivity of the robust material but at the same time feel like cotton, soft and flexible.
We use patented antibacterial tencel earthing fabric that comprises 40% solid medical-grade stainless steel fibre with German-made Tencel and natural antibacterial mineral fibre. It feels soft, and is flexible and breathable.

That is why we can also offer a 2-year warranty on its functionality.

The advantages of the patented Premium earthing undersheet are:

• contains  40% very fine surgical grade stainless steel fibers for optimum durability and conductivity.

• contains 60% environmentally friendly Tencel and specially designed mineral fibers with strong anti bacterial action for extra hygiene, like silver does. 

• you use it under your own favorite fitted sheet, just like our 50% silver earthing sheets.

• stainless steel is not sensitive to acids or sulphur from perspiration and skin oils and chemicals in personal care products. 

• needs to be washed less often, so less wear and tear

• specially designed to last much longer, expected to last 5 years or more

• 2 years warranty on wear and production errors as well as on the proper functioning (conductivity) of the earthing undersheet

The conductive part of this earthing undersheet is 90x200cm
At both ends there is a tuck-in strip of 70cm long, it is made of 100% Tencel.
Overall, the Premium universal earthing undersheet is 93cm wide and 340cm long.

Health effects
Choose an earthing undersheet to ground most of your body while you sleep. You absorb the maximum amount of energy from the earth in the form of electrons.
Night-time is the ideal time to ground yourself, because your body can recover best during sleep. This allows you to reduce complaints in a natural way and improve your self-healing capacity.
Sleeping on an earthing undersheet reduces stress in your body, allows you to sleep more deeply, snore less and wake up feeling more rested. This improves your immune system, makes you feel better and look better!

Environmentally friendly Tencel
Tencel (or Lyocell) is a completely natural raw material, made from eucalyptus wood from sustainably managed forests. The production process in Germany is also very environmentally friendly. Tencel is as soft as silk, as easy to care for as acrylic, as cool and pleasant as linen, as warm as wool, and much more moisture-absorbent than cotton.

Universal
The universal an earthing undersheet fits any single mattress or double mattress.
For a double bed, the an earthing undersheet can be placed across the mattress and tucked in on both sides of the mattress.
Or choose two universal an earthing undersheet so that both are maximally grounded.

How to use
Place the Premium universal an earthing undersheet under your own fitted sheet, just like with our 50% silver earthing sheets. Skin moisture creates conductivity through your own fitted sheet to the earthing undersheet, grounding you without the need for direct skin contact with the earthing undersheet. 

Because skin oils and perspiration are initially absorbed by your own fitted sheet, the conductivity remains optimal for longer. This means it needs to be washed less often, once every 1 to 2 months. All of this greatly benefits its lifespan.

For good conductivity, we recommend using a fitted sheet made of natural fibres such as cotton, viscose or Tencel, with few or no synthetic components. Polyester, for example, is a synthetic material and does not conduct earth's electricity.

Connecting to the earth: select this option during the ordering process.
We supply a 5-metre connection cable with the sheet.
During the ordering process, choose a earthing adapter or ground rod. Your earthing product must be physically connected to the earth.

Earthing adapter
Connect the connection cable of the earthing undersheet to the earthing adapter in the grounded outlet. The adapter is made of synthetic material and does not come into contact with electricity. The metal plates in the adapter only make contact with the earth wire/earth terminal of the grounded outlet. 
3 earthing products can be conneted to the earthing adapter. 

Ground rod
Or connect the connection cable to the ground rod. This has a 15-metre long strong cable.
uide the ground rod out of the window or door and insert it into the ground in the garden. The cable can be bent slightly so that your window or door can be closed.
With a splitter, an infinite number of products can be connected to the ground rod. 

If you have the choice between using a ground rod and an earthing adapter, we recommend using a ground rod for the earthing undersheet, especially for people who are (highly) sensitive.

Unique: 2-year warranty on wear and tear, manufacturing defects and the proper functioning of the earthing undersheet.
We offer a 2-year warranty on this earthing undersheet for wear and tear and manufacturing defects, provided that the maintenance instructions included in the plastic cover of the earthing undersheet have been followed. This unique warranty covers not only all manufacturing defects but also the proper functioning (conductivity), i.e. the effective grounding, of your earthing undersheet!

The expected lifespan is 5 years or more.

Testing your earthing undersheet with a product tester at half price or a multimeter at 30% off 
The product tester is a sensitive device for determining if there is electrical conduction between two points. When you purchase an earthing undersheet, you get 50% off the product tester. 
With the product tester you test:
1. Whether you yourself are grounded when in direct contact with the earthing product,
2. Whether everything is properly connected and your earthing product conducts properly,
3. Whether a cable conducts properly,
4. Whether your earthing product is grounded (via ground pin or grounded outlet),
5. Whether your outlet is grounded.
6. Whether after years of using the earthing product is still conductive. 

Testing with the Earthing multimeter measures the decrease in AC voltage (in digits) once you are grounded. You receive a 30% discount on the Earthing multimeter with the purchase of an earthing product.  
With the Earthing multimeter you test in millivolts: 
1. Whether you yourself are grounded on (in)direct contact. So you can also measure the decrease in AC voltage with clothing on or when you test with your own fitted sheet over the earthing product,
2. Whether everything is properly connected and your earthing product conducts properly,
3. Whether a cable conducts properly,
4. Whether your earthing product is grounded (via ground rod or grounded outlet),
5. Whether your outlet is grounded.
6. Whether after years of using the earthing product is still conductive. 
.
In the ordering process, choose the option for a (or no) tester. When purchasing an earthing product, we recommend purchasing a tester. This allows you to check after each wash to see if the earthing product is reconnected properly and if after years of use the stainless steel fibers still conduct. 

Washing
The earthing undersheet can be machine washed at 40-60 degrees.It must be dried on the line only. 
Please note! Spin this sheet at a maximum speed of 600 rpm. This will keep the stainless steel fibres intact. 
For detailed washing instructions see 'frequently asked questions'.
Each earthing undersheet comes with extensive washing instructions. See the inlay of the package.
